SceneTap – “facial detection” … Friday debut of SF bar-cams stirs sour reception (May 17, 2012) …item 4.. Dr. No – Original Trailer (1962) — SPECTRE …
Image by marsmet511
SceneTap is using facial detection software, which gathers 12 data points off an image, as opposed to facial recognition software, which grabs 36 data points, according to Nieman.
The data contains information related to facial characteristics and compares that to a data base of generic faces belonging to a wide range of anonymous people and looks for the closest match, he said.

Friday debut of SF bar-cams stirs sour reception
With a new service called SceneTap set to put video cameras in bars, privacy advocates warn that a red line’s about to get crossed.
by Elinor Mills May 17, 2012 9:29 AM PDT
When San Francisco watering hole The Boardroom signed up last year to capture video at the bar and stream it live to the Web, manager Casey Gray liked the idea as a way to promote new business and remotely check in on what was going on.
So much for the best laid assumptions.
"At the time we didn’t have any security cameras here, so it provided a service to me. I could hop on the phone and see what the bar was doing," Gray said in a phone interview from The Boardroom, which straddles the city’s North Beach and Telegraph Hill neighborhoods. "I had 24-hour access, but the video might only show to the public for a few hours a day" on the Web. The service he was using was called BarSpace.
But after customers complained — including several male patrons who expressed concern that their girlfriends could check up on their activities via the video stream — The Boardroom turned off the camera after only a few months of operation.
"We stopped it because it was creepy and people didn’t like it," Gray said. "There was push back from a lot of different people."
In what must feel like a deja vu moment, Gray is letting another startup put video cameras in another bar called Tope, which he owns. Only this time there won’t be any streaming video of embarrassing or relationship-destroying bar room shenanigans.
Call it a sign of the times. Tope is one of about 20 bars launching a service called SceneTap in San Francisco on Friday. This may just be the start. SceneTap could conceivably prove useful for a variety of retail companies, providing data on when customers shop in stores, what items they browse, and other in-store behaviors and patterns. But it also raises expected hackles of privacy watchdogs who worry the data could be combined with a person’s online footprint to do what even Google can’t do right now — match your Internet activities with your offline world. (Oh wait, they could do that by using SceneTap in Google Street View cars!)
—–I left my personal data in San Francisco
SceneTap’s devices, located near the front entrance, keep track of the number of people who enter and exit a venue and use facial detection software on video feeds to figure out what gender and age customers appear to be. It provides that traffic and demographic information to bar owners who can design marketing and other promotions to target specific audiences, while users of the SceneTap app can see which bars in their area are "hopping."
That seems to be a far cry from sending live video to the Internet like the BarSpace service did, yet SceneTap has hit a a nerve in San Francisco, touching off a frenzy of criticism on blogs and social media sites.
"The people here care about our bars and clubs, we care about each other, and we take our privacy seriously around here," writes Violet Blue, a blogger at CNET sister site ZDNet. "We also know a lot about tech, so a startup that rolls in to carpetbag an invasive app space into clubbing is — in most ways — doomed to fail. There isn’t much SceneTap could have done to smooth over the idea of putting cameras into bars — in this city, anyway."
Managers of several bars in Chicago and Madison, Wis., where SceneTap has already launched, told CNET that they had not received any privacy complaints regarding the video cameras’ presence in the bars. The service is also operating in Austin, Athens, Ga., Bloomington, Ind., and Gainesville, Fla., according to the company’s Web site.
If SceneTap is getting this much heat before its San Francisco launch, how did BarSpace fare? Its domain is up for sale and the app is nowhere to be found.
BarSpace co-founder Michael Deignan told CNET that he and the other founders moved on to other ventures and shut down the service earlier this year. It had launched in 2009. "Up until we turned it off we had great traffic and a lot of customers," he said. "It made more sense to go over to a new company while it is hot and get it started. It’s a resource issue."
Asked if there had been privacy complaints or lawsuits filed over the streaming video, Deignan said:
"There were no lawsuits and no complaints. If there were, it’s nothing I heard about."
In fact, the startup got a spike in business following reports in The East Bay Express and the San Francisco Weekly last July that BarSpace was streaming from nearly 50 bars, he said. "It wasn’t anything like the shit storm SceneTap is dealing with."
Even though live video is perceived as more invasive, BarSpace’s video was taken of the whole room and not close up, and it was grainy with faces were blurred out, according to Deignan. Whereas, SceneTap appears to be doing data mining, he said, adding "Have you seen ‘Minority Report?’"

Andrew Nieman, director of business development at SceneTap, assured CNET that SceneTap is neither a reincarnation of BarSpace, nor a scene out of a scary sci-fi movie.
"We are not a check-in aggregator. We don’t show you what people are doing there. It’s a snapshot of data. It’s like getting a text message from a friend" who is in a bar describing the scene, he said. "We don’t record anything. We don’t want to have the liability of having anything recorded and it would be expensive to store all the feeds in the cloud…Our system offers a lot more anonymity."
SceneTap is using facial detection software, which gathers 12 data points off an image, as opposed to facial recognition software, which grabs 36 data points, according to Nieman. The data contains information related to facial characteristics and compares that to a data base of generic faces belonging to a wide range of anonymous people and looks for the closest match, he said.
Just because SceneTap isn’t doing more advanced facial recognition, which is used to identify specific faces, and doesn’t store the data or stream it live now, does not mean it doesn’t have the ability to add those capabilities or won’t at some time in the future. Did anyone ever think Google circa 1999 would be so much more than just a search engine?
"I don’t see us needing to go to that level or wanting to," Nieman said. When pressed later for additional comment on criticisms that the company’s spectre could evolve, he provided this statement: "SceneTap has no intention to use any type of facial recognition technology. If facial recognition, not to be confused with facial detection, becomes mainstream in the future and widely used commercially across an array of industries, we will assess the situation at that point."
—–Smile for the camera
A big privacy concern with facial recognition is that it will be matched up with data in the cloud and thus identify you, and in many cases out you, depending on where you are or what you’re doing.
"Even if they are warned, it’s a bar. People’s expectations of privacy in a place like that are" high, said Sarah Downey, online privacy analyst at online privacy firm Abine.
Many bars have security cameras installed, and no one seems to mind those. But, so far, their use has been as a deterrent or to rewind for crime investigations. "This is not security," said Downey, who created a rundown on facial recognition technology. "This is people watching."

In the rush to create innovative mobile apps and services, developers are failing to adequately understand the difference between activities and spaces that are public versus those that appear to be public but are considered private in context, said Jules Polonetsky, director of The Future of Privacy Forum. "We expect to be able to be obscure in public. We get that we are in a crowd, but we still don’t believe that everyone of us is such a celebrity that whenever we step out of the house it’s fair game for the app developer to use the data," he said. "Folks are trying to figure out what the lines are and it’s not clear. That’s why we see app developers pushing the envelope and causing a backlash."
The brouhaha over the privacy implications with SceneTap is causing at least one San Francisco bar owner to reconsider the decision to use the service.
"I’m almost about to yank the whole thing," said Colin O’Malley, owner of John Colins in the city’s South of Market district. "I didn’t think it was that big of a deal."
His plan has been to give it a shot for the three-month free trial and see if he’s really getting enough valuable information about customer demographics. But not if customers complain.
"If it’s too invasive for people, hey, I’m a man of the people and we’ll yank it out," he said. "If it starts to affect my business, it’s not worth it."

New app tracks male-to-female ratio at bars and clubs using “facial detection”
By Phil Tucker
SceneTap’s new location-based app tracks attendance, gender and more at bars and clubs in real-time.
img code photo … “facial detection”

Heading out for a night on the town? Chicago based startup SceneTap is looking to streamline the process of finding the perfect hotspot. Using “facial detection” software SceneTap tracks which bars and clubs have the most patrons and — more importantly — which have a favourable male-to-female ratio. Launching this month, SceneTap’s iOS and Android apps will provide users with real-time snapshot of what the demographics are at participating locations on any given night.
SceneTap will initially cover 50 bars in popular neighborhoods of Chicago, each of which will have a system installed with the ability to detect the number of patrons, their gender, age and more. This is accomplished using software which can detect human faces in video; many point-and-shoot digital cameras use similar algorithms in order to focus properly. Faces are then compared against a database in an attempt to determine the sex and age of the subject; are you a 25-year-old female? All of this valuable data is then combined and further analyzed to provide information such as the male-to-female ratio, the average age of patrons, who’s buying drinks and which bartender they prefer.
“This is going to change the way the bar industry runs” -Cole Harper, CEO, SceneTap
Even though it’s arriving hot on the heels of Facebook’s implementation of facial recognition, there’s a major difference between Facebook’s and SceneTap’s technology — SceneTap is anonymous. According to the company, there is no attempt to identify individuals (an activity known as “facial recognition”), but rather to discern gender, age and location within the establishment. These types of algorithms are referred to as “facial detection”, a subtle difference — but an important one. The distinction between these two terms revolves around identity; everything else about an individual is fair game as far as SceneTap is concerned.
For users the app is free; the company plans to make the bulk of its money via advertising and Groupon-like coupons. SceneTap will launch in Chicago in the middle of July and have partners in select cities across the U.S. shortly thereafter including New York, Boston, Miami, Austin, Columbus, Phoenix, St. Louis, San Diego and Las Vegas.
Slippery slopes and privacy concerns aside, I have to agree with the CEO — this is going to change the way the bar industry runs. The data this type of system could provide is unheard of in the industry. Aside from what’s already been mentioned, the potential is staggering — how many patrons left during a specific song? Or right after a particular promotion expired? How many patrons are dancing versus lounging? Are opposite sexes mingling? Are same sexes mingling? From an owner’s perspective adding a system like this seems like a no-brainer. For patrons there’s a new dilemma, do you head to the place where SceneTap says there’s a great gal-to-guy (or guy-to-gal) ratio or the opposite because everyone else is listening to SceneTap?
Do you think this use of facial detection will be beneficial or harmful to the public?

…..item 3)…. Masable Business … mashable.com … Startup Helps You Scope Out The Scene By Putting Cameras In Bars
June 10, 2011 by Sarah Kessler
The Spark of Genius Series highlights a unique feature of startups and is made possible by Microsoft BizSpark. If you would like to have your startup considered for inclusion, please see the details here.
—Quick Pitch: SceneTap tells you how crowded a bar is and what its gender ratio is in real time.
—Genius Idea: Relying on cameras instead of a checkin service to collect anonymous real-time data about a bar.
img code photo … the scene
Whether you’re looking for a bar where conversation is possible or the loudest, most crowded bar in the city, it’s hard to tell where to find it. SceneTap wants to simplify this process by incorporating a live count of how many people are in a bar, the range of their ages, and their gender ratio into an iPhone app.
Instead of relying on a checkin service that might give clues as to how crowded a bar is, what SceneTap CEO Cole Harper has in mind is an accurate tally of patrons — whether or not they use a particular service. He says about 50 bars have already agreed to install cameras at their doors that can identify the gender and approximate age of patrons as they enter.
When the cameras go live sometime next month, SceneTap users will be able to get a glimpse of what the current scene at those bars is like based on that data. They’ll also be able to chat with the bar and other SceneTap users (i.e. “Are there any tables available?”), see specials and purchase Groupon-like deals using the apps.
Harper hopes bars will pay to participate in exchange for detailed analytic information about their customer bases and a social, location-based marketing tool.
img code photo … Male Female … Customers Entered
But there are two obvious and somewhat opposing risks in opting in: that the technology will creep people out and that it won’t be accurate enough to attract consumers.
“It’s less intrusive than scanning IDs,” Harper says about the former concern. “No personal data is obtained and nothing is recorded.”
The technology only notes a person’s gender and approximate age, he says. Some display advertising already uses a similar technology to record impressions, and you could argue that more data is collected about you during a Google search.
In order to understand what kind of person is entering a bar, SceneTap’s technology matches a person’s image with a database of faces to determine relative age. If the person matches a photo of someone in the database who is 27, for instance, that’s the age the camera will assign him or her.
To what degree of accuracy this method can label people — is a 23-year-old’s face shape much different than a 37-year-old’s face shape? — is something we’ll be able to test when the service actually goes live. For now, it’s just an interesting idea to consider as you start planning your Friday night.
Would you find a service like this useful for making plans? Are you bothered by the idea of a camera tallying your anonymous entrance to a bar? Let us know in the comments below.

Learn How To Take Beautiful Pictures
What a great decision! Of course, there are so many different sources of information that it can be difficult to single out the most useful advice. Follow this easy, sensible advice to improve your pictures quickly.
A filter is a lens extension. You can screw a filter right on the lens to get additional effects. The most common filter is the UV filter. The rays from sunlight can damage your lens if it does not have a filter on it. A filter can also help protect your camera lens if you accidently drop it.
A principle of good composition you should learn is to limit the subject matter in a picture. Do not crowd a shot with unnecessary visual elements. When photographing people, try to take shots that your subjects aren’t aware of.
If your goal is to take great pictures, don’t skimp on your gear. A DSLR is a great choice of camera if you want to take top-quality photos. Successful photographers pay close attention to the type and quality of the equipment they purchase, so it would behoove you to do the same.
Organize your subjects into the right pose for you. Candid pictures have their advantages, but very few turn out as interesting as posed pictures. Posing your subject will increase the likelihood you get the shot you want.
A faster shutter speed is needed when taking photos in low level lighting. This will stop the picture from coming out blurred. Go with 1/200 or 1/250 setting on your shutter speed.
It may seem like a simple concept, but the way in which you hold your camera can have a huge impact on your resulting photographs. This is important because without proper holding procedures, you are not getting the most stable image possible. Make sure your arms are kept near your body and that you are supporting your lens using your non-dominant hand.
If you are photographing a bride or someone else in white, a contrasting background will help make their clothing stand out. A lot of the time cameras are set on auto focus. Auto focus means the camera is going to try and get a reading on everything in what the camera is seeing. Because of this, white clothing will seem pale within the photos.
After reading the information provided, you should now have a better idea on how to go about improving your own photography skills. You can also return to this article if you need. Keep practicing and learning, and in time, your photographs will be works of art.
