Are you referring to pictriev or rekognition? I assume the latter since you mentioned glasses?
Hi All,
DISCLAIMER: I do not work for either Pictriev or Rokog, I only researched them for use in implementation of computer vision recognition systems for companies I work for. Both have privacy pages that have an agreement you "sign" into by uploading images, you should read those.
http://www.pictriev.comhttps://rekognition.com/index.php/demo/facePictriev is a gimmick or toy, comparing you to celebs and Rekog uses actual openCV and algorithms that government, commercial and private agencies use for tracking of humans. Rekog has a SDK and you can embed it in your own code to build face recognition into your own applications. You have access to a bunch of statistics about the image, many of which have a decent accuracy rate. Many companies use it to track shoppers, emotional reaction to ads or displays, employee tracking, facial security login areas and a bunch of advanced stuff that would probably make you feel sick. The government uses it in terrorist tracking, airport security, street cam tracking, and a bunch of advanced stuff that again would make you sick. I read someplace about movie theaters using the emotional tracking of the faces in the crowd to help directors determine how the sequels should be written in order to keep an audience captivated in a planned series.
Beards cause problems for
ALL face rec systems even the ones deployed by our governments / military . You can search many articles on that in the news. This makes terrorist hunting harder.
Note: Computers can be tricked. Computers don't care what gender or race you are or if you are happy they only report what they determine from visual analysis. If a computer thinks you look male or female that DOES NOT mean that a human would determine the same results. So never just rely on what a face recognition system says, get human input.
Their are some makeup tricks you can do where these systems, even the advanced ones will not even recognize you as a face and therefore not track you. Look it up in the news they talked about it a bit last year. Its fun.
Pictriev sometimes will see me as 11 year old male that is a cross between Ozzy Osbourne and Emma Watson. I put in celeb picts and even those are not accurate. I even uploaded the same pictures at different times and got very different results. The age result is very inaccurate consistently. When I upload a combined photo of faces the algorithm only finds 30% of the faces in the photo. The gender results are all over the map, even when uploading the exact photo as before I can get different results.
Rekog sees me as female most of the time. As do other high end computer vision recognition systems. The age rates me younger than my actual age by about 10 years. (thats nice). I have tested lots of photos of others and the Age on Rekog is pretty close. When I put in older pictures of me in my 20s many are rated male and the age is right on target. When uploading a combined photo of many faces Rekog sees most of the faces. Uploading the same image at a different time is 98% identical results. The gender results hardly ever differ when the same image is used.
Important Note, Rekog may be learning! I may have submitted enough pictures of myself that even on a day where I look bad (scruffy) rekog says I look female, it may be comparing me to its earlier results? / images of me.
I have been very interested and involved in computer vision systems since I was a kid in the 80s, we have advanced by leaps in just the past few years and in the future every physical space in the real world will be being analyzed within the cyber world in real time. Computers already predict traffic/crime patterns, track suspects, follow persons of interest on all our major streets and public transport systems. We are being bombarded by WiFi that can also be used like radar in order to track detail 3d images of inside our homes and businesses. Tons of people carry around a device that shows their exact location, the position of the device, sounds and images around it, etc. Eventually, if not already.. governments will have the computer capability to track all of this info on computers and zoom in realtime into a location and evaluate what is happening at that location, even in private areas. Computers could alert to potential problems. Sure call me paranoid, I don't care... I just know what computers and savvy tech people can do with lots of government contractor money.
Use Pictriev and Rekog at your own discretion and remember that its just a computer algorithm, a real humans input is always good.
Love,
Jade
