That video we showed you yesterday made it appear that the HP MediaSmart PC with facial recognition doesn't work with black people. HP responded to that assertion, blaming bad lighting for the PC's inability to follow the face of that cool guy who demonstrated it so aptly in the video:
The technology we use is built on standard algorithms that measure the difference in intensity of contrast between the eyes and the upper cheek and nose. We believe that the camera might have difficulty "seeing" contrast in conditions where there is insufficient foreground lighting.Indeed, it's a tall order to achieve the proper exposure on the face of a dark-skinned person while surrounded by intense backlighting — in this case, the bright fluorescent fixtures clearly visible in the background. However, in the screen cap we grabbed above, the exposure on the man's face is adequate, yet the face tracking still wasn't functioning. We think HP needs to rebuild its "standard algorithms."
