Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are disclosed relating to skin-tone filtering for reducing the impact of lighting conditions, while providing a low-computation solution for effective face detection. In one aspect, methods include sampling a digital image frame from among a series of digital image frames. The methods further include analyzing pixels within the sampled digital image frame to determine whether pixels in the sampled digital image frame have a hue, independent of lightness, that is within a range of hues corresponding to human skin tone. Further, the methods include deciding whether the sampled digital image frame includes a depiction of human skin based on a result of the analyzing.
