Abstract:
1. A method for determining whether a portion of an image contains a face, comprising: determining a first value for a first region of an image, wherein the first region is within a particular portion of the image; determining a second value for a second region of the image, wherein the second region is within the particular portion of the image and is adjacent to the first region; generating a first feature value for a first feature, wherein generating the first feature value comprises determining a first ratio based at least in part upon the first value for the first region and the second value for the second region; obtaining a first value range that is associated with the first feature, wherein first feature values within the first value range indicate a likelihood that a face is present; determining whether the first feature value falls within the first value range; in response to determining that the first feature value does not fall within the first value range, storing data that indicates that the particular portion of the image does not contain a face; in response to determining that the first feature value does fall within the first value range: wherein the method is performed by one or more computing devices.
