Abstract
For a subset of pixels in an image in which it is desired to detect a human face if one is present, a first variable is derived from the gray-level distribution of the image, and a second variable is derived from a preset reference distribution that is characteristic of the object. The correspondence between the first variable and the second variable is then evaluated over the subset of pixels, and a determination is made as to whether the image contains the object, based on the result of this evaluation.
