Abstract:
1. A digital image processing method for locating faces in a digital image, comprising the steps of: generating an integral image from the digital image; generating a grid pattern image from said integral image, said grid pattern image having a grid pattern having a plurality of cells each of said cells having a plurality of pixels; reducing said grid pattern image to a corresponding base grid pattern element image, said base grid pattern element image having a number of pixels equal to the number of cells in said grid pattern image; providing a set of different orientation images, said set including a selected one of said base grid pattern element image and a predetermined mean grid pattern element image of sample face images and excluding the other of said base grid pattern element image and said mean grid pattern element image, said set also including a plurality of additional grid pattern element images, each said additional grid pattern element image being a different rearrangement of elements of the selected one of said base grid pattern element image and said mean grid pattern element image; and performing a correlation test between said images of said set of different orientation images and said excluded one of said base grid pattern element image and said mean grid pattern element image.
