/ METHOD AND APPARATUS FOR DETECTING FACE WITH LOW ENERGY OR LOW RESOLUTION

摘要

According to the present invention, in low-energy and low-resolution face detection, a face is detected by sliding a window while reducing an image to a resolution corresponding to a window size for face detection with respect to an input image, For the windows that have passed through the prefiltering, the final block of interest is extracted by matching with the local block texture feature and feature template. Then, It is possible to more efficiently detect face and person having low energy or low resolution by detecting faces using a classifier having a relatively large amount of calculation.
