METHOD AND SYSTEM FOR DETECTING A HUMAN IN A TEST IMAGE OF A SCENE ACQUIRED BY A CAMERA

摘要

A method and system is presented for detecting humans in images of a scene acquired by a camera. Gradients of pixels in the image are determined and sorted into bins of a histogram. An integral image is stored for each bin of the histogram. Features are extracted fom the integral images, the extracted features corresponding to a subset of a substantially larger set of variably sized and randomly selected blocks of pixels in the test image. The features are applied to a cascaded classifier to determine whether the test image includes a human or not.
