Abstract

A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process image data captured by the camera. The image processor, responsive to image processing of captured image data when the camera is disposed at the vehicle, is operable to determine the presence of a pedestrian in the field of view of the camera. The vision system may utilize a linear classifier to identify areas where a pedestrian is more likely to be present for enhanced processing of those areas. The vision system may utilize a Histogram Intersection Kernel classifier for enhanced processing of identified areas. The vision system may utilize detection area filtering to reduce processing of image data representative of areas of the field of view where a pedestrian is not likely to be present.
