Abstract
A pedestrian detection system and method includes: dividing an image to a plurality of granules, and counting magnitude difference value of each granule in diagonal orientation to obtain features of HOGG. And the HOGG and the HOG captured can work together to improve the detection rate and reduce the false alarm rate, which is the ultimate goal of the vision based pedestrian detection.
Claims8
A pedestrian detection system, comprising:
- a camera module, mounted in a vehicle, and providing a image captured around the vehicle;
- and
- a process module, having two feature capturing modules and a classifier, and receiving and analyzing the image so as to determine whether having a pedestrian in the image, and wherein each feature capturing module adopts histogram of oriented gradients and histogram of gradient of granule feature to capture features of the image.
A pedestrian detection method, comprising:
- capturing a image from a camera module;
- capturing gradient of granule features of the image, and converting the image to a HOGG feature;
- and
- classifying the HOGG feature by a classifier for determining whether having a pedestrian.
