Abstract
In this paper, we propose the architecture of high-performance HOG feature extractor circuit for the driver assistance system. We have proposed the simplified hardwired methods for the square root of the gradient calculation and the division operation of the block normalization. Our HOG feature extractor circuit can process 37 frames per seconds for 640×480 VGA images in real-time.
