This document describes a FPGA implementation of an optical flow correlation based detection method which is very fast (with low accuracy) and allows near real time applications (6 frames/second) on standard computing hardware. It manages the motion estimation problem with a speed restriction, obtained from an image down sample process, that yields image(More)

This paper describes an electronic system designed for real-time vision applications. The system will allow the development of low-complexity tasks, such as obstacle detection, at very high frequencies. This makes it useful for robotic applications and control systems in real time (up to 25 images per second). Its design has taken into account low-cost and(More)
