Title: Reconfigurable Hardware Implementation of a Fast and Efficient Motion Detection Algorithm
Keywords: Motion detection. Real-time implementation. Reconfigurable hardware
Abstract: In this paper,we propose a fast motion detection algorithm based on a multi-modal distribution to detect the moving objects in image sequence of size 768 x 576 pixels taken from a static camera with a small number of calculations to achieve a high frame rate.We show that the elapsed time per frame is reduced by applying our algorithm.Two major features make our algorithm a good candidate for hardware implementation.First,it is primarily composed of linear operations that are easily implemented in hardware. Linear operations can be represented efficiently in terms of the number of logic blocks required,and can be computed in one clock cycle.Second,there is no iteration for any explicit coarse-to-fine control strategy.This property makes the real time flow of data possible through the hardware.This paper describes also an FPGAbased implementation of the proposed motion detection algorithm at a very high frame rate that reaches to 1130 frames per second in a single FPGA chip.
