Research of Image Pre-processing Algorithm Based on FPGA

摘要

How to design a low-cost , reliable and real-time target recognition system with large amount ofdata has become a hot topic in the area of image processing .However, Edge detection has played animportant role in target recognition system. The threshold of traditional canny edge detection algorithmmust be setting by human, and has a large number of calculations. In order to overcome the shortcomingsof the traditional Canny algorithm, proposing an adaptive threshold edge detection algorithm, andrealizing it by hardware. This paper will introduce the implementation of the common low-level imageprocessing algorithm in the FPGA, including color space convert module , edge extraction algorithmsmodule , Hough transform module .The results of the experiment indicate that to realize the large amountof calculation of image processing by FPGA hardware logic, not only improves the effect of imageprocessing, but also has high real-time!
