边缘检测算法的FPGA实现

Implementation of Edge Detection Algorithm in FPGA

边缘检测算法是最常见的图像处理算法.分析了Prewitt算子和Sobel算子两种边缘检测算法的原理,利用DSP Builder工具在MATLAB/Simulink下完成了这两种算子的图像边缘检测算法的设计,并将该设计直接在FPGA中实现.利用FPGA的并行处理能力,大大缩短了图像处理所需的时间.

Edge detection algorithm is the most common image processing algorithms. The principles of two kinds of edge detection algorithm--Prewitt operator and Sobel operator are analyzed. The DSP design of the image edge detection algorithm is completed by using DSP Builder tool in a friendly environment MATLAB/Simulink. And then the design is implemented directly in FPGA. It can shorten the image processing time with the capability of parallel process by using FPGA to process image.
