这是我本人自己开发的可用于256*256大小的图像进行sobel边缘检测的vhd文件，可在QuartusII或MaxplisII下综合与与仿真，并在FPGA上测试过。能进行修改支持其他大小图像的sobeel边缘检测，同时还能实现其它的图像模块化处理算法，例如高斯滤波，平滑等。 (This is my own development vhd file, can be used for 256* 256 size image sobel edge detection under QuartusII or MaxplisII synthesis and with simulation, and tested on FPGA. Can be modified to support other sobeel size image edge detection, while still achieving other image the modular processing algorithms, such as Gaussian filtering and smoothing.)
