fft变换三个中的一个（站长：三个代码算一个）

这是本人自己编写的可用于256*256大小的图像进行sobel边缘检测的vhd文件，可在QuartusII或MaxplisII下综合和仿真，并在FPGA上测试过。可以进行修改支持其他大小图像的sobel边缘检测，同时还可以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 preparation for the 256* 256 size of the image segmentation Edge Detection vhd document in the next QuartusII or MaxplisII integrated and simulation, and the FPGA tested. Can be adapted to support other size image segmentation edge detection, It can also achieve other modular image processing algorithms, such as Gaussian filtering, smoothing and so on.)
