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 n

Implementation of Image Processing Algorithms in FPGA Hardware.

在图像实时处理的过程中，下层图像预处理的数据量大，运算简单，但是要求运算速率高，可以用FPGA硬件来处理，上层所处理的数据量少，算法结构复杂，适于运算速度快，寻址灵活的DSP数字信号处理器进行处理。该系统充分发挥了FPGA和DSP各自的优势，能更好地提高图像处理的实时性，降低成本。 -Real-time processing in the image process, the lower the amount of data preprocessing, simple operation,

Image compression is one of the prominent topics in image processing that plays a very important role in reducing image size for real-time transmission and storage. Many of the standards recommend the use of DWT for image compression. The compu
