本程序可实现维纳滤波，可应用于反褶积等反问题的求解过程中，是非常简单实用的(This program can be realized Wiener filter can be applied to deconvolution inverse problems and the process is very simple and practical)

2d convolution on image

将RGB格式的图像转换为灰度模式。 使用TI C6748 DSP 在CCS5.5下运行(convert RGB image to grey code. use in C6748DSP. written under CCS5.5. )

matlab生成的fig图纸转换为DXF文件(Converting fig drawings generated by MATLAB into DXF files)

各向异性扩散相干斑降噪，可以在增强边缘的同时滤出噪声，效果很好！(Anisotropic diffusion, coherent noise can enhance the edge of the filter out the noise at the same time, the effect is very good!)

说明：  ① 打开图片文件； ② 实现图像的放大、缩小功能； ③ 实现图像的黑白处理。 (black setting open file)

本代码可以实现图像的维纳滤波，经过调试无错误，对于学习图像处理有较好帮助。(This code can achieve the image filtering, error-free through the debugging, better for learning image processing help.)

软硬阈值及软硬阈值折中法对bumps信号去噪，另外包含信噪比以及均方误差的求解。(Soft and hard threshold and soft and hard threshold compromise the bumps signal denoising, the other contains the signal to noise ratio and mean square error to solve.)

求图像的二维直方图，产生共生矩阵，可以比较像素点分布的是否均匀。(Two dimensional histogram for image, the co-occurrence matrix, can compare the pixel distribution is uniform.)

经典数字水印算法，包括GUI实现 可直接运行(classic digital watermarking algorithm, including the realization of GUI can run)
