quaternion

一个博士写的基于PDE图象处理的开发包。很有用处，对做PDE图象处理的人是个福音。(write a PDE-based image processing development package. Useful to do image processing PDE is the Gospel.)

说明：  一种改进的均值聚类算法，能很好的利用与图像分割技术(k-means cluster)

数字图像处理实验-图像处理-含实验题目及源代码(Pseudo-Color Image Processing (a) Implement Fig. 6.23, with the characteristic that you can specify two ranges of gray-level values for the input image and your program will output an RGB image whose pixels have a specified color corresponding to one range of gray levels in the input image, and the remaining pixels in the RGB image have the same shade of gray as they had in the input image. You can limit the input colors to all the colors in Fig. 6.4(a). (b) Download the image in Fig. 1.10(4) and process it with your program so that the river appears yellow and the rest of the pixels are the same shades of gray as in the input image. It is acceptable to have isolated specs in the image that also appear yellow, but these should be kept as few as possible by proper choice of the two gray-level bands that you input into your program.)

亮度代表了图像的明暗程度，颜色代表了图像的色度，它包含了色调和饱和度。这个代码可以自动对这三个参数进行调整。(Brightness represents the degree of image brightness, color represents the color image, which includes hue and saturation. This code can be automatically adjusted to the three parameters.)

说明：  可以实现背景和目标的分离,效果还是不错的(about matlab programe)

数字图像处理中的编码技术。本程序对输入的图像进行哈夫曼huffman编码，显示原图像的熵、编码后的平均码字长度、并能够根据编码重建出图像。本程序使用C++混合编程，已经编译生成了Matlab库文件，无需再与C++链接。程序包括源程序和源图像，以及编码后的结果图像。(Encoding digital image processing technology. The procedure of the input image Huffman huffman coding to show the original image entropy, encoded average code length, and be able to reconstruct the image according to encoding. The program uses C++ mixed programming, has compiled a Matlab library files generated, do not need to link with C++. Programs include source code and source images, and encoding the results of the image.)
