关于图像分割、区域分离和合并的matlab程序(On image segmentation, region separation and merger procedures matlab)

该上传的256张CT图片是高质量的DICOME格式人类头骨的连续序列切片图，可直接用于医学三维重建或体绘制。(The upload of 256 CT images are of high quality DICOME form a continuous sequence of the human skull slice diagram can be directly used in medical 3D reconstruction or volume rendering.)

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.)

SSIM函数。一种衡量两幅图像相似度的新指标，其值越大越好，最大为1。(SSIM function. A measure of image similarity two new indicators, the greater its value better, a maximum of 1.)

粒子滤波算法比较,不同的建议分布下，粒子滤波的性能差异，包括精度与时间(the comparision)

说明：  该代码的主要功能是图像边缘检测，利用霍夫变换确定圆的位置，并进行缺陷定位着色等操作(The main function of the code is image edge detection, using HOF transform to determine the location of the circle, and the location of defects such as coloring operations)

color image watermarking with color

说明：  基础图像处理语言，RGB各图层提取，量化图像，lena典型案例代码。(Basic image processing language, RGB layer extraction, quantization image, Lena typical case code.)

计算PSNR值，一个不错的算法，值得看一下(Calculation of PSNR value, a good algorithm, it is worth a look)
