美国ACM SIGGRAPH的计算几何图形代码精华，连载3

于傅里叶变换的图像加密技术研究 具体是将一幅图像用 fft 变换到频域 在频域中进行加密 我考虑的是通过随机相位来加密的方法，请问用matlab怎样实现 加密后在通过 ifft 得到加密后的图象 -Fourier transform in the image encryption technology to study the details of an image is to use fft transformed to the frequency domain in the frequency domain I consider encryption is through random-phase approach to encryption, Will the use of Matlab how to achieve the adoption of encryption ifft be encrypted images

转载的一个对图像进行简单处理的程序。挺好的，建议大家看一看。-Reproduced in a simple image processing procedures. Quite good, it is recommended you take a look at.

可实现与graph-cuts算法相似的图像分割效果. 他借用了生物形态学知识，将每一个像素视为一个细胞，这些细胞可能是前景，背景，或其他。这些细胞依据其灰度竞争获得生长，由此获得分割。-This algorithm is presented as an alternative to graph-cuts. The operation is very simple, and can be thought of with a biological metaphor: Imagine each image pixel is a "cell" of a certain type. These cells can be foreground, background, undefined, or others. As the algorithm proceeds, these cells compete to dominate the image domain. The ability of the cells to spread is related to the image pixel intensity

在编程过程中经常需要用到的算法，语言：C＋＋。-the programming process often need to use the algorithms, languages : C++.

snake模型的C源码，采用欧拉方程求解模型的能量最小值，实现了经典的活动轮廓模型-snake 模 would like to have 的 C 码, 采 sputum 欧拉方程求解模 would like ghosts from the 的能量 Chiating Jun 了经典的活动轮廓模 would like to

本科数字图像处理试验程序2，包括图像锐化分割等-Undergraduate digital image processing, two testing procedures, including image sharpening segmentation

一个关于V C + + 的教程，很不错的，主要用于图像处理-A VC++ The tutorial, very good, mainly for image processing

自己编写的菜单小程序，水平有限．交流第一．多多指正．-own small menu prepared by the procedure is limited. The first exchange. Lot correction.

该watershed算法可以实现图像的基于生长法的边界提取功能-The watershed algorithm can realize the image-based growth method of edge extraction function

JPEF格式的图像处理，我会相继上传多种格式的图像处理源码，希望共同探讨。-JPEF format image processing, I will have upload multiple format of image processing source, hoping to explore.
