基于堆栈的图像分割算法，速度较普通区域生长法更快(Stack-based image segmentation algorithm, region growing faster than the ordinary method faster)

基于区域方差取大的图像融合算法 代码编写经典(Based on the regional variance max of the image fusion algorithm )

Mean shift algorithm for segmentation and smoothing images. the example images are horses.

B样条曲面方法，通过b样条曲面的拟合得到图像的背景，减去背景图像就能得到重要内容的图像，除去了背景对图像内容的干扰，也可解决光照不均的问题(algorithms for cytoplasm segmentation of fluorescence labelled cells)

一些基本的图像处理算法的matlab实现，包括边缘提取和roc分析等(some basic image processing algorithms to achieve Matlab, including edge detection and analysis roc)

说明：   针对雾天下拍摄图像的退化现象，远景部分是一块灰度分布比较集中且接近天空亮度的区域，而近景部分可以分辨，其灰度分布比较分散。提出了一种基于遗传算法阈值分割的雾天图像增强方法；该方法首先用遗传算法求出近远景的分割阈值将图像分割[1]出来，然后对两个部分分别进行清晰化处理。(make the picture clear)

说明：  出一个基于扩散与位平面Amold映射相结合的彩色图像置乱，以及采用Chen系统产 生的混沌序列加密的图像加密算法。(A combination of diffusion bit plane Amold mapping based color image scrambling, and Chen system chaotic sequence encryption image encryption algorithm.)

重要的纹理分割分类基础程序，可以进行更深入的探讨和优化，应用于遥感影像中。(Important basis for classification of texture segmentation procedure can be carried out more in-depth exploration and optimization, application of remote sensing images.)

说明：  本程序基于Matlab,初步实现图像增强的基本操作,实现 图像明暗度调整， 图像旋转，更改颜色显示方式，直接灰度调整，图像求反，动态范围压缩，显示原始图像直方图，直方图均衡化，滤波增强等功能(This procedure based on Matlab, the initial realization of the basic operation of image enhancement, image brightness adjustment, image rotation, change the color display, direct gray-scale adjustment, for anti-image, dynamic range compression, display the original image histogram, histogram equalization , enhanced features such as filtering)
