凸多边形检测和显示--先把图像中的显著区域提取出来，然后用最小凸多边形囊括显著区域，并把凸多边形显示出来(Convex polygon detection and show- first images extracted significant area, and then use the smallest convex polygon covering a significant area, and the convex polygon displayed)

基于非局部图像去噪模型的遥感图像融合的变分方法。该变分方法采用梯度下降法。(Variational method of remote sensing images nonlocal image denoising model fusion. The variational method using gradient descent.)

数字图像处理中图像的增强方便的源代码，包括图像灰度修正，图像的平滑，中值滤波，图像的锐化，伪彩色和假彩色的增强等(Digital image processing image enhancement convenient source code, including the gray correction, image smoothing, median filtering, image sharpening, pseudo-color and false color enhancement, etc.)

直方图拉伸是通过对比度拉伸对直方图进行调整，从而“扩大”前景和背景灰度的差别，以达到增强对比度的目的(Histogram stretching histogram is adjusted by contrast stretching, thereby " expand" the difference between the foreground and background of gray, in order to achieve the purpose of enhancing the contrast)

说明：  有关图像处理中的图像校正，MATLAB，亲测可行(ImageRegistration matlab)

完成对彩色图像的灰阶变化和噪声滤除处理，并通过数学计算完成对ISNR的求解。(Complete color image gray-scale changes and filter out noise, and completed ISNR solving through mathematical calculations.)

processing编写的圆形速度运动代码(processing written in the circular speed of movement code)

说明：  脆弱性数字水印能为多媒体内容完整性认证和篡改检测提供有效的解决方案。该文对用于图像认证的脆弱性数字水印技术的研究 现状、一般原理、基本特征、典型算法进行了综述(The vulnerability of digital watermark for the integrity of multimedia content authentication and tamper detection to provide an effective solution. The image authentication for the vulnerability of digital watermarking technology, research, general principles, basic features, typical algorithms are reviewed)

针对高分辨率遥感图像进行的道路提取，效果还行。(The road extraction for high resolution remote sensing images is good.)

本程序实现了两种误差扩散算法，分别用Sierra扩散滤波器和stenenson扩散滤波器，实现了比Floy_stein更好的误差扩散半色调效果。(This procedure implements two error diffusion algorithm, respectively Sierra diffusion filters and stenenson diffusion filter, to achieve better than Floy_stein error diffusion halftone effects.)
