Description: When developing web-pages or graphics we frequently need a tool that will give us the RGB value of the color of a particular region in some other application s window. An example could be that you need to know the background color of a JPG image so that you can use the same color for the background of the webpage on which you will display the image. ColorFinder comes in handy exactly for this. You can use this tool to pick color from any pixel on the desktop.

Description: 该软件支持jpg，gif、png图片格式，大致有下列功能：
V 0.1 版：
1. 图像放大、缩小、复制、打印、获取当前图像任意位置颜色信息。
2. 显示图像灰度直方图。
3. 灰度统计：图像宽度、高度、最小灰度、最大灰度、灰度均值 Mean、灰度方差 Variance、标准差、偏态 Skewness、峰度系数 Kurtosis、熵 (Entropy)。
4. RGB三原色分离、RGB图转灰度图、灰度均衡、图像可调阈值二值化、图像反色。
5. 图像可调阈值边缘检测：Robert算子；Prewit算子；Sobel算子；Kirsch算子
6. 图像Huffman编码。
7. 调色板、屏幕捕捉、屏幕取色、屏幕上任意两点距离的测量。
-The software supports jpg, gif, png image format, generally have the following functions: V 0.1 version: 1. The image to enlarge, shrink, copy, print, anywhere access to the current image color information. 2. Histogram display images. 3. Grayscale statistics: image width, height, minimum gray level, the largest gray, gray Mean Mean, gray variance Variance, standard deviation, skewness Skewness, kurtosis coefficient of Kurtosis, entropy (Entropy). 4. RGB RGB Separation, RGB to grayscale map, gray balance, adjustable threshold image binarization, image anti-color. 5. Image adjustable threshold edge detection: Robert operator Prewit operator Sobel operator Kirsch operator 6. Image Huffman coding. 7. Palettes, screen capture, get color screen, the screen distance between any two measurements.

Description: 感觉是国内讲的最透彻的图象处理处理中文讲义（国外的做的好的多），深入浅出，发人深思！特别适合计算机视觉领域研究的新手上路！
1、讲义包括04版和06版，新版本更爽。
2、还有cv领域的前研与应用的介绍。
3、实验报告介绍vi软件的使用（一个简单的图象格式转换转件），vi可读取bmp，jpg,tif,png,gif,rgb,cel,tga,dat,转换输出bmp,jpg,tif,png,dat。
让我们在cv领域中畅想与飞翔！-Feeling is that the domestic stresses the most thorough treatment of the images deal with Chinese notes (to do good abroad and more), in layman
