视频水印matlab源码，此为第五个压缩包，在水印领域的爱好者可以下载作为参考(Video Watermarking Matlab source, which is the fifth-compressed, Watermark in the field of lovers can download as a reference)

说明：  对指定的一幅含有多个目标的灰度图像，进行基于阈值的图像分割处理，对结果图像进行基于数学形态学的后处理设计，以得到更理想的目标区域。最后对结果图像进行区域标记（以颜色区分不同区域）并提取目标个数、各目标区域的面积、圆形度等特征。(The gray image with multiple targets is segmented based on threshold, and the result image is designed based on mathematical morphology to get a better target area. Finally, we mark the region of the result image (distinguish different regions by color) and extract the number of targets, the area of each target region, roundness and other features.)

用哈夫曼算法对图像进行压缩， 1.颜色模式转换及采样； 2．DCT变换（离散余弦变换）； 3．量化；4．编码（有算术编码和哈夫曼编码两种，这里采用哈夫曼编码）

说明：  最新的ROI(Region of Interest)算法，不再像传统算法那样只能画出一个圆或者一个长方形。(The latest ROI (Region of Interest) algorithm, is no longer like the traditional algorithms can only be drawn as a circle or a rectangle.)

KSVD&&OMP处理图像的程序，有演示效果(KSVD&&OMP )

采用曲率的方法，等间隔三点的大小计算夹角的大小，根据阈值标记指尖指根区域。(Curvature of the methods used, such as the size of three intervals calculated the size of the angle, according to the threshold refers to the root area marked fingertips.)

基于svd的数字水印，信噪比比较高(Svd based digital watermarking, can also signal to noise ratio is relatively high)

说明：  GOME-2数据反演叶绿素荧光算法代码，添加文件为GOME-2 level 1b级数据时，得到的Fs数组即为反演结果(Code of chlorophyll fluorescence algorithm retrieved from GOME-2 data)

Tamura纹理特征提取及应用的matlab代码，附有介绍绍Tamura纹理的文献和测试用图片。，已通过测试。 (Tamura texture feature extraction and application of the Matlab code, accompanied by Shao Tamura texture literature and test pictures. , Has been tested.)

功能简单的截图，可以像qq那样截图，并有图片处理功能(Simple screenshots, like QQ screenshots, and image processing capabilities)
