hough 检测直线 算法简单 是静态图像中检测直线的快速实现( Hough detecting )

很好用的肤色分割模型，在YCBCR颜色空间内分割，经过开运算和闭运算，取得很好的结果(Good use of color segmentation model, YCBCR color space segmentation, after opening operation and closing operation, and achieved good results)

对视频中的几帧进行移动目标检测，着重标记出移动目标。(Moving targets are detected for several frames in the video, with emphasis on the moving target.)

数字水印程序，包括多分辨嵌入水印、提取水印程序，盲水印嵌入、提取程序，以及滤波攻击和JPEG攻击程序，PSNR和相似度计算公式（MATLAB）(digital watermarking procedures, including multiresolution embedded watermark, watermark extraction procedure, blind watermark embedding and extraction procedures, Filtering and attack and attack JPEG procedures, PSNR and the similarity calculation formula (MATLAB))

在这个程序中，我们读取两张图像，进行特征匹配。然后根据匹配得到的特征，计算相机运动以及特征点的位置。这是一个典型的Bundle Adjustment，我们用g2o进行优化。

算法的改进方案，总共有10种，基于质心加权的算法改进(Algorithm improvement program, a total of 10 species, based on the weighted centroid algorithm improvements)

主要思想是用meanshift算法跟踪目标，拖动矩形框选择目标模板，meanshift自动跟踪 本程序的主要缺陷体现在帧差法自动识别目标，这部分功能与上一个功能独立，可用可不用，用于自动识别目标，效果不是很好，主要体现在对图像视频的要求是 背景（目标以外的所有事物）不能动(The main idea is to use meanshift algorithm to track the target and drag a rectangle to select the target template, meanshift automatic tracking The main drawback of the program is reflected in the frame difference method automatically identifies the target, which is part of the function and one function independently, may or may not, be used to automatically identify the target, the effect is not very good, mainly reflected in the requirements of the video image is the background (target All things outside) can not move)

SPIHT的图像压缩算法源代码。可以针对128×128的图像进行压缩(SPIHT image compression algorithm source code. 128 × 128 image compression)

数字图像处理课程期终项目，对图像进行放大，并进行滤波，达到一定的信噪比。(The final project of the digital image processing lesson, which is programmed for enlarging a image into demanding size.)
