Contrast Stretching in Matlab

LBP算子的实现源代码，可以根据LBP算子来对2张图片的相似度进行比较，值越小，图像越相似。(LBP operator realization of the source code, you can compare LBP operator to the similarity of the two pictures, the smaller the value, the more similar the image.)

基于DCT变换的数字视频水印源程序，在Matlab中可以直接运行(DCT-based digital video watermarking source code in Matlab can be run directly)

医学图像分割当中形变模型方法中的水平集方法实现代码(Medical image segmentation which Morphable Model methods to achieve code level set method)

说明：  使用Harris角点检测器查找特征。再使用SIFT描述符并匹配两个图像之间的特征描述符。使用RANSAC执行单应。最后把图像包起来缝合。(Use Harris corner detector to find features. Sift descriptors are then used to match the feature descriptors between the two images. Use RANSAC to perform single response. Finally, the image is wrapped and stitched.)

图形处理的部分，能进行图像的中值过滤处理(To the median filter for image processing)

这是我研究生期间，用QM Coder做图像和图片压缩的源代码。希望能帮助大家(This is the QM Coder for video/image compression. Hopefully, it will be useful for you. )

该算法为距离-多普勒成像算法，针对场景的多散射点目标录取回波数据，采用匹配滤波的方法实现距离向与方位向的压缩，识别出目标并得到其位置信息。(The algorithm is range Doppler imaging algorithm, aiming at the multi scattering scene target extracting echo data, matched filtering method was used to realize the distance and azimuth compression, identify the target and its location information.)

源码包括了常用的图像处理方法，代码详细，适合初学者(Source code, including the commonly used image processing method, the code in detail, suitable for beginners)

将一张小图片影藏到大图片当中，使用半色调技术，并通过线性变换，调整两幅图像，将小图像影藏到大图像奇数行和列当中，可以调节线性函数的系数，改变影藏效果，改进后的(Will a small picture hidden to the big picture of a shadow of halftone use technology, and through the linear transformation, adjust the two images, the images hidden to big image of an odd number of rows and columns, can adjust the coefficients of the linear function, change the shadow hidden effect)
