Image-filtering

能将一幅灰度图像根据用户自己给定的彩色图像将其对应的转化为真彩色图像。(Gray image can be processed into rgb image.)

bag of words 图像识别算法，斯坦福大学李飞飞实验室做的demo(bag of words)

说明：  针对现有方法存在的隐藏容量低、操作不灵活的缺陷，文章提出了一种基于无损压缩的加密图像可逆 信息隐藏算法。(In view of the defects of low hiding capacity and inflexible operation of the existing methods, this paper proposes a reversible information hiding algorithm for encrypted images based on lossless compression.)

ROF-L2去噪模型，可以有效的去除加性噪声(ROF-L2 denoising model)

图像处理 matlab图像压缩程序， 包括图像压缩的各种技术(image processing image compression in matlab, including technologies in image compression)

图像颜色特征的提取：HSV颜色直方图 描述的是图像的整体颜色情况。本程序采用非均匀量化方法得到36bin的颜色直方图。(Image Color Feature Extraction: HSV color histogram describes the situation of the image' s overall color. This procedure using non-uniform quantization method the color histogram 36bin.)

直方图均衡化的实现，RGB直方图均衡化，直方图归一化。(Histogram equalization to achieve, RGB histogram equalization, histogram normalization.)

说明：  canny算子边缘提取。用matlab编写，并有详细的解释。(use matlab to canny edge detection operator,with a detailed explanation.)
