训练图片中检测到的目标，检测特征是基于梯度方向直方图(training target)

说明：  图像颜色显著性，包含颜色直方图和颜色矩，是颜色显著性评价的重要内容(Image Color Salience)

Moravec算子，实现对数字图像处理中的点特征提取，可用于图像拼接，特征提取，三维点生成(Moravec operator, the realization of digital image processing in point feature extraction, can be used for image stitching, feature extraction, 3D point generation)

基于梯度相似度的图像质量评价方法，发表在2012年TIP国际期刊上(A. Liu, W. Lin, M. Narwaria, “Image Quality Assessment Based on Gradient Similarity,” IEEE Transactions on Image Processing, vol. 21(4), pp. 1500-1512, 2012.)

基于区域的主动轮廓模型算法，是论文《Active Contours Without Edges》的VC算法实现(Region-based active contour model algorithm, for the paper " Active Contours Without Edges" of the VC algorithm)

说明：  以图搜图，深度学习，采用vgg16,对应文件夹放入图片即可使用(image_retrieval_platform-master)

说明：  基于DCT和DWT的数字水印技术，可对图像进行DCT和DWT变换(Digital watermarking technology based on DCT and DWT can transform image into DCT and DWT)

本代码是使用matlab编写的harr特征的代码，值得大家研究和参考(This code is the use of matlab prepared harr characteristics of the code, it is worth study and reference)

张正友标定法中计算内参的方法，经典原文资料(calculate Intrinsics zhang s method)

多尺度的光谱图像分割，有对应的论文和matlab及c++代码(Multiscale spectral image segmentation, there are papers and the corresponding matlab and c++ code)
