本系统利用图片的surf特征进行匹配，KD-tree存储特征数据节点，实现相似图片的检索。实现类似于百度的以图搜图功能，结果返回最相似的前十名的图片。-The system uses a picture of the surf feature match, KD-tree storage feature data node, similar image retrieval. Similar to Baidu to search map function returns the results o

基于图像内容的图像检索代码，图像特征为颜色和SIFT特征，返回与查询图像相似的检索结果，程序绝对能够运行。-Content-based image retrieval code image, the image is characterized by color and SIFT features, similar to the query image and return search results, the program is definitely able to run.

Article is devoted to the use of Haar cascades to compare similar images, object tracking problems between adjacent video frames, there is a match on several photographs, image search on the image and other similar problems.
