A method to detect new objects in a scene by comparing an input query image and a movie database captured beforehand is proposed. Our method is based on both feature point matching and edge matching. First, we select the most matched movie from t

通过比较两幅图像直接的直方图来测量两幅图像之间的相似性。因为直方图比较是基于逐个容器进行的比较，不考虑相邻容器的影像，顾比较之前对查询图像和输入图像减少颜色空间。-Direct histogram similarity measure between two images by comparing the two images. Because histograms are more individually based on container, without regard to the i

该文件是用于图像检索的demo，主要利用sift描述子提取特征进行匹配，在“Query by example” 数据库中运行效果良好。(The file is used for image retrieval demo, mainly using sift descr iptor to extract features and match it in the "Query by example" database.)
