基于opencv的图像检索系统，提取颜色特征和轮廓特征进行检索-Image retri system based on OpenCV, the extraction of color features and contour feature extraction

This paper proposes a suite of methods to realize high precision pose measurement in 3-D Cartesian space based on a multicamera microscopic vision system. Since it is inefficient to develop a specific image algorithm for each kind of object and t
