Introduces color feature extraction and matching algorithms in content-based image retrieval, such as weighted Euclidean-distance, weighted centre distance, histogram intersection algorithm, etc.
A colorimage registration model within the framework of abstract matching flow is proposed to deal with the problem of serious color difference between registered images.
在抽象匹配流框架下，构造能够克服大色差问题的彩色图像配准模型。

An algorithm based on area search matching was proposed. The algorithm used color information of measure points to find image grids and to measure the displacement in similar material experiment.
