中文摘要：

提出一种新的Harris与改进SIFT算法相结合的算法。首先用Harris算子提取图像的角点作为特征点，然后采用基于同心圆形窗口的64维向量有效地表征一个特征点．实验结果说明，算法在保持很好匹配率的同时能降低计算复杂度．

英文摘要：

A new algorithm based on Harris and the improved algorithm SIFT is developed. In the new algorithm, the comer produced by Harris algorithms are used as the feature points and vectors of 64 di- mensions based on a circular window are used to represent the feature points. The experimental results show that the new algorithm reduce the matching time and maintain a relatively good matching preci- sion at the same time.
