摘　　要：在图像比对方法中,全搜索算法搜索的精度高,但是由于计算量巨大不适用于实时场合。基于核孔膜防伪标识的图像比对,提出了螺旋型搜索算法,相对于全搜索算法提高了搜索效率,缩短了比对时间。In the method of image contrast, the full-search algorithm to search for the high precision, but is not suitable for real-time occasion because of the great amount of calculation. Based on the Anti-counterfeit marking images conwast of Nuclepore, design of the spiral-search algorithm was proposed, as compared with the full-search algorithm, which improved search efficiency, and shortened the time over.

关 键 词：防伪标识 图像比对 搜索
