Abstract: Aiming at regularity and repeatability of image texture and inconsistent characteristic of initial texture distribution, this paper achieves registration according to the texture feature registration algorithm of VE4000 detection system. This algorithm designs single template by itself, then makes cutting and splicing technology for single template in order to realize the goal of image registration. But the registration effect of this algorithm is relatively poor, so this paper proposes an improved texture feature registration algorithm that designs afresh template, splices for generating standardized referenced image and makes matching and cutting for referenced image to obtain different registration images. Experimental results show that, the improved registration algorithm based on texture feature having shorter running time and smaller registration error, can commendably meet registration requirements of defect detection.
