It is possible that the different object eigenvectors is similar or the same object eigenvectors is different under scaling  shifting  rotation if eigenvectors can not be chosen appropriately. In order to solve this problem  the image is edged  the membership function is reconstructed and a new threshold segmentation method based on fuzzy theory is proposed to get the binary image. Moment invariant of binary image is extracted and normalized. Some time moment invariant is too small to calculate effectively so logarithm of moment invariant is taken as input eigenvectors of BP network. The experimental results demonstrate that the proposed approach could recognize the object effectively  correctly and quickly.   Parameters analysis of few-modes optical fiber evanescent absorption sensor - art. no. 603208 会议论文  OAI收割 2006 作者:  Li F. 收藏  |  浏览/下载：6/0  |  提交时间：2013/03/28
