摘要：

A novel moment-based method for sub-pixel edge location is proposed. Based on coarse edge-location by SOBEL operator, the geometric information of the target is used to reduce the number of moment-template to only one, which can largely save the time. Experimental results demonstrate that the proposed method is effective with more robustness, higher precision and speed. (c) 2010 Elsevier B.V. All rights reserved.
