Analyzing of the Characteristic of Image Edge

WU Xiao Bo (Dept.of Automation of Logistical Engineering University,Chongqing 400041)  
The technology of image measurement is a newly rising technology in the domain of the measurement recent year.It is very important to locate the position of image edge precisely using the method of image measurement.First,in this paper,we describe briefly the image measuring system,then analyze the characteristic of image edge and point out the gradient is the maximum at the characteristic points of edge.This provides the theoretic foundation for subpixel edge detection.
