摘要
In order to overcome the disadvantages of time consuming and high computational cost in spatial moment, an improved sub-pixel edge detection algorithm based on spatial moment is proposed. Firstly, region of interest and Canny operator is used to reduce the number of edge points in the moment template operation. Then a constraint is set up by using the space moment characteristic of the edge to determine whether the pixel is the edge point. Finally, Using linear equations instead of nonlinear equations to obtain edge parameter. Only a moment template is required to participate in the operation. The experimental results show that the proposed algorithm is simple, accurate and timesaving. © 2016, UK Simulation Society. All rights reserved.
