摘要

基于Zernike图像矩的理想边缘模型

深入研究了方向角模型与亚像素判据间的关系。利用Zernike矩定义及其旋转不变特性

提出一种新的基于4阶方向角的Zernike矩亚像素边缘检测算子。为了提高边缘算子定位速度

首先基于9×9尺寸模板对Zernike图像矩0～4阶正交复数多项式进行了计算

推导出基于4阶方向角的边缘检测算子参数模型。最后将边缘算子应用在理想图像与实际图像上

检测结果表明:相比于传统的Zernike矩算子

基于4阶方向角的边缘检测算子具有更高的检测精度。

Abstract

Based on Zernike image moments edge model

relationship between direction angle model and sub-pixel criterion is studied deeply.A new edge detecting operator method based on 4-order direction angle is proposed

by using Zernike moments definition and its rotation invariance.In order to improve positioning speed of edge operator

the orthogonal complex polynomial is computed from 0 to 4 orders of the Zernike moments based on 9×9 mask

the edge detecting operator parameter model is deduced.Finally

edge operator is applied to ideal image and real image

test results show that the edge detecting operator based on 4-order direction angle has higher detecting precision compared with traditional method.
