利用阶跃滤波器实现二值图像边缘增强
Edge Enhancement of Binary Image Using Step filter
摘要
介绍利用阶跃滤波器实现二值图像边缘增强的光学方法。阶跃滤波器在频域的适当的位移(偏置)即可以改善输出图像的衬底,也能改善其轮廓视锐度,从而有利于图像边缘的检测。
Abstract
This paper deals with a optical method of edge enhancement of the binary image using the step filter. Properly shifting the filter on the frequency region can improve the contrast and the contour acuity of the output image. It is profitable for edge detection.
