摘要
提出了一种基于联合变换相关的光学小波实时图像边缘增强的方法.选用Mexican-hat小波,利用小波函数的多分辨率特性,用联合变换相关的方法实现了缩放后的小波母函数与待识别图像函数的互相关(即边缘增强图像),得到了较满意的实验结果.
An optical wavelet transform for real-time image edge extraction system based on joint transform correlation ( JTC) was proposed in this paper. By taking advantage of the multiresolution characteristic of the wavelet function and by means of joint transform correlation, the Xcorr of the shrunk or zoomed wavelet generating function and image function by using Mexican-hat wavelet was implemented in real time. The experimental results are given.
