基于尺度空域相关性的图像边缘检测

根据小波分析多尺度空间的相关性,在模极大值边缘检测的基础上提出一种新的图像边缘检测方法.该方法不需要对图像进行预处理就能较精确的检测出图像的边缘.取相邻尺度的小波系数相乘进行相关计算,在抑制噪声的同时提高边缘的定位精度.方法快捷,算法简便,克服了直接对图像进行模极大值边缘检测造成的误差.实验结果表明,该方法得到了满意的效果.

Edge detection of image based on scale spatially correlation

According to the correlation in the multi-scale space of wavelet analysis,a new method about edge detection based on wavelet transform maxima,this method can detect the edge exactly without preprocessing is proposed,make the correlation calculation between the adjacent wavelet coefficient,overcome the inaccuracy during the edge detection on the basis of wavelet transform maxima,at the time of restricting noise increase the accuracy of edge.The experimental results show that this method is very satisfactory.
