【摘要】 提出了一种基于多分辨率小波和二值形态学的边缘检测方法,通过对图像进行多尺度的小波分解,抛弃低频信息来重构小波系数.对重构后的图像利用形态学中的八邻域处理来提取边缘信息.实验结果表明该方法边缘定位准确,对边缘细节的检测效果明显.更多还原

【Abstract】 A new wavelet-based approach for solving the edge detection problem is proposed. The proposed schemes decompose the original image at different scales, discarded wavelet coefficients of the high frequency and preserved the low frequency, and combine the morphologic to obtain better image edge. Simulation results are given to show its efficiency of edge details and location.更多还原
