| 摘 要： | 为了在准确检测边缘的同时有效地抑制噪声,提出了结合信号配准技术的小波多尺度边缘检测方法。该方法首先基于小波变换的特点设计小波多尺度边缘检测算法检测图像边缘;而后结合信号配准技术将不连续的边缘连接为完整的边缘轮廓,减弱由噪声或干扰造成的影响。试验结果表明:该方法不仅能准确检测出清晰连续的边缘图像,而且能有效抑制噪声,是边缘检测的实用方法。

| Abstract: | In order to detect edges correctly while noise can be effectively restrained,wavelet multi-scale edge detection method with signal registration technology was proposed.The method firstly was used to design wavelet multi-scale edge detection algorithm to detect image edges based on the characteristic of wavelet transformation.Then,the discontinuous edges were connected into a contour line with signal registration technology to weaken the influence of noise or disturbance.The experimental results show that the method can not only precisely detect clear and continuous edge images,but also can effectively restrain noise,and is a practical edge detection algorithm. |
