| 摘 要： | 针对多聚焦度分析和部分有损图像分析中难以提前完整边缘信息的问题，提出了一种基于小波域图像融合的边缘检测算法。它是在小波变换多分辨率分析的基础上，运用图像融合及图像增强理论，使得小波子带边缘信息量最大化，再运用经典的Canny算子边缘检测算法最终实现图像边缘的检测。

| Abstract: | An edge detection algorithm based on the wavelet domain image fusion is put forward in view of the problems in multi-focus analysis and lossy image analysis difficult to advance complete edge information.Based on multi-resolution analysis of wavelet transform,the theory of image fusion and enhancement is applied,to maximize the information amount of wavelet sub-band edge.Then,the classic Canny operator edge detection algorithm is used in final image edge detection. |
