edge-detection

问题 I have a binary image [0,1]. I want to use Python to find the edge of the image. I have tried sobel method on the binary but it provides a bad result. I expect the output like the image 回答1: The best way is to apply a 1-pixel morphological erosion, then take the difference between the input image and the result. In pseudo-code: edges = image - erosion(image) 来源： https://stackoverflow.com/questions/54134295/what-is-the-method-for-edge-detection-of-a-binary-image-in-python

问题 I am working on this project where I have to automate the sharpness calculation of an camera taken image without actually looking a the image. I have tried many detection methods, but finally I am going further with Laplacian operator using openCV. Now, the laplacian operator in the openCV returns the image matrix. But, I have to get boolean output whether the image is blurry or not depending upon my threshold. Any link, algorithm or IEEE paper for the same would be helpful. Thanks! 回答1: You
