I have such image:
It is a binary image, I mean the pixel value is 0
or 255
, but now, I hope to replace every pixel value with its distance from self to the image edge, but I don't care the distance is shortest or not. Such as the following red pixel, which have two or more paths to image edges. We can use any distance to replace its pixel value.
Is there any efficient method can implement this target in opencv?
