WebErosion is the process of removing white pixels from the boundaries in an image. You can achieve this in a binary image by using ImageFilter.MinFilter(3) as an argument for the .filter() method. This filter replaces the value of a pixel with the minimum value of the nine pixels in the 3x3 array centered around the pixel. In a binary image, this ... WebBinary erosion is a mathematical morphology operation used for image processing. Parameters: inputarray_like. Binary image to be eroded. Non-zero (True) elements form the subset to be eroded. structurearray_like, optional. Structuring element used for the erosion. Non-zero elements are considered True.
