Flood filling algorithm

WebThe Flood Fill algorithm is also sometimes called Seed Fill: you plant a seed (the pixel where you start), and, recursively, more and more seeds are planted around the original seed if those pixels have the correct color. Each new seed is responsible for coloring the pixel at its position, and testing for new pixels around it WebThe imfill function performs a flood-fill operation on binary and grayscale images. This operation can be useful in removing irrelevant artifacts from images. For binary images, imfill changes connected background pixels ( 0 s) to foreground pixels ( 1 s), stopping when it reaches object boundaries.

WebTo solve this problem, we can use a recursive algorithm that performs a flood fill operation starting from each white region. The basic idea is to start from a point in a white region, change its color to the desired color (red or blue), and then recursively call the flood fill function for each neighboring point that is also white.
