I have been trying to come up with a region growing algorithm but I'm not sure that I fully understood the region growing segmentation method (for gray-scale images). Please correct me if I'm wrong:
- I start from a seed point chosen by me (brightest value that fits the wanted region ,because the segmentation target is a girl's face).
- From the location of that seed point I compare the adjacent points and if their value is between a given threshold and the seed point value then I add it to the seed point map(matrix).
- I must try all the valid seed points for adjacent neighbors. The result is just plotting the seed point map (matrix).
