I have a grayscale image and location of some pixels from where i have to check whether the pixels connected to it have intensity greater than the given threshold .
There is a seperate threshold for every given starting pixel.
for a given pixel location p[i j] wih a threshold value 't' , I have to start at the pixel location [i j] in the grayscale image and check if the pixels connected to it (in 8 directions) have intensity greater than threshold 't'.If yes,then the process needs to be continued with that pixels too until no more pixels with intensity greater than threshold are found.
The process should start simultaneously from all given pixel locations in the image.
I need a logical array of 0s and 1s as result,the ones whose intensity are greater than t will be marked as 1 and the process will be continued till connected pixels don't have intensity greater than 't'.
Can somebody help me how to do this?
