I have an image of dimensions [835,827]. From this image i have a sub-field image of dimension [137,129].
This sub-field image describes some small circular image with bright intensity inside it as compared to the surrounding.
Now I have decided that if any pixel belongs to that circle, It should lie within 8 pixels in all the direction i.e ,N,W,E,S. If not then the pixel does not belongs to the circle, but rather belongs to the surrounding.
I just want to get extract these small circles with exact pixel, leaving the surrounding. So I found out that the Compass Search will help me in.
Can anyone tell me what is this compass search????
and where will i get it..
thanks

Are you actually trying to make a circular mask with given center and with diameter of 8 pixels?
