Edge following method to find contour point in each bloks of quadtree decomposition

Hi all,

I need some reference of edge following method to find contour point in each bloks of quadtree decomposition.

I already make a coding program that will take intensity value of image in each block of quadtree decomposition.

And the next step is i have to search intensity value which will be contour point in each block using edge following method.

is there anyone knows about edge following method?? please help me ^_^a

Regards,

I'm not sure that makes sense. Each block is "uniform" according to the criteria, so there would be no contours within a block.
