Magic Wand Implementation

[Soumyadip Rakshit]

Hi there,

I am trying to implement a function similar to the 'magic wand' tool in
Photoshop to find the boundary of similar-graylevel area starting from a
point within it. So basically I want to start from a pixel in the region
which has a very similar gray level not varying by more than 5 gray values
and find its ends in all directions.

Could you please tell me where I can find such an implementation or an
efficient algorithm to do the same.

Thanks a ton,
Soumyadip.
