Region Growing

hi all

i'm trying to make a region growing segmentation for my project , can anyone please help me writng the code

the algorithm is as follows:

1. seed the first pixel(seed) manually
2. get the value of the seed
3. compare it with its 4-neighbors or 8-neighbors(i dont know which is better)
4. if the neighbors have the same value then they are in region
5. compare these neighbors with there other neighbors and so on until it finds a boundary, then stop

thanks a lot

This is not a big problem, I think, you can use GetPixel to obtain the value of the given point and compare it with the neighbors, you don't give clear about which language you want to write, c++ or vb? or use MFC?

"if the neighbors have the same value then they are in region": I suppose your image is thresholded into binary values. Otherwise, this is not the correct way to do this. If the image is in its original state, then you will have to use other statistics (than gray value), like texture and moments.

have you got source code for this???
i need this source code for my final task
