Simple single-seeded region growing



24 Feb 2012 (Updated )

Segmentation by growing a region from user defined seed point, using intensity mean measure.

File Information

Simple and efficient (only one loop) example of "Region Growing" algorithm from a single seed point.

The region is iteratively grown by comparing all unallocated neighbouring pixels to the region, using mathematical morphology. The difference between a pixel's intensity value and the region's mean is used as a measure of similarity. The pixels within the parameter tolerance boundaries around the region's intensities mean are allocated to the region.

This process stops when the regions stops its evolution from an iteration to the next.

Comments and feedback would be very much appreciated, thanks!!!

I would said that this function is limited to small images only, if you change the int8(x) and int8(y) by int16(x) and int16(y), you may be able to work with bigger and difficult images. the black issue seams not solved. can you explain us the functioning or maybe an example so we use your function! Great function!!!!

only applicable for 2D images

very good!
But can you give a specific explanation how to use the function? What does the parametre 'tolerance' mean? how to set its value?

Fix added for the case of black regions.
