Which algorithms similar to Watershed are efficient for region based segmentation. For my application watershed didn't detect the regions correctly. i created the markers using morphological operations.

Thanks @Balaji Renganathan but, The distance transform Calculates the distance to the closest zero pixel. the input to distance transform is itself a binary image.

I need to segment various regions of the image Some what similar to this: http://www.mathworks.in/help/images/examples/marker-controlled-watershed-segmentation.html

"For my application watershed didn't detect the regions correctly." Can you explain why? Have you tried to replicate this with opencv? Can you share your code?

You should try Gradient (Region Growing) and Active Contours.
