seeded region growing

Hi I want to do seeded region growing. I want clear algorithm on how to grow regions and how to select seeds?

What are different ways of selecting seeds and what are their impact on image?

You should know how to pick the seeds. Otherwise you wouldn't even know that you wanted to use region growing at all. To see what effect it has, experiment around with the magic wand or flood fill tools in Photoshop.

Starting with R2015b, the Image Processing Toolbox has a function grayconnected() that is a magic wand type of function.
