I'm making an application that can do a mask/selection of an image like in Photoshop. I need an algorithm that works like the "Magic Wand" in Photoshop. In general any information on masking/selection would be much appreciated. Thanks.

How advanced does it need to be?
Something simple like a flood fill until the contrast (compared to the center or previous pixel) exceeds a threshold value might be sufficient.

[google] for "freeman chain" and "image recognition". This might help you out.
