I use roipoly command to draw sides of tumor suspicious area. And after drawing I want to extract that region from original image.
Using which matlab command I can extract this area from original image?
and my second question if it is possible how will I increase whiteness of tumor suspicious area in that region?
I can increase sharpness with fspecial and roifilt2 command in that region but I need to increase whiteness.
(The image is taken from mias database)

"I draw a polygon which include tumor suspicious region. I need that polygon's extraction from original image .
Is there any matlab command to extract that region which I draw?"

I think what you are asking for is how to apply a mask to an image.
