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.
