BW2=roipoly;
BW2=uint8(BW2);
BW=(BW1+BW2);
[r c]=size(BW);
for i=1:r
for j=1:c

It's more efficient in MATLAB to type in BW=BW*254+1 instead of two cycles because it is optimized for matrix computation.

Hello there. I want to get an object in the rgb picture, how can I do that. For example, there is a banana on the table and the background is black. How can I get only the banana picture from the picture.
