Here's a demo:
% Have user freehand draw a mask in the image.
uiwait(msgbox('Draw a region with left button down. Double click inside to finish it'));
h = imfreehand();
vertices = wait(h);
% Create a binary mask
mask = createMask(h);
subplot(2,2,1);
imshow(mask, []);
% Mask the image.
maskedRgbImage = bsxfun(@times, rgbImage, cast(mask,class(rgbImage)));
subplot(2,2,2);
imshow(maskedRgbImage);
