hi , i read a image and want combine with mask that contain a line on it , i make a mask but i can't combine a image and mask that show line on the reading image
im=imread('apple.jpg');
mask=255*zeros(size(im));
mask=insertShape(mask,'line',[50 50 250 250],'linewidth',10,'color',[255 255 0]);
mask=uint8(mask);
subplot(1,3,1);
imshow(im);
title('original');
subplot(1,3,2);
imshow(mask);

im3 = im;
im3(mask ~= 0) = mask(mask ~= 0);

This burns it into the image. If you just want the line in the overlay above the image without altering the image at all, use plot() or line().

im=double(imread('autumn.tif'));
red = im(:,:,1);
gre = im(:,:,2);
blu = im(:,:,3);
mask=255*zeros(size(red));
mask=insertShape(mask,'line',[50 50 250 250],'linewidth',10,'color',[255 255 0]);
mask_red = mask(:,:,1).*red;
mask_gre = mask(:,:,1).*gre;
mask_blu = mask(:,:,1).*blu;
