Hello! I am a little rusty on my matlab and would love any and all feedback. I am creating a new image using smaller images (think collage style). I am happy with the output image. However, I would like to add gaussian noise to the output image. I am having issues because the imnoise function does not work with an image object datatype. I'm sure there is an easy solution but I can't seem to find exactly what I am looking for. Thanks in advance.
image(B_1);
hold on
image(pos, pos2 , Hit_1);
image(pos5, pos6, Hit_2);
image(pos3, pos4, Noise1);
rectangle('Position', [pos pos2 s s], 'EdgeColor','r')
rectangle('Position', [pos3 pos4 s2 s2], 'EdgeColor','r')
