I have an issue while using getimage() command. I am trying to use a figure, first with imshow to initialize a color image (rgb from code) of size 1944x2592x3 pixels. After this, I want to overlay the bounding-boxes on the color image. I tried using getimage() to obtain the full-size image (1944x2592x3 pixels). It worked, but I am not getting the bounding-boxes overlaid image of full-size. Instead, I am getting a color image (rgb) of full-size.
If I use getframe(), I am getting the overlaid image but of smaller size. Anybody, please help me. I need the image(s) of the original size.
f = figure('Visible', 'off');
a = axes('Visible','off');
for k = 1 : length(st)
thisBB = st(k).BoundingBox;
rectangle('Position', [thisBB(1),thisBB(2),thisBB(3),thisBB(4)], EdgeColor','G','LineWidth',2 );
frame = getimage(f);
saving frame.cdata into a variable.
