Using repmat instead of subplot - adding grid lines and points
显示 更早的评论
Hi, Im trying to remove the gaps between subplots and have read the following way to do it using repmat that works well.
A=[IM1 IM2 IM3;IM4 IM5 IM6];
A_new = repmat(A, [1 1]);
imshow(A,[low,high]);
1: Is it possible to highlight the separate images by adding say red lines on the composite image to be able to visually see the separation of the images i.e.
2: For each image IM1, IM2 etc. I have the x and y coordinates of points that I want to add to the graphic.
How do I add the x, y positions that correspond to IM1 to the correct location and so on?
thanks Jason

If you know the size of your images then can't you just use a standard plot command
e.g.
A = [rand(100) rand(100) rand(100); rand(100) rand(100) rand(100)];
figure; imshow( A )
hold on
plot( [100 100], [1 200], 'r' )
etc
