Assign value to a circular mask
7 views (last 30 days)
I used the following code to generate a circle mask located at [cX, cY] on a 500 by 500 "film":
cX=200; cY=100; r=30; % radius of the circle width=500; height=500;
[W,H]=meshgrid(1:width, 1:height); mask=sqrt((W-cX).^2+(H-cY).^2)<=r; imshow(mask) colorbar
But for now the circle value = 1, and the rest of the film value = 0; How can I assign specific value (for instance, 5) to the circle value?
Thank you! Sonia
