Is there a way to use 2 vectors of pixel coordinates to quickly dump the pixel values into a 3rd vector?
Currently, I am using the following for loop, but it is very slow:
for j=1:length(x)
pixel_vals(j) = img(x(j),y(j));
end
where, 'x' and 'y' are the x,y coordinates (1xN vector form).
Many thanks!
