How to improve the way 'zoomIm' is used?
[H, W, ~] = size(im);
zoomIm = zeros([H W 3], 'uint8');
parfor j=1:3
for i = 1:284000
if k(i)==1
zoomIm(startY(i):stopY(i), startX(i):stopX(i), j) = im(I(i), J(i), j);
end
end
end
I want parfor to parallelize RGB layers.
BTW- input variable's data is given in attached file :)
I want to parallelize RGB layer because each layer is taking same amount of time..
Any more efficient way apart of 'PARFOR' is also welcomed, which is supported for code generation.
Thanks for consideration :D
