推荐答案
这是一种方法-
N = 200; %// this decides the size of image
[X,Y] = meshgrid(-1:1/N:1, -1:1/N:1) ;
nrm = sqrt(X.^2 + Y.^2);
out = uint8(255*(nrm/min(nrm(:,1)))); %// output image
figure, imshow(out) %// show image
输出-
如果您希望用白色边框填充输出(如预期输出图像所示)，则可以使用 padarray -
If you would like to pad the output with white boundary as shown in the expect output image, you can do so with padarray -
padsize = 50; %// decides the boundary width
out = padarray(out,[padsize padsize],255);
