How to visualize ab channel of images like that in your paper

Hi @babyein ,

The snippet looks like the following (using matlab):

im = imread('sample.png');
figure; imshow(im);
lab = rgb2lab(im);
l = uint8(lab(:, :, 1)*2);
size_im = size(im);
ab = zeros(size_im(1), size_im(2), 3);
ab(:, :, 1) = 70;
ab(:, :, 2:3) = lab(:, :, 2:3);
ab = lab2rgb(ab);
%ab = uint8(ab);
figure; imshow(l);
figure; imshow(ab);
%imwrite(l, 'sample_l.png');
%imwrite(ab, 'sample_ab.png');

I am closing this issue now, but feel free to reopen if the code does not work.
