In the paper you mention that you tested images from the imagenet with the new WB settings, do these images need to be normalised before being fed into the vgg or resnet models?

Hi Mr Mahmoud,
Can we increase the number 10 in demo_batch.m, up to number of images in my directory?
It is about these codes..
if NumOfImgs > 10
error('Cannot generate more than 10 images for each input image');
end

Could you explain what the letters "C/D/F/T/S" means in, like '_F_AS' and '_T_CS'?
Much appreciate it.

Please I got the issue in matlab:
Index exceeds the number of array elements (0).

Error in WBAug (line 164)
indices(i)}),...

Error in demo_WB_color_augmentation (line 75)
success = WBAug(training_set_dir, training_ext, output_dir, output_ext, ...

I believe that it is because my grougthruth images are logical type, how to fix this?

Hi Thanks for amazing works!

for Python Api: Can we set the output to be C/D/F/S/T rather than generate by num its self?

If you faced the following error in Matlab:

Please replace the lines 55 and 56 in synthWBmodel class and the lines 55 and 56 in synthWBmodel_GPU class with the following lines:
diff_u=abs(repmat(Iu,[1,size(A,2)])-repmat(A,[size(Iu,1),1]));
diff_v=abs(repmat(Iv,[1,size(A,2)])-repmat(A,[size(Iv,1),1]));

The old Matlab versions don't offer this broadcasting operation. In the new versions of Matlab, this repmat operation is automatically applied when the first/second operand is a single row vector and the second/first operand is a single column.
