Is there rgb2lab function for pytorch data (varaible or tensor or torch) read from an image?

same as the title…
is there rgb2lab function in pytorch?

No, but there are some ways to convert your image.

  1. You could add the conversation to your Dataset and just convert the image after loading it:
from skimage import io, color
class MyData(Dataset):
    ...
    def __getitem__(self, index):
        rgb = io.imread(self.images[index])
        lab = color.rgb2lab(rgb)
        x = torch.from_numpy(lab)
        ...
  1. You could try to implement the conversion in PyTorch, if you really need to apply this function on a Tensor.
    Adobe has an older cookbook for the conversion.

I hope it helps!

thank you, good idea!
