I want to train 3-channel greyscale image.

[C-Jaewon]

my datasets : The pixels of text are close to 0, and the pixels of background are close to 1.
my datasets is 3-channel grayscale imges. I want to train 3-channel grayscale images, not binay images.
I want the learning result to have a value of (0, 1). -> 0 ~ 1
