What is the range of the score? I got 128 for my picture

[d5423197]

Hello there,

I would like to ask if there are any requirements on the size of the picture, the shape of the picture, and the color channel of the pic?

I converted one of my pics into gray and I got 128 for the score.

Then I used the original 3 channel pic, I got 24 for the score.

The color channel should be RGB. The score goes from 0-100.
