Problem with parameter setting .

[Lee-meng-meng]

What does YUV_scales stand for? Why did you set y,u, and v to 1,100,100, respectively?
How do I adjust these three parameters?

Many thanks

YUV is a color space (https://en.wikipedia.org/wiki/YUV). The scaling varies the loss for color versus luminosity (the u,v channels are color).

By setting u and v larger you increase the loss on the color channels. Weighing them more helped avoid weird colors from emerging during training.

Thank you for your reply ~ I found that YUV should be set to 1,300,200 to avoid strange colors when training 1200*800. Is this setting related to the ratio of length to width?
