Does this PR ready for merging (after rebasing)? Anything you plan to work on? @wanmeihuali |

The previous experiment does not show any significant improvement with background color...Actually, the PSNR even dropped a bit... I'm not sure if it will get better after rebasing. Anyway, we will only merge it if it does not hurt the metrics. |

I prefer to use "black" background (0, 0, 0) as the default value for training. But at the render time, one can choose to switch between black or white or other custom colors. |

There was a problem hiding this comment.
Could you provide the formula to calculate the gradient properly? I am a bit confused by the name convention.
