So the fully scientific description would be that we add a regularization term that stipulates, that these colors only undergo affine transformations.

所以完全科述就是，我们在公式中添加一个正则项，规定这些颜色只能进行射变换。

This means that there are a ton of different possible solutions for transferring the colors, and we're trying to steer the optimizer towards solutions that adhere to some additional criterion, in our case, the affine transformations.

它意味着转换颜色有许多不同可能解决，我们试图引导优化算法采取那些符合一些额外标准解决，在我们例子中，额外标准就是指射变换。
