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

所以完全科学的描述就是，我们在公式中添加一个正则项，规定这只能进行射变换。

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.

它意味着转换有许多不同可能的解决方案，而我们试图引导优化算法采取那符合一额外标准的解决方案，在我们的例子中，额外标准就是指射变换。
