Of course we are ignoring one last thing to get a finished grayscale image, and that is local value.

当然，为了获得最终的灰度图像，我们忽略了最后一件事，那就是局部值。

So as some of these strokes might actually wind up being part of the finished image, I will be implementing stroke direction a bit more in the hair.

因此， 由于其中一些笔触实际上可能会成为最终图像的一部分，因此我将在头发中更多地实现笔触方向。
