So, our edge kernels looked for image patches with strong differences from right to left or up and down.

因此，我们的边缘内核寻找从右到左或上下具有强烈差异的图像块。

This extension is also capable of texture synthesis, which means that we give it a small image patch that shows some sort of repetition, and it tries to continue it indefinitely in a way that seems completely seamless.

这项扩展还可以被用在纹理合成方面，这意味着我们可以输入一小块图像，用来表示某种可重复的纹理，之后这种算法会尝试把这一小块纹理无限扩展，并且看起来完全无缝。
