有关将2张图像融合在一起的问题

Question

我正在查看下面链接中的示例代码（示例2：具有Wave风格的Italy Street图片）。

https://github.com/dipanjanS/practical-machine-learning-with-python/blob/master/notebooks/Ch12_Deep_Learning_for_Computer_Vision/Neural%20Style%20Transfer%20Results%20-%20High%20Resolution.ipynb

还要从下面的链接查看输入图像。

https://github.com/dipanjanS/practical-machine-learning-with-python/tree/master/notebooks/Ch12_Deep_Learning_for_Computer_Vision/results/italy%20street

我的问题是这个。为什么要将迭代_1.png至迭代_20.png读入代码？

is_content_image = io.imread('results/italy street/italy_street.jpg')
is_style_image = io.imread('results/italy street/style1.png')
is_iter1 = io.imread('results/italy street/style_transfer_result_italy_street_gatys_at_iteration_1.png')
is_iter5 = io.imread('results/italy street/style_transfer_result_italy_street_gatys_at_iteration_5.png')
is_iter10 = io.imread('results/italy street/style_transfer_result_italy_street_gatys_at_iteration_10.png')
is_iter15 = io.imread('results/italy street/style_transfer_result_italy_street_gatys_at_iteration_15.png')
is_iter20 = io.imread('results/italy street/style_transfer_result_italy_street_gatys_at_iteration_20.png')

似乎您会读懂italy_street.jpg和style1.png，并且代码应完成将图像融合在一起的工作，因此在几次迭代之后，它们被合并为两个图像的污染。这似乎很直观，而不是对多个图像执行“ io.imread”，然后在每次迭代后保存每个图像。我在这里缺少基本的东西吗？或者，那里是否有更好的演示，可以演示如何将两个图像融合在一起？谢谢你的表情。
