(十一)视频批量转卡通风格、视频批量转动漫风格、大量视频批量处理

本文的代码的功能是：可以对视频批量处理变换成动漫、卡通的风格，共有5种风格可以选择，使用了人工智能的算法。

如果提示过期，可以向博主索要新的SN文件。

一、主要功能：
以下的Python代码的功能：批量选择视频、完美使用界面，主要包括：
1、对视频进行风格变换，转换成动漫、卡通等风格，并输出变换后的文件；
2、可以批量处理，在选择文件的对话框里可以选择多个文件，进行批量操作；
3、如果电脑有GPU，则会自动选择GPU处理，加快处理速度；
4、风格一共有5种，分别是：通用日漫风格、3D立体风格、素描黑白风格、手绘彩色风格、>艺术范风格
5、信息统计里面可以实时显示处理的各种统计信息；
6、视频处理完毕后自动进行音频的处理与合成。

软件运行界面如下：
