实现也非常简单。
首先,整理一下思路:
「Real Time Image Animation」使用一阶运动模型,根据已有视频,让静态图动起来。
左图为原始图片,中间为生成结果,右侧为原始视频。
但是,这个项目只能处理图像,不能保留音频。
所以,我们需要先将音频保存,再将处理好的视频和音频进行合成。
这个功能,就用我们下载好的 ffmpeg 实现。
编写如下代码:
import subprocess
import os
from PIL import Image
def video2mp3(file_name):
"""
将视频转为音频
:param file_name: 传入视频文件的路径
:return:
"""
outfile_name = file_name.split('.')[0] + '.mp3'
cmd = 'ffmpeg -i ' + file_name + ' -f mp3 ' + outfile_name
subprocess.call(cmd, shell=True)
def video_add_mp3(file_name, mp3_file):
"""
视频添加音频
:param file_name: 传入视频文件的路径
:param mp3_file: 传入音频文件的路径
:return:
"""
outfile_name = file_name.split('.')[0] + '-f.mp4'
subprocess.call('ffmpeg -i ' + file_name
+ ' -i ' + mp3_file + ' -strict -2 -f mp4 '
+ outfile_name, shell=True)
搞定,视频转音频,以及音频合成都搞定了。
我们需要对「Real Time Image Animation」这个项目进行修改,修改 image_animation.py 文件。

然后下载算法需要的权重文件和视频图片素材。
修改好的代码、权重文件、视频图片素材,我都已经打包好了,拿来直接用也可以。

运行命令:
python image_animation.py -i path_to_input_file -c path_to_checkpoint -v path_to_video_file
path_to_input_file 是输入的模板图片。
path_to_checkpoint 是权重文件路径。
path_to_video_file 是输入的视频文件。
如果使用我打包好的程序,可以使用如下指令直接运行,获得文章开头的视频:
python image_animation.py -i Inputs/trump2.png -c checkpoints/vox-cpk.pth.tar -v 1.mp4
最后生成的视频存放在 output 文件夹下。
大功告成!

算法处理视频的速度很快,用 GPU 几秒钟就能搞定。
我还生成了 PDD 演唱《Unravel》版,最后再回味一下。
兄弟,我裂开了呀!
