Simple face swapping for already face-aligned images

python test_one_image.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path crop_224/6.jpg --pic_b_path crop_224/ds.jpg --output_path output/

Face swapping for video

  • Swap only one face within the video(the one with highest confidence by face detection).
python test_video_swapsingle.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --video_path ./demo_file/multi_people_1080p.mp4 --output_path ./output/multi_test_swapsingle.mp4 --temp_path ./temp_results
  • Swap all faces within the video.
python test_video_swapmulti.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --video_path ./demo_file/multi_people_1080p.mp4 --output_path ./output/multi_test_swapmulti.mp4 --temp_path ./temp_results
  • Swap the specific face within the video.
python test_video_swapspecific.py --pic_specific_path ./demo_file/specific1.png --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --video_path ./demo_file/multi_people_1080p.mp4 --output_path ./output/multi_test_specific.mp4 --temp_path ./temp_results

When changing the specified face, you need to give a picture of the person whose face is to be changed. Then assign the picture path to the argument "--pic_specific_path". This picture should be a front face and show the entire head and neck, which can help accurately change the face (if you still don’t know how to choose the picture, you can refer to the specific*.png of ./demo_file/). It would be better if this picture was taken from the video to be changed.

  • Swap multi specific face with multi specific id within the video.
python test_video_swap_multispecific.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --video_path ./demo_file/multi_people_1080p.mp4 --output_path ./output/multi_test_multispecific.mp4 --temp_path ./temp_results --multisepcific_dir ./demo_file/multispecific

The folder you assign to "--multisepcific_dir" should be looked like:

$Your folder name$

├── DST_01.jpg(png)
└── DST_02.jpg(png)
└──...
└── SRC_01.jpg(png)
└── SRC_02.jpg(png)
└──...

The result is that the face corresponding to SRC_01.jpg (png) in the video will be replaced by the face corresponding to DST_01.jpg (png). Then the character corresponding to SRC_02.jpg(png) will be replaced by the face of DST_02.jpg(png), and so on. Note that when using your own data and naming it, do not remove the 0 in SRC_(DST_)01.jpg(png), etc.

Face swapping for Arbitrary images

  • Swap only one face within one image(the one with highest confidence by face detection). The result would be saved to ./output/result_whole_swapsingle.jpg
python test_wholeimage_swapsingle.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --pic_b_path ./demo_file/multi_people.jpg --output_path ./output/
  • Swap all faces within one image. The result would be saved to ./output/result_whole_swapmulti.jpg
python test_wholeimage_swapmulti.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --pic_b_path ./demo_file/multi_people.jpg --output_path ./output/
  • Swap specific face within one image. The result would be saved to ./output/result_whole_swapspecific.jpg
python test_wholeimage_swapspecific.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --pic_b_path ./demo_file/multi_people.jpg --output_path ./output/ --pic_specific_path ./demo_file/specific2.png
  • Swap multi specific face with multi specific id within one image. The result would be saved to ./output/result_whole_swap_multispecific.jpg
python test_wholeimage_swap_multispecific.py --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_b_path ./demo_file/multi_people.jpg --output_path ./output/ --multisepcific_dir ./demo_file/multispecific

About watermark of simswap logo

The above example command line is to add the simswap logo as the watermark by default. After our discussion, we have added a hyper parameter to control whether to remove watermark.

The usage of removing the watermark is to add an argument: "--no_simswaplogo" to the command line, take the command line of "Swap all faces within one image" as an example, the following command line can get the result without watermark:

python test_wholeimage_swapmulti.py --no_simswaplogo --isTrain false  --name people --Arc_path arcface_model/arcface_checkpoint.tar --pic_a_path ./demo_file/Iron_man.jpg --pic_b_path ./demo_file/multi_people.jpg --output_path ./output/

Difference between single face swapping and all face swapping are shown below.

Parameters

Parameters Function
--name The SimSwap training logs name
--pic_a_path Path of image with the target face
--pic_b_path Path of image with the source face to swap
--pic_specific_path Path of image with the specific face to be swapped
--multisepcific_dir Path of image folder for multi specific face swapping
--video_path Path of video with the source face to swap
--temp_path Path to store intermediate files
--output_path Path of directory to store the face swapping result
--no_simswaplogo The hyper parameter to control whether to remove watermark

Note

We expect users to have GPU with at least 6G memory. For those who do not, we will provide Colab Notebook implementation in the future.
