AnimeGANv2, the improved version of AnimeGAN.
A Tensorflow implementation of AnimeGAN for fast photo animation ! 日本語
The paper can be accessed here or on the website.
Update:
data_mean.pyis used to calculate the three-channel(BGR) color difference of the entire style data, and these difference values are used to balance the effect of the tone of the style data on the generated image during the training process. For example, the overall tone of the Hayao style data is yellowish.adjust_brightness.pyis used to adjust the brightness of the generated image, which is based on the brightness of the input photo.- Some training hyperparameter changes.
Online access: Be grateful to @TonyLianLong for developing an online access project, you can implement photo animation through a browser without installing anything, click here to have a try.
Good news: tensorflow-1.15.0 is compatible with the code of this repository. In this version, you can run this code without any modification. The premise is that the CUDA and cudnn corresponding to the tf version are correctly installed. Maybe the versions between tf-1.8.0 and tf-1.15.0 are also supported and compatible with this repository, but I didn’t make too many extra attempts.
Some suggestions:
- since the real photos in the training set are all landscape photos, if you want to stylize the photos with people as the main body, you may as well add at least 3000 photos of people in the training set and retrain to obtain a new model.
- In order to obtain a better face animation effect, when using 2 images as data pairs for training, it is suggested that the faces in the photos and the faces in the anime style data should be consistent in terms of gender as much as possible.
- The generated stylized images will be affected by the overall brightness and tone of the style data, so try not to select the anime images of night as the style data, and it is necessary to make an exposure compensation for the overall style data to promote the consistency of brightness and darkness of the entire style data.
News:
AnimeGANv2 has been released and can be accessed here.
The improvement directions of AnimeGANv2 mainly include the following 4 points: 1. Solve the problem of high-frequency artifacts in the generated image.
2. It is easy to train and directly achieve the effects in the paper.
3. Further reduce the number of parameters of the generator network.
4. Use new high-quality style data, which come from BD movies as much as possible.
