Multi-Scale Wavelet Transformer for Face Forgery Detection. (arXiv:2210.03899v1 [cs.CV])

Currently, many face forgery detection methods aggregate spatial and
frequency features to enhance the generalization ability and gain promising
performance under the cross-dataset scenario. However, these methods only
leverage one level frequency information which limits their expressive ability.
To overcome these limitations, we propose a multi-scale wavelet transformer
framework for face forgery detection. Specifically, to take full advantage of
the multi-scale and multi-frequency wavelet representation, we gradually
aggregate the multi-scale wavelet representation at different stages of the
backbone network. To …
