Abstract

The invention relates to the technical field of computer vision, in particular to a face forgery detection method based on an image domain and frequency domain double-flow network. The detection method comprises a model training stage and a model inference stage. In the model training stage, a server with high computing performance is used for training a network model, network parameters are optimized by reducing a network loss function until the network converges, and a double-flow network model based on an image domain and a frequency domain is obtained; in the model inference stage, the network model obtained in the model training stage is utilized to judge whether the new image is a face counterfeit image or not. Compared with a method for converting face counterfeit detection into a dichotomy problem, the method realizes hierarchical classification, and can achieve better detection precision by using diversified supervision information of counterfeit images.

Description

Technical field [0001] The invention relates to the field of computer vision technology, and specifically relates to a face forgery detection method based on an image domain frequency domain dual-stream network. Background technology [0002] With the development of advanced face synthesis algorithms, various realistic fake faces have also been produced, and their application on social media has attracted great attention. The malicious use of fake faces will bring huge adverse effects to individuals and society, so it is very important to detect fake faces. [0003] There are many challenges in the face forgery detection task, especially the diversity of forgery algorithms and the fact that face forgery images circulated on the Internet are often of low quality and difficult to detect. [0004] Early research attempted to use handcrafted features or simply modify existing neural networks. MesoNet designed a shallow neural network consisting of two initial modules and two c...
