Low quality deepfake detection device and method of detecting low quality deepfake using the same

Abstract

A deepfake detection device may include a data input unit that receives an input image including a low-quality deepfake video, a branch-based super-resolution training unit that enhances the resolution of the input image through unsupervised super-resolution training and generates a plurality of super-resolution images having different sizes, and a multi-scale training unit that performs multi-scale training, without resolution conversion, on the plurality of super-resolution images having different sizes, respectively. The multi-scale training unit may synthesize multi-scale training results for the plurality of super-resolution images having different sizes, respectively, and determine whether the input image is a deepfake based on the multi-scale training results.
