False video detection method and false video detection device using the same

Abstract

A false video detection method is provided. The method includes: retrieving N video segments in a target video, wherein each video segment includes M image frames; performing a feature retrieving procedure on the N×M image frames to obtain feature maps corresponding to the N×M image frames; inputting the feature maps into a time-attention model to obtain concentrated feature; multiplying the concentrated feature with the feature maps to obtain first enhanced feature maps, adding the first enhanced feature maps with the feature maps to obtain second enhanced feature maps, and inputting the second enhanced feature maps into a fully connected layer to obtain a determination result outputted by the fully connected layer, wherein the determination result indicates that the target video is true or false.
