Deep learning and multi-statistical features: an intra-frame forgery detection video method

In this paper, we propose a technique for detecting spliced video forgeries using statistical clues extracted from the spatial and compression domains inside a suspicious video. The proposed technique employs a multi-feature architecture to train statistical features for every domain using the VGG-16 model. Examining the fused characteristics in specific image regions with great detail exposes instances of manipulation. Both the compression impacts of JPEG and the visual distortions that result from image modification are examined in our research.

In this study, we propose an alternative to the standard methods for detecting spliced forgeries in spatial domain textural analysis, such as entropy-based edges (MER), median filter residual (MFR), gray level regional maxima (FGM), morphological open images (MOI), and morphological erosion images (MEI). Derivative filters of image that may extract statistical information about manipulation traces from compressed data were chosen for artifact detection in double JPEG compression. As an example, the compression domain analysis makes good use of the 2D block Discrete Cosine Transform (DCT). There are three stages that comprise up the suggested method: (1) Video preprocessing splits videos into frames and converts each frame's image to two domain formats: spatial and DCT compression. (2) Take each domain and extract several statistical characteristics. (3) Train VGG16 on a dataset to identify the spatially manipulated area in a video.

The proposed method has been validated and tested on the HTVD and GRIP datasets. The performance measure, such as Splicing forgery accuracy is 93.50% on the GRIP dataset and 92.40% in HTVD.
