Using Noise Level to Detect Frame Repetition Forgery in Video Frame Rate Up-Conversion

open access: yesFuture Internet, 2018
Frame repetition (FR) is a common temporal-domain tampering operator, which is often used to increase the frame rate of video sequences. Existing methods detect FR forgery by analyzing residual variation or similarity between video frames; however, these
