Embodiment Construction
[0037] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below through specific embodiments and accompanying drawings.
[0038] In one embodiment of the present invention, a high embedding capacity video steganography method based on temporal residual convolution modeling is provided, comprising the following steps:
[0039] 1. To be embedded video preprocessing. First, the first frame of the input secret video is marked as a reference frame, and then the amount of change between each subsequent frame and the reference frame is calculated. If it is less than the set threshold, it is marked as a residual frame, otherwise it is marked as a new reference frame. Repeat the above steps until all frames in the video are marked.
[0040] 2. Hide secret information. First select a steganographic video and divide it into video frames (cover). Then match it with the video...
