Embodiment Construction
[0107] The following is a further description of the technical solution of the high-capacity H·265 video information hiding method with high efficiency and fidelity provided by the present invention in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention and implement it.
[0108] The present invention proposes a built-in embedded extraction method suitable for high-capacity hiding of H.265 video information, eliminates distortion and drift within video frames, improves video quality, and combines DST / DCT coupling factor pair with video image texture features (i.e., intra-frame prediction) direction) for information steganography. The experimental results show that: this method is practical and efficient. While having a high embedding capacity, the peak signal-to-noise ratio before and after embedding changes very little, and there is no subjective visual difference after embedding information in the video.
