  • Patent number: 12147550
    Abstract: A steganography method and an apparatus embedding a hidden message in a video stream of an original cover video to produce a stego video using a generative neural network. The original cover video is a video stream as opposed using an image. A discriminant neural network is used to correct a generated video compared to an original cover video. The generated neural network is trained when the generated video is determined to be real by the discriminant neural network. A second stego video is acquired by adversarial training through a mutually adversarial relationship between a generative neural network and an discriminant neural network. The embedding technique is one of pre-embedding, intra-embedding, or post-embedding.

  • Patent number: 12143698
    Abstract: A method creating a high-speed hyperspectral video by acquiring images from a hyperspectral high speed camera and forming a of a three-dimensional data cube by including spectra for each pixel in addition to a two-dimensional spatial information of an image taken with a general camera. Dividing successive three-dimensional data cubes obtained by photographing images with a spectral scanning type hyperspectral camera. Acquiring the three-dimensional data cubes for each specific time point and creating three-dimensional data cubes for as many as the number of spectra. Then separating a region corresponding to a moving object and a region corresponding to a background from the created data cubes. Acquiring spectral values according to spatial locations of the images and reconstructing a three-dimensional data cube with all spectral values for each specific time point with regard to the region with motion through a generative adversarial network algorithm.
