  • Multi dimensional image compression and decompression method using feature points on a luminance contour line
    Patent number: 5647024
    Abstract: A method of compressing and decompressing a multi-dimensional image. Video data including luminance data distributed at least in two-dimensions is compressed for subsequent coding. The resulting codes are decompressed to reproduce the video data. A specific number of representative pixels are extracted from a plurality of pixels consisting of the digital signal of the video data. Texture data is also extracted from the digital signal of the video data. The representative pixels and the texture data are coded. The coded representative pixels and the texture data are then decoded. The video data is reproduced using the decoded representative pixels and the texture data.
