ABSTRACT:
Device for transmitting and/or storing signals presented thereto representing the textures of different areas of a video picture. The device includes a sampling stage for deriving a reference sample of the texture signals from a given picture area, and a coding stage for coding the reference sample signal as well as area signals representative of texture over the entire area from which the sample has been taken. The coded output signals of the coding stage may be transmitted by a transmission medium such as a communication channel and/or a store. A decoding stage then decodes the coded signals, and a texture synthesis stage uses the decoded sample signals to enhance the decoded area signals, thereby effectively achieving synthesis of a reproduction of the relevant picture area having a texture closely resembling the texture of such area of the original picture.
