  • Adaptive coding and decoding
    Patent number: 8611413
    Abstract: A method of transmitting an image portion, in a coding phase, comprises: analyzing a coding context; adapting a parameter of a group of prediction functions that can be used for coding; forming a first predicted descriptor using a selected prediction function; and determining and transmitting a residue (?) between the first predicted descriptor and the current descriptor. The method further includes a decoding phase comprising: analyzing a decoding context; adapting a parameter of a group of prediction functions that can be used for decoding; forming a second predicted descriptor (P*) using a selected prediction function; and combining the second predicted descriptor and the received residue to deliver a decoded version of the current descriptor (V*).
