Abstract
A method of encoding data in an encoder to generate corresponding encoded data includes receiving the data to be encoded and analyzing sub-portions of the data to be encoded to determine one or more encoding algorithms which are to be applied to encode the sub-portions, wherein the one or more encoding algorithms include at least one interpolation algorithm; computing one or more interpolation parameters for the at least one interpolation algorithm which are representative of data values of the sub-portion of the data to be encoded by the at least one interpolation algorithm; encoding a remainder of the sub-portions of the data to be encoded using the one or more encoding algorithms; and combining data generated in the computing and encoding to generate the encoded data. A method is also disclosed for decoding encoded data in a decoder. The methods may be employed in an encoder, decoder, and codec.
