Subband coding using local bases in multiple dimensions |
摘要 |
A method and apparatus for encoding and decoding multi-dimensional signals is disclosed. Non-separable multi-dimensional filters are utilized. Analysis filters encode the signal by applying a windowing function and a reduction function to the multi-dimensional signal. This produces a prototype. The prototype is then replicated as many times as required by utilizing a modulation function. Synthesis filters then decode the encoded signal by utilizing the inverse of the encoding process.
