System and method for encoding and decoding enhancement layer data using descriptive model parameters

摘要

There is provided an image encoding system (300, 400) including an encoder (300) for receiving input image data and generating corresponding encoded image output data. The encoder includes image processing features (310, 320, 330, 360) for processing said input image data to generate for each input image therein a plurality of corresponding image layers including at least one basic layer BLOP and at least one enhancement layer ELOP. Moreover, the encoder (300) further includes encoding features (350) for receiving said image layers and generating therefrom the encoded image output data. The encoding features further comprising block selecting features (340) for selecting one or more sub-regions of said at least one enhancement layer and modelling said one or more sub-regions for representation thereof in the image output data by way of descriptive model parameters.
