Abstract:
A method for encoding low-resolution data having a plurality of pixels and high-resolution data having a higher resolution than said low-resolution data, said high-resolution data having a plurality of pixels, comprising the steps of:encoding said low-resolution data, outputting said encoded low-resolution data, decoding said encoded low-resolution data, and outputting said decoded low-resolution data;determining a pixel of said low-resolution data at a spatially nearest location to each pixel of said high-resolution data from a plurality of pixels of said low-resolution data;predicting said high-resolution data based on said decoded low-resolution data and generating said predicted high-resolution data by outputting said determined pixel of said low-resolution data located at the spatially nearest location to each of said high-resolution data; andencoding said high-resolution data based on said high-resolution data and said predictive high-resolution data and outputting said encoded high-resolution data.
