发明名称 Image compression using directional predictive coding of the wavelet coefficients
摘要 What is disclosed is a method that includes determining the direction of most probable correlation of a transformed set of image data, and error encoding transformed data, the error determined between a transformed data value and a predicted neighbor data value in the determined direction. In an imaging apparatus that employs a DWT, or Discrete Wavelet Transform to compress an image, the direction of edges in the compressed data in used to generate a more highly correlated error image than typically provided for.
