  • Adaptive prediction for binary encoded documents containing a mixture of text, line drawings and halftones
    Patent number: 4559563
    Abstract: This is a circuit and method for adaptively selecting one of a plurality of predictor patterns to encode a stream of image data blocks such as would be output from a raster-input-scanner. A variety of halftone and nonhalftone predictor patterns are used and compared, with the best one being selected to predict the next block. Using this technique, the best predictor pattern is usually selected, predicted data buffering is not needed, and no code need be transmitted with the data to the receiver to specify the predictor to be used in the deprediction process since the same basic information is also available to the receiver.
