  • Abstract
    We describe N2C-EX1, a parallel, pipelined version of a modified LOCO-I lossless compression algorithm used within the JPEG-LS coding scheme. This version takes into account the sequential nature of the original LOCO-I algorithm due to the use of context statistics in coding the residual errors of the predictive phase and uses three pipelines to carry out concurrently the encoding on independent pixels extracted from the serial stream of incoming data.
