On-line Colour Image Compression Based on Pipelined Architecture

Abstract

This paper reports a pipelined architecture that can support on-line compression/decompression of image data. Spatial and spectral redundancy of an image data file is detected and removed with a simple and elegant scheme that can be easily implemented on a pipelined hardware. The scheme provides the user with the ability of trading off the image quality with the compression ratio. The basic theory of byte error correcting code (ECC) is employed in this work to compress a pixel row with reference to its adjacent row. A simple scheme is developed to encode pixel rows of a color image.
