On-line Image Compression based on Pipelined Architecture

Successes of multimedia applications demand on-line transmission of image data. This in turn demands on-line compression/decompression of image data files. This paper reports a pipelined architecture that can support on-line applications of image data. Spatial redundancy of an image data file are 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 facility 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 monochrome image.
