<title>Two-dimensional coding of raster image and saving images to WORM in batches</title>

Abstract

In this paper a scheme increasing raster images stored in a WORM is studied. A twodimensional coding method improved from the CCiTT ( Comite Consultatif Interationale Telegraphie et Telephonie) is used to compress the image data. And a means of saving image to the WORM in batches is taken to increase the WORM space utilization ratio.
