Structure runlength coding encodes reversibly digital multi-color images. This coding processes the original images efficiently along raster scan lines. Two-dimensional structure of multi-color images is used to enhance its efficiency. The use of the structure makes the coding much more efficient than conventional runlength coding schemes. Even various gradational areas are coded effectively. This paper presents the precise coding method and compares its efficiency with that of a conventional runlength coding scheme.
