The work on image processing of American Sign Language was supported by National Science Foundation, Science and Technology to Aid the Handicapped, Grant PFR-80171189. Special thanks to George Sperling, who conceived the American Sign Language project and provided the support and encouragement that made this image processing research a reality. We also wish to acknowledge the assistance of Thomas Riedl, August van der Beek, and Robert Picardi, and the helpful comments of Robert Hummel.

N2 - A method for the efficient coding of line drawings is discussed. The intent is to provide an extremely low bandwidth representation for images, preserving "intelligible" image content but not necessarily image quality. This has led to an image transformation involving edge enhancement, detection, line thinning, and polygonal splining which is termed the polygonal transformation. The graph-like image which results from this transformatiom is coded quite efficiently by using vectorgraph coding, which codes a series of vectors in a manner similar to that used in many computer graphics systems. This technique has been applied to a body of images of American Sign Language and the results are encouraging.
