Abstract
Two important classes of coding schemes that use the spatial correlation of picture elements in reducing data redundancy are the differential pulse-code modulation (DPCM) and the unitary transform coding techniques. We will study the performance of an 
th order DPCM system for ranging from 1 to 22 and compare it to the performance of the unitary-transform techniques (Hadamard, Fourier, and KarhunenLoève) in coding two monochrome still pictures. We will also consider the sensitivities of the coding systems to picture-to-picture variations.
