These different methods are then examined as to their relative merits and disadvantages. A study of pel amplitude frequency distributions and pel difference amplitude distributions is then made, using standard digitized images. From these results, companded DPCM followed by negacyclic coding is chosen as the source coding scheme to be investigated. A companded DPCM image processing and transmission system is then simulated. The resulting pictures are presented, along with a proposal for a system incorporating a negacyclic codec"--Abstract.
