Paper Abstract

This paper describes research which extends transform and linear predictive spatial domain image coding concepts to the coding of frame-to-frame sequences of digital images. The emphasis is directed towards interframe image coding systems that exploit temporal as well as spatial image redundancies. Interframe coder implementations investigated include three-dimensional unitary transform coders and hybrid coders which employ two-dimensional transforms in the spatial domain coupled with first-order DPCM predictive coding in the temporal domain. Based on a statistical image representation, models are developed for transform coefficient and transform coefficient temporal difference variance matrices. Using these models, theoretical MSE performance levels for both coders are determined as a function of spatial subblock size. Results are verified by computer simulation experiments.
