Interframe Vs. Intraframe Compression Of Image Sequences
Paul Roos, Max A. Viergever · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
In this paper several reversible (error-free) decorrelation schemes for time series of images are described. Distinction is made between spatial-temporal schemes versus temporal-spatial schemes, motion compensating versus non compensating schemes, and between temporal extrapolation versus temporal interpolation methods. Simulation on three series of angiograms shows that reversible interframe decorrelation offers no significant improvement over intraframe decorrelation by means of Hierarchical Interpolation. For a sequence of video-conferencing images interframe decorrelation did yield improved performance over intraframe HINT. However, this type of images is usually compressed irreversibly.
