Paper Abstract

A very low bit rate image sequence coding scheme is introduced. It is based on directional decomposition, which was used previously in static image coding. An image sequence is decomposed into a low-frequency sequence and a set of directional high-frequency sequences. Very high compression is obtained by detecting and coding the movements of directional edges extracted from directional high-frequency sequences. At this stage of research, data rates from 50 to 60 kbit/s can be achieved, though by refining the method even larger compression is expected.
