A MESH-INTERPOLATION SCHEME FOR VERY-LOW BITRATE CODING OF VIDEO SEQUENCES

A very-low bitrate video codec is proposed that processes an image seq uence as a two-component information source. The main difference from state-of-the-art approaches lies in the use of a 3D spatio-temporal in terpolation; it is based on a non-uniform sampling where frames are pr ocessed as 3D blocks, so achieving an adaptive allocation for the info rmation to be transmitted. Residuals are then compressed through a tra nsform coder. Such a method allows for a concurrent and efficient expl oitation of intra-and inter-frame correlations; experimental results s how a good fidelity in decoded sequences, both in terms of subjective and objective quality.
