Motion-Adaptive TV Data Compression

Based on digitized TV frames a computer simulation study was conducted on a motion-adaptive TV data compression scheme, defined as one in which a 2-dimensional transform applied to subblocks is followed by the transmission to the receiving site of only changed subblocks. Performance was measured both by calculation of Normalized Mean Square Error and by subjective viewing of reconstructed frames. Two systems designs leading to 512x512 resolution operation (one based on the Hadamard and one on the Discrete Cosine Transform) were prepared.
