Fractal compression is the lossy compression technique in the field of gray/color image and
video compression. It gives high compression ratio, better image quality with fast decoding …

We present and compare methods for choosing motion vectors for block-based motion-
compensated video coding. The primary focus is on videophone and videoconferencing …

Weighted finite automata (WFA) exploit self-similarities within single pictures and also
sequences of pictures to remove spatial and temporal redundancies. Their implementation …

We make a case that, even with severe efficiency constraints, taking the number of bits to
code each motion vector into account when estimating motion for video compression results …

A rate distortion constrained statistical motion estimation algorithm is presented that leads to
improvements in subband video coding. The main advantages of the algorithm is that it …

There is a tradeoff between the speed of a data compressor and the level of compression it
can achieve. Improving compression generally requires more computation; and improving …

We make a case that taking the number of bits to code each motion vector into account when
estimating motion for video compression results in significantly better performance at low bit …

Many data compression algorithms use ad-hoc techniques to compress data efficiently. Only
in very few cases, can data compressors be proved to achieve optimality on a specific …
