98. Walsh-Hadamard Transform
Y = HXHT
H =
1 1 1 1
1 1 -1 -1
1 -1 1 -1
1 -1 -1 1
[ ]HT is the transpose of H.
Take advantage of
the correlation to
reduce redundancy.
99. Adaptive Quantization
128 quantization level.
Different quantization level in single frame.
1st order luma DC
1st order luma AC
2st order luma DC
2st order luma AC
2st order chroma DC
2st order chroma AC
101. Supports distribution updates on a per-frame
basis
Boolean arithmetic coder
Stable probability distributions within one
frame
Keyframes reset the probability values to the
defaults
