In the Setup:
BCD
AE
And A, B, C, D are known, and we want to guess at E what would be the best general purpose predictive coder?
So far, ones that have given good results are:
E = 0.75A - 0.5B + 0.75C,
E = 0.4A + 0.4C + 0.1(B + D),
E = {
min(A, C) if B >= max(A, C) //This is the proposed JPEG-2 Adaptive Predictor
max(A, C) if B <= min(A, C)
A + C - B otherwise
}
E = {
min(A, C) if B >= max(A, C)
max(A, C) if B <= min(A, C)
[Replace with one of the first two predictors]
}
What are some better ones, and which would everyone here say gives the best results?
