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?
