Dear all,
I want to design a my own transform basis matrix.
For 2D case, forward transform is: Y=A*X*B, inverse transform is: Z=C*Y*D...
let's say X, Y, Z, A, B, C, D are 8x8 matrices...
Can anybody tell me what relationship should A, B, C, D have?
1)Orthognality?
2)A=B'?
3)C=D'?
4)A=B^(-1)?
5)C=D^(-1)?
6)B=C?
7)A=D?
...
Thank you very much if you can also poi |
