[M4IF Technotes] Still Texture Coding Wavelet: Tiling Use.

[Francesco Falconi]

Hello to everyone,
and thanks to everyone could help me. I'd like to implement tiling in still texture wavelet coding (ISO 14496 source). The User Guide isn't so clear about the tile use, my aim is to find a way to give a different quantization step (for AC band) for each tile.
In the file parameter (.ctl) I can see these options:
% tiling_disable
% tiling_jump_table_enable
% tile width
% tile height
% target tile 
% QDC-Y,  QDC-UV
% spatial scalability  
%   snr_lev (QY QUV)  
Is it possible modifying these parameters to obtain a different SNRlevel (QY QUV) for each tile? Do you know some link or email which can be useseful for my purpose?
Thank you very much for your time.
