Re: PAQ compression

Thanks...
Is there a way to define a model to PAQ such that it uses pixels from a
different file (since I know these images have exactly the same RGB
values... althought I dont know where in the file they are...)

For example, what will be the performance of PAQ if two exact images
are concatenated? will the total compression be better than if they
were PAQd seperately? If so, how is this working with your adjacent
pixel model technique?

Today, BWT on these images would have transformed those same values to
appear next to each other in the column L and so with BWT that performs
well...

Thanks
Lyle
