As long I understand the scalogram representation of
wavelet coefficients, I think you shouldn't interpolate
between intermediate values.
Sloppy spoken:
The scalogram shows the
strength of each wavelet coefficient sorted by the
corresponding resolution scale, i.e. sorted from a coarse
to fine (or vice versa) representation of your data.
So, why do you want to interpolate between some values?
