Vishnu, I'm not sure what you mean by "which" wavelet transform. The critically-sampled wavelet transform or wavelet packet transform will yield the best results of the wavelet transforms if compression is the primary concern.
See the following functions in the Wavelet Toolbox, wdencmp, wpdencmp, and measerr

Hi Vishnu, that is impossible to answer in general because it depends on the object you are trying to represent.

Try complex Morlet Wavelet
