which wavelet transform for image compreesion yields better compression and better PSNR value?

i am studying about the wavelet transform . i would like to know that which wavelet TRANSFORM yields GOOD PSNR and BETTER COMPRESSION RATIO. thank you all

[vishnu]

please any one guide me

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

I ASKED WHETHER CURVELET OR BANDLET OR LIKE SO AND SO ..

[Wayne King]

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

Try complex Morlet Wavelet
