Finding a suitable wavelet for image compression applications
S. Masud, John V McCanny · 2002
In this paper we assess the relative merits of various types of wavelet functions for use in a wide range of image compression scenarios. We have delineated different algorithmic criteria that can be used for wavelet evaluation. The assessment undertaken includes both algorithmic aspects (fidelity, perceptual quality) as well as suitability for real-time implementation in hardware. The results obtained indicate that of the wavelets studied the biorthogonal 9&7 taps wavelet is the most suitable from a compression perspective and that the Daubechies 8 taps gives best performance when assessed solely in terms of statistical measures.
