Abstract :
JPEG2000 Part 2 allows the application of arbitrary wavelet decomposition structures (wavelet packet bases). Efficient anisotropic wavelet packet basis selection for the coding framework of JPEG2000 has been developed and evaluated. Previous work focused on isotropic wavelet packet basis selection algorithms for JPEG2000, which serves as basis for the performance of the assessment of anisotropic wavelet basis selection. Several cost functions are applied in a top-down anisotropic wavelet packet selection scheme. Our evaluations employ state-of-the-art quality assessment tools supplementary to PSNR evaluations.
