Texture classification by wavelet packet signatures
 IEEE Transaction PAMI
, 1993
"... This paper introduces a new approach tocharacterize textures at multiple scales. The performance of wavelet packet spaces are measured in terms of sensitivity and selectivity for the classi cation of twenty ve natural textures. Both energy and entropy metrics were computed for each wavelet packet a ..."

Brushlets: steerable wavelet packets
 In Beyond wavelets
, 2003
"... Abstract. We address the problem of describing an image with a library of steerable wavelet packets. Inspired by the duality between local trigonometric bases and wavelet packets, we construct wavelet packets of two variables in the Fourier domain using local Fourier bases.

Mean Size of Wavelet Packets
"... We study the mean size of wavelet packets in Lp. An exact formula for the mean size is given in terms of the pnorm joint spectral radius. This will be a corollary of an asymptotic formula for the Lpnorms on the subdivision trees. Then the stability and Schauder basis property of wavelet packets in ..."

Interpolatory Wavelet Packets
"... In this note, we present a construction of interpolatory wavelet packets. Interpolatory wavelet packets provide a finer decomposition of the 2^j th dilate cardinal interpolation space, hence, give a better localization for an adaptive interpolation. This can lead to a more efficient compression sche ..."
