2d Wavelet Packet Analysis in Adaptively Chosen Basis

Calling Sequence

[bb,stats,coef] = WP2dTour(img,MaxDeep,qmf[,titlestr])

Parameters

Inputs:

img :

2-d image; size n by n, n dyadic

MaxDeep:

integer; limit on max depth of tree in best basis search

qmf :

quadrature mirror filter

titlestr:

string; name of signal

Outputs:

bb :

basis quadtree of best basis

stats :

stat quadtree of best basis

coef :

coefficients in best basis

Description

Perform an adaptive wavelet packet analysis on the given image, selecting the best basis and then plotting the WP coefficients for this basis along with the image overlaid by its 2-d partition.
