This is the readme file for the PDTDFB toolbox, which is a shiftable pyramidal decomposition ( see references ). Many functions are developped based on the contourlet toolbox available at http://www.ifp.uiuc.edu/~minhdo/software/. Some of the functions in the contourlet toobox are rewritten in this toolbox. We also use some functions from the shiftable pyramid toolbox at http://www.cns.nyu.edu/~lcv/software.html This is the list of main functions. For syntax of each function, see the content of the m files LEVEL 1 * The two main PDTDFB decompostion and reconstruction functions PDTDFBDEC : Pyramid Dual Tree Directional Filterbank Decomposition PDTDFBREC : Pyramid Dual Tree Directional Filterbank Reconstruction PDTDFBDEC_F Pyramid Dual Tree Directional Filterbank Decomposition using FFT at the multresolution FB and the first two level of dual DFB tree PDTDFBREC_F Pyramid Dual Tree Directional Filterbank Reconstruction using FFT at the multresolution FB and the first two level of dual DFB tree LEVEL 2 * DFB decomposition and reconstruction functions TDFBDEC : DFB decomposition with phase correction at each stage of the tree TDFBREC : DFB reconstruction with phase correction at each stage of the tree TDFBDEC_L : Directional Filterbank Decomposition using Ladder Structure TDFBREC_L : Directional Filterbank Reconstruction using Ladder Structure LPREC : Pyramid Decomposition LPDEC : Pyramid Reconstruction LEVEL 3 * Two channel FB decomposition and reconstruction FBDEC Two-channel 2D Filterbank Decomposition FBREC Two-channel 2D Filterbank Reconstruction FBDEC_L Two-channel 2D Filterbank Decomposition using Ladder Structure FBREC_L Two-channel 2D Filterbank Reconstruction using Ladder Structure SUPPORT FUNCTIONS * Resampling functions BACKSAMP REBACKSAMP RESAMP PUP PDOWN DUP DDOWN QUP QDOWN QPDEC QPREC PPDEC PPREC * Utility functions PDTDFB_WIN FUN_MEYER ANG_PDFB : Return the angle of the direction of the filter in radian PDFB_ANG : Return the directional filter that the angle fall into SNR * Filters functions DFILTERS LDFILTER MCTRANS PFILTERS FFILTERS * Signal manipulation MKZERO_PDTDFB : Make a data structure similar to a PDTDFB decomposition filled with zeros INTERPFILT : Interpolation based on digital filter PDTDFB2VEC VEC2PDTDFB FITMAT MODULATE2 EXTEND2 PERIODIZE *Convolution and filtering SEFILTER2 EFILTER2 FCONV2 DEMO SCRIPTS DEMO_PDTDFB_F DEMO_DENOISE
