MATLAB class definitions for directional lapped orthogonal transforms

| Watch this File

File Information
Description

This toolbox provides MATLAB class definitions for design and evaluation of 2-D nonseparable directional lapped orthogonal transforms (DirLOTs). The DirLOTs are based on a lattice structure consisting of the 2-D separable block-DCT and non-separable support-extension processes and has a special feature to simultaneously satisfy the fixed- critically-subsampling, overlapping, orthogonal, symmetric, real-valued and compact-support property.
