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.

SaivDr Package (http://www.mathworks.com/matlabcentral/fileexchange/45084-saivdr-package) contains fast and stable implementation of DirLOTs. Please see the folder 'examples/dirlot' in the package.
