Invariant

This transformation is non-redundant, approximately shift-invariant and produces oriented filters in 2D and 3D. There is a m-file called 'example.m' which shows how one can use this package.For more information see the following paper:Hosseini, Vafadust : "Almost Perfect Reconstruction Filter...

All methods on this heap preserve the heap property invariant; therefore there is no need for is_heap(). When creating a new heap, an optional 'key' argument can be specified to determine the comparison key for the items to be pushed into the heap. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This library aims to provide support for D-dimensional images in Java and to enable high-level implementation of algorithms in dimensionally-invariant manner. Major features: the dimensionality and the access to primitive data types are abstracted. Platforms: Windows, Mac, Linux

Y = DCTN(X) returns the discrete cosine transform (DCT) of X.X = IDCTN(Y) returns the inverse discrete cosine transform (IDCT) of Y.Y = DSTN(X) returns the discrete sine transform (DST) of X.X = IDSTN(Y) returns the inverse discrete sine transform (IDST) of Y.X and Y can be N-dimensional.D =...

Linear feedback shift registers (LFSR) are a simple method of generating sequences, including pseudorandom number sequences. The LFSR code provided is very unrestricted, allowing for any feedback polynomial, initial state or decimation factor. The code is written for a 32 bit LFSR, but minor... Platforms: Matlab

This toolbox implements the methods of [1] and [2] to design H-infinity controllers for linear spatio-temporally invariant, or multidimensional (MD), systems. Utilities are also provided for the following types of operations on MD systems:1. System description (MD systems are specified via a... Platforms: Matlab
