continuous K-SVD

A parallelized C++ implementation of K-SVD and 2D continuous K-SVD, using Eigen3 and OpenMP. Project written in Qt.

In the case of 2D continuous K-SVD, discrete atoms are replaced with 'continuous atoms' represented as linear combinations of products of cosines mapping from a 2D coordinate plane.

This allows sparse coding of continuous sampled signals or unstructured signals of variable length as values sampled at locations in a 2D plane, as well as predicting signal values away from the sampled locations.
