Highly Nonlinear Approximations for Sparse Signal Representation
Nonuniform Spline Dictionaries:
- CutDic produces a non-uniform B spline dictionary
- NonBSpline Computes the value of B spline basis at x0 by the recurrence formula for the non-uniform B spline
- NonUniB computes all non-unfirom B spline over the partition 'p'
- ProducePartition using the curvature of the signal f, it compute the knots of a partition
All the presented routines are described in detail in our manual (ps,pdf).
