Recursive construction of biorthogonal polynomials for handling polynomial regression
Laura Rebollo-Neira, Jason Laurie
An adaptive procedure for constructing polynomials which are biorthogonal to the basis of monomials in the same finite-dimensional inner product space is proposed. By taking advant…
Simultaneous Optimized Orthogonal Matching Pursuit with Application to ECG Compression
Laura Rebollo-Neira
A greedy pursuit strategy which finds a common basis for approximating a set of similar signals is proposed. The strategy extends the Optimized Orthogonal Matching Pursuit approach…
Sparsity based morphological identification of heartbeats
Laura Rebollo-Neira, Khalil Battikh, Amadou Sidi Watt
The electrocardiogram (ECG) is one of the most common primary tests to evaluate the health of the heart. Reliable automatic interpretation of ECG records is crucial to the goal of…
Enhancing sparse representation of color images by cross channel transformation
Laura Rebollo-Neira, Aurelien Inacio
Transformations for enhancing sparsity in the approximation of color images by 2D atomic decomposition are discussed. The sparsity is firstly considered with respect to the most si…
Construction of wavelet dictionaries for ECG modelling
Dana Cerna, Laura Rebollo-Neira
The purpose of sparse modelling of ECG signals is to represent an ECG record, given by sample points, as a linear combination of as few elementary components as possible. This can…
Mixed-transform based codec for 2D compression of ECG signals
Johan Chagnon, Laura Rebollo-Neira
A method for ECG compression, by imaging the record as a 2D array and implementing a transform lossy compression strategy, is advanced. The particularity of the proposed transforma…
