A Novel Fourth Heart Sounds Segmentation Algorithm Based on Matching Pursuit and Gabor Dictionaries
نویسندگان
چکیده
In this paper we propose an efficient method for S4 heart sound segmentation based on the Matching Pursuit algorithm and Gabor Dicitonaries. An evaluation of this algorithm, through the use of different cardiac cycle events for S4 heart sound signals, showed a high performance, achieving a detection rate of 100% with the use of Gabor dictionary. The proposed method is practical, thus making it suitable for several applications such as signal compression and audio coding.

Adaptive multiresolution image coding with matching and basis pursuits
In recent years there has been a growing interest in representation and compression of signals by using dictionaries of basis functions other than the traditional dictionary of sinusoids. These new set of dictionaries include cosine packets, chirplets, Gabor functions, wavelets, and wavelet packets. In this paper Matching Pursuit and Basis Pursuit with finite dictionaries of convolutional splin...
متن کاملMultivariate matching pursuit in optimal Gabor dictionaries: theory and software with interface for EEG/MEG via Svarog
BACKGROUND Matching pursuit algorithm (MP), especially with recent multivariate extensions, offers unique advantages in analysis of EEG and MEG. METHODS We propose a novel construction of an optimal Gabor dictionary, based upon the metrics introduced in this paper. We implement this construction in a freely available software for MP decomposition of multivariate time series, with a user frien...
متن کاملRedundancy-Driven A Posteriori Matching Pursuit Quantization
This paper studies quantization error in the context of Matching Pursuit coded streams. The quantization noise is shown to depend on error on both coefficients and indexes. It is moreover influenced by the redundancy of the Matching Pursuit dictionary. A novel general formulation of the structural redundancy in overcomplete decompositions is shown to enhance the accuracy of classical redundancy...
متن کاملGoodwin & Vetterli : Matching Pursuit and Atomic Signal Models
The matching pursuit algorithm can be used to derive signal decompositions in terms of the elements of a dictionary of time-frequency atoms. Using a structured overcomplete dictionary yields a signal model that is both parametric and signal-adaptive. In this paper, we apply matching pursuit to the derivation of signal expansions based on damped sinusoids. It is shown that expansions in terms of...
متن کاملSulci Detection in Photos of the Human Cortex Based on Learned Discriminative Dictionaries
The use of discriminative dictionaries is exploited for the segmentation of sulci in digital photos of the human cortex. Manual segmentation of the geometry of sulci by an experienced physician on training data is taken into account to build pairs of such dictionaries. It is demonstrated that this approach allows a robust segmentation of these brain structures on photos of the brain as long as ...
