Abstract
A method and a system are provided for detection of seizures by applying advanced numerical analysis techniques to digitized waveforms of an electroencephalogram (EEG) recording. In an embodiment, the advanced numerical analysis techniques implemented in the method and system for detecting seizures include a combination of matching pursuit, neural network rules, and connected-object clustering algorithms.
Claims45
A method of detecting a seizure, comprising the steps of:
- a) dividing a digitized waveform of an electroencephalogram (EEG) recording into a plurality of epochs each having a first predetermined duration;
- (b) computing matching pursuit for a given one of the epochs to obtain a plurality of seizure atoms;
- (c) describing the seizure atoms and the given epoch with at least one neural network (NN) rule;
- (d) applying connected-object clustering to the epochs in a sliding window of a second predetermined duration to obtain a clustering result;
- and
- (e) establishing a seizure point from the clustering result.
A computer readable medium comprising a plurality of instructions, which when executed by a computer, cause the computer to perform the steps of:
- (a) dividing a digitized waveform of an electroencephalogram (EEG) recording into a plurality of epochs each having a first predetermined duration;
- (b) computing matching pursuit for a given one of the epochs to obtain a plurality of seizure atoms;
- (c) describing the seizure atoms and the given epoch with at least one neural network (NN) rule;
- (d) applying connected-object clustering to the epochs in a sliding window of a second predetermined duration to obtain a clustering result;
- and
- (e) establishing a seizure point from the clustering result.
An article of manufacture, including a computer readable medium having computer readable program code means embodied therein for detecting a seizure, the computer readable program code means in the article of manufacture comprising:
- (a) computer readable program code means for dividing a digitized waveform of an electroencephalogram (EEG) recording into a plurality of epochs each having a first predetermined duration;
- (b) computer readable program code means for computing matching pursuit for a given one of the epochs to obtain a plurality of seizure atoms;
- (c) computer readable program code means for describing the seizure atoms and the given epoch with at least one neural network (NN) rule;
- (d) computer readable program code means for applying connected-object clustering to the epochs in a sliding window of a second predetermined duration to obtain a clustering result;
- and
- (e) computer readable program code means for establishing a seizure point from the clustering result.
