Vestibulo-ocular Reflex Signal Processing Using Evolutionary Algorithm

Original language description

Vestibulo-ocular reflex (VOR) is an important source of diagnostic information for physicians. By analyzing it, they can recognize many disorders of the vestibular organ. The VOR signal is a response of the vestibular organ to the so called head rotationtest. It is measured by tracking the eye movements, which are, however, distorted by saccades. After filtering the saccades out we are left with discontinuous signal segments. This paper presents an approach to align them to form a smooth signal with the same frequencies that were originally present in the source signal. The approach is based on a direct estimation of the signal component parameters. Two methods of direct search are compared.the Nelder-Mead simplex search and the evolutionary strategywith covariance matrix adaptation. The experimental evaluation on signals with 1 to 5 components revealed that the evolutionary strategy is more robust, scalable and reliable method
