The following procedure was investigated on 230 images (recorded from 115 symptomatic, and 115 asymptomatic subjects): (i) six different de-speckle filters were used based on first order and higher order local statistics, anisotropic diffusion, and geometric properties; (ii) nine different texture feature sets were extracted, and (iii) the k-nearest neighbor classifier was used to classify a plaque as symptomatic or asymptomatic. The de-speckle filters based on higher order statistics, anisotropic speckle diffusion, and geometric properties gave a slightly higher percentage of correct classifications score than the original images. | URI: | https://hdl.handle.net/20.500.14279/22840 | ISBN: | 0-7803-7612-9 | DOI: | 10.1109/IEMBS.2002.1106259 | Type: | Conference Papers | Affiliation: | Cyprus Institute of Neurology and Genetics Intercollege University of Cyprus University of New Mexico |
