The evaluation was made by statistical and texture analysis, as well as by optical perception by two vascular experts on 20 ultrasound images of carotid artery. The de-speckled filters used were based on: (i) local statistics, (ii) homogeneous mask area filters, and (iii) geometric filtering. Results showed that image quality was improved after de-speckle filtering for both scanners. | URI: | https://hdl.handle.net/20.500.14279/23657 | ISBN: | 0-7803-7667-6 | DOI: | 10.1109/ITAB.2003.1222492 | Rights: | © IEEE | Type: | Conference Papers | Affiliation : | Intercollege University of Cyprus Cyprus Institute of Neurology and Genetics Brunel University |
