Mart ́ınez-Trinidad et al PY - 2006// TI - Linear Radial Patterns Characterization for Automatic Detection of Tonic Intestinal Contractions T2 - LNCS BT - 11th Iberoamerican Congress on Pattern Recognition SP - 178–187 VL - 4225 PB - Springer Verlag CY - Berlin Heidelberg N2 - This work tackles the categorization of general linear radial patterns by means of the valleys and ridges detection and the use of descriptors of directional information, which are provided by steerable filters in different regions of the image. We successfully apply our proposal in the specific case of automatic detection of tonic contractions in video capsule endoscopy, which represent a paradigmatic example of linear radial patterns.
