摘要
This study fits within the framework of the diagnosis assistance and deals with the MR brain image types. To highlight the possibility of cerebral pathology such as tumours, one of the newest techniques of pattern recognition which exploits SOM (Self Organization Map) and LVQ (Learning Vector Quantization) algorithms of Kohonen is proposed. A short outline on these algorithms is brought back. Pre-processing adopted method is presented describing the training basis construction. Three classification approaches are carried out, comparative studies are conducted. The algorithm's proprieties are verified according to thėiteration number and the maps size. The classification quality is expressed via two parameters: the quantization error (QE%) and the good classification rate (CR%). Five pathological images and a healthy one arrested. The obtained results are in accordance with those of the results presented in the referred bibliographic. © 2008 Asian Network for Scientific Information.
