Abstract(in English) Abstract This paper discusses effect of grouping based on self-organising map.The SOM is a one of unsupervisedlearning neural network,and is commonly used to form clusters using its topology preserving nature.Therefore the SOM is used for various pattern recognition applications.In image recognition,it’s recognition accuracyis degraded under difficult lighting conditions.This paper proposes a new image recognition system thatemploys a grouping method.The proposed system consists of grouping of vectors according to their brightness,and vector classification that is carried out in the assigned group.Each group tunes recognition parameters forthe vectors belonging to the group.The proposed method is applied to position identification from omnidirectionalimage.The experimental results show that the system can run at 92.8% of recognition rate.
