Abstract
We applied Kohonen's SOMs (Self Organizing feature Map) in the color matching problem in the combination of fifteen buttons and cloths. The chromaticity of cloth's color is measured by the method based on CIE-Lab. Each distribution of fifteen buttons is represented and formed by three SOMs on each two dimensional projected plane. From the observation of these SOMs, we confirm that each distribution of fifteen buttons has many mutually overlapping regions. In this situation, we propose a method of classification that have characteristics of ranking by adaptation in each button's SOM, and test the performance of our method using practical data. From the results, we obtained over 87% correct judgement, which is defined as correspondence of teacher's class with one of the class in the best three by our method. Also our method and LVQ obtained almost the same recognition rate about the best answer.
