Multi-counterpropagation network model for colour recognition


Yaakob, Razali and Sulaiman, Md. Nasir and Mahmod, Ramlan and Tengku Muda Mohamed, Mahmud and Ramli, Abd Rahman (1999) Multi-counterpropagation network model for colour recognition. Malaysian Journal of Computer Science, 12 (1). pp. 38-46. ISSN 0127-9084


Minolta Chroma Meters was used to convert colours into numbers. It offers five different colour systems for measuring absolute chromaticity, that is, CIE Yxy, L*a*b*, L*C*H°, Hunter Lab and XYZ. In this study, only L*a*b* is used, and combinations of two counterpropagation network (CPN) are required to recognise 808 colours produced by The Royal Horticultural Society, based on RHS Colour Chart [1]. Our proposed neural network model is tested; the result shows that 99% of trained data are recognised, against 98% for untrained data.
