Abstract
This paper studies the classification of the International Commission on Illumination (CIE) standard skies using sky luminance and other climatic parameters measured in Hong Kong. An approach to identify the standard skies is proposed. The performance of the proposed approach and the Bartzokas et al. method was evaluated against the measured data in terms of root-mean-square error (RMSE). The statistical analysis revealed that using the Bartzokas et al. method, around 50% of the data were rejected for sky classification and the overall RMSE was calculated of around 34%. The proposed approach produced an overall RMSE of just less than 33% without data reduction.
