One of texture component on objects and graphics is luminance. By strength of luminance, human visual perception for clarify and material feeling of object surface is changed. It is important for texture evaluation such as this by appearing of 4K, 8K image quality display and content, high-definition digital broadcasting. Thus far, there were the difference meaning and interpretation for definition of "Shitsukan". Therefore, there were many studies whether "Shitsukan" can be evaluated quantitatively or not. As one of the past our study, we carried out texture analysis for classification method of texture types by using the Shitsukan Research Database. As a result, we were able to see characteristics between contrast and correlation for texture types. However, it was not enough to adapt for luminance information in the Shitsukan Research Database. In this paper, we analyzed statistically after comparing between texture analysis result and luminance information in the Shitsukan Research Database for the free of charge obtained from Web. And then, we discussed characteristics of texture types. |
