Construction Feature of Intrinsic Color Vector Span Space on Appearance of Tibetan Traditional Architecture from Digital Images

Abstract

This article is focused on the qualitative analysis in the color art analysis of Tibetan traditional architecture(TTA) while lack of quantitative analysis, the definitions of visual distinguishable function, color vector distinguishable level and intrinsic color vector span distinguishable space(ICVSS) are introduced firstly, method for ICVSS is put forward by these definitions and simple set operation about TTA, which is used as the main manifestation of the color features of the TTA. Finally, numerical tests are implemented with the digital images and color point cloud data set is inputted by Matlab programming. The experiments are proved that the method is simple, accurate and effective, and agree with the works of the existing qualitative analysis.
