The Investigation of Color Image Context and Configuration Affecting Perceptually Uniform of Color Evaluation Based on CIE Color Spaces - Using Natural Scenery Images as Tested Samples
In recent years, most researches focused on developing mathematical methods to calculate principle color component value and color difference of tested images, but without any explicit description regarding their characteristics, classifications, and compositions. However, CIE recommended color spaces can be applied to predict which spectral power distributions perceived as the same color which is not particularly perceptually uniform. A preliminary study was conducted to evaluate the precision of calculation of principle component color between CIE color spaces via using natural scenery color images as test samples. A group of 51 natural scenery color images with similar context and configuration were selected. An image analysis tool, ColorSpace Convertor, was developed to analyze ΔE between two sets of tested color images. The experimental results indicated that there were existed significant variations of the principle color component values of those images between CIEL*a*b* and CIEL*u*v* color spaces. The largest color difference about 38 in terms of CIEL*a*b* unit occurred between evaluated results has been found. It is suggested that the color images with similar context and configuration did not reach perceptually uniform between CIE recommended color spaces.
