近年来，已经广泛地进行了使用图像分析的质量评估的研究。本研究的目的是建立彩色图像采集系统，使我们能够在标准漫射光源下准确地掌握目标物体的颜色，并利用CBIR技术对所获得的彩色图像进行颜色分析。作为CBIR技术，应用了使用CDE（颜色分布熵）的彩色图像分析CDE。为了验证实验图像采集系统的有效性，以珍珠为光滑物体。图像采集的对象也有光泽和无光泽，和一些农业材料。结果，对于无光泽的被检体，得到了清晰的表面图像，对于有光泽的被检体，得到了无光泽的表面图像。由于3个珍珠图像的周边部的色相分布不同，因此明确了定量等级评价的可能性。这种现象可能是由于珍珠的干涉色引起的。作为对该图像使用CDE的CBIR分析的结果，定量地验证了周边部分中的等级差异。
In these days, a research on quality assessment using the image analysis has been widely carried out. In this study, the purpose is to construct the chromatic image acquisition system which enables us to grasp the accurate color of the targeted object under the standard diffused illuminant, and to carry out the color analysis by the CBIR technique for obtained chromatic image. As the CBIR technique, color image analysis using CDE (Color Distribution Entropy), CDE was applied. In order to verify the experimental image acquisition system, pearl was used as the glossy object. Image acquisition was made also for the objects both with and without gloss, and some agricultural materials. As a result, clear surface image was obtained for the object without gloss, and the surface image without gloss for the object with gloss. Since hue distribution of the peripheral part is different among three pearl images, the possibility of the quantitative rank evaluation was clarified. This phenomenon might be caused by the interference color of pearl. As a result of CBIR analysis using CDE on this image, the difference of the rank was quantitatively verified in the peripheral part.
