【摘要】 颜色科学的理论与图像技术有着密切的联系,由于现代的色度学及色貌理论主要是建立在大尺寸、相互独立的均匀色块的视觉实验基础之上,对于存在着纹理结构的图像的应用会产生较大的偏差,所以本文提出对空间频率对色貌的影响进行研究,采用非对称匹配的视觉心理物理实验的方法来定量分析视觉的空间频率性质。本文介绍了视觉实验的设计方法和实验的一些结论。更多还原

【Abstract】 As we all know, color theory is broadly applied in the image technology. But the color theory including color appearance model is based on large uniform visual fields (two and ten degrees of viewing angle) and the color appearance of a stimulus is not independent of its spatial and temporal characteristics. If we want to apply the color appearance model to the image and be successful to predict the image color, we must understand the relationship between color and pattern. In the article, we recommend the asymmetric matching method to study the visual spatial characteristic and give some experiment results.更多还原
