Abstract

In the natural environment, we are attracted to pleasant stuffs such as fur and jewels, and turn away from unpleasant stuffs such as decaying matter and gatherings of small insects. Increasing evidence for the dependence of human preferences and aesthetic judgments on simple image features implies that such affective responses to natural surfaces and textures are related to specific image statistics. Using 194 diverse natural surfaces and their statistically synthesized images, the present study examined if and how ratings of pleasantness − unpleasantness are related to low-level image statistics. The results showed that human observers gave similar emotional ratings for natural images and for Portilla-Simoncelli synthesized images. The perceived surface properties such as glossiness, bumpiness, and translucency showed no or little correlation with the emotional ratings and were degraded in synthesized stimuli. The analysis of surface images revealed that the emotional ratings were related to a small set of low-level image statistics, such as excessive power at specific spatial frequencies and cross-orientation energy correlation. The results suggest the critical role of low-level image statistics in affective responses to natural surfaces and textures.

视觉上的愉悦和自然表面的不愉悦

在自然环境中，我们喜欢皮毛和珠宝等令人愉快的东西，而不喜欢腐烂的物质和小昆虫的聚集等令人不快的东西。越来越多的证据表明，人类的偏好和审美判断依赖于简单的图像特征，这意味着对自然表面和纹理的情感反应与特定的图像统计有关。本研究使用194种不同的自然表面和它们的统计合成图像，研究了愉快-不愉快的等级是否以及如何与低级图像统计相关。结果表明，人类观察者对自然图像和波蒂拉-西蒙切利合成图像给出了相似的情感评级。感知到的表面特性，如光泽度、凹凸度和透明度，与情绪评级没有或很少相关，并且在合成刺激下降低了。对表面图像的分析表明，情绪评分与一小组低水平图像统计相关，如特定空间频率下的过度功率和交叉定向能量相关。结果表明，低水平图像统计在对自然表面和纹理的情感反应中起着关键作用。

期刊介绍： Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
