摘要： 针对扭曲视错服装外观图像缺乏客观评价方法的问题，将Tamura纹理特征用于扭曲视错服装的研究。文章首先确定106幅视错图案;从中挑选一幅，通过改变线条宽度、旋转扭曲角度和颜色参数进行二次设计，得到图案195幅，共计301幅;运用CLO 3D虚拟试衣软件模拟着装效果，并获取视错服装图像;计算出服装图像的Tamura纹理特征，邀请被试者对前106幅图案的服装图像进行主观评价。结果表明：Tamura纹理特征可用于视错服装的客观评价;视错图案的旋转扭曲角度对纹理特征的影响最大，颜色G值分量的影响次之，线条宽度影响最小。

Abstract： Aiming at the problem of lacking objective evaluation methods for distorted illusion clothing appearance images， the Tamura texture feature was used in the research of distorted illusion clothing. First， 106 optical illusion patterns were selected; One of them was selected for a secondary design， and 195 patterns were obtained by changing the line width， rotation twist angle and color parameters. There were 301 experimental patterns in total. CLO 3D virtual fitting software was used to simulate the dressing effect， and the image of illusion clothing was obtained; then the Tamura texture characteristics of the clothing image were calculated， and the subjects were invited to subjectively evaluate the clothing images of the first 106 patterns. The results have shown that Tamura texture features can be used for the objective evaluation of distorted illusion clothing; the twist angle of the distorted illusion pattern has the greatest influence on the texture features， followed by the G value component of the color， and the line width has the least influence.

Key words： illusion clothing; visual effect; objective evaluation; virtual fitting; Tamura texture features

视错作为视觉感知的一种特殊形式，是服装设计中重要的设计元素与设计手段。其中扭曲错觉[1]是把规则的点、线、面等结构元素感知为歪曲结构的现象[2]，被广泛地运用到服装设计中，来增加服装的趣味性与艺术性[3]。时装秀场上经常能看到扭曲视错设计的身影，在简单的服装款式上设计不同的黑白条纹或无法聚焦视线的几何图案，结合人体曲线与服装分割线产生扭曲错觉，突出服装的艺术效果。合理地利用视错觉图案进行服装设计，不仅可以修饰形体，而且能与服装结构相互补充[4]。……
