Research on visual texture perception in the last decades was often devoted to segmentation and region segregation. In this report, I address a different aspect, that of texture identification and similarity ratings between texture fields with different texture properties superimposed. In a series of experiments, I noticed that certain feature dimensions were considered as more important for similarity evaluation than others. A particularly low ranking is given to orientation. This paper reports data from two test series: a comparison of color and line orientation and a comparison of two purely spatial properties, texture granularity (spatial frequency) and texture orientation. In both experiments, observers tended to ignore orientation when grouping texture patches for similarity and instead looked for similarities in the second dimension, color or spatial frequency, even across different orientations.
过去几十年中，视觉纹理感知的研究常常致力于分割和区域分离。在本报告中，我探讨了一个不同的方面，即叠加有不同纹理属性的纹理场之间的纹理识别和相似性评级。在一系列实验中，我注意到某些特征维度在相似性评估中被认为比其他维度更重要。其中，方向的重要性排名特别低。本文报告了两个测试系列的数据：颜色与线条方向的比较，以及两个纯空间属性——纹理粒度（空间频率）和纹理方向的比较。在这两个实验中，观察者在对纹理块进行相似性分组时往往会忽略方向，而是在第二个维度（颜色或空间频率）中寻找相似性，即使跨越不同方向也是如此。
