使用广泛使用的线条图的轮廓，我们创建了面向研究轮廓整合和纹理分割的刺激，使用日常物体的形状。每个刺激都由Gabor元素组成，这些Gabor元素沿着物体的轮廓曲线定位和定向，嵌入在一个更大的均匀密度的Gabor阵列中。我们通过改变轮廓内外元素的方向，创建了六个版本的最终轮廓刺激。在两个实验中，参与者试图识别刺激中的物体，提供了可识别性和名称一致性的规范，并显示了刺激版本之间可识别性的差异。虽然我们的刺激集中单个对象之间存在很大的差异，但进一步的分析表明，许多刺激特性通常可以预测识别性能。我们的网站（http://www.gestaltrevision.be/sources/gaboroutlines）提供了刺激和伴随的规范数据，为进一步研究正常和临床人群的轮廓整合和纹理分割提供了有用的工具，特别是当自上而下对这些过程的影响，如熟悉物体的先验知识的作用，是主要的兴趣。
Using outlines derived from a widely used set of line drawings, we created stimuli geared towards the investigation of contour integration and texture segmentation using shapes of everyday objects. Each stimulus consisted of Gabor elements positioned and oriented curvilinearly along the outline of an object, embedded within a larger Gabor array of homogeneous density. We created six versions of the resulting Gaborized outline stimuli by varying the orientations of elements inside and outside the outline. Data from two experiments, in which participants attempted to identify the objects in the stimuli, provide norms for identifiability and name agreement, and show differences in identifiability between stimulus versions. While there was substantial variability between the individual objects in our stimulus set, further analyses suggest a number of stimulus properties which are generally predictive of identification performance. The stimuli and the accompanying normative data, both available on our website (http://www.gestaltrevision.be/sources/gaboroutlines), provide a useful tool to further investigate contour integration and texture segmentation in both normal and clinical populations, especially when top-down influences on these processes, such as the role of prior knowledge of familiar objects, are of main interest.
