视觉复杂性作为图像的一个与人类感知有关的属性，在计算机科学和心理学领域得到了广泛的研究。在传统的研究中，研究对象仅限于传统的二维图案或图像。因此，如果在这个场景中引入深度信息，它将如何影响我们对图像视觉复杂性的感知？为了回答这个问题，我们开发了一个实验性的虚拟现实系统，可以控制和显示三维（3D）视觉刺激。在这项研究中，我们的目的是探讨深度信息对视觉复杂性知觉的影响，通过比较二维和三维显示相同的刺激。我们扫描了三种具有不同特征的纹理来创建实验刺激，并招募了25名参与者进行实验。结果表明，深度信息显著增加了纹理图像的视觉复杂性感知。此外，深度信息对不同纹理的视觉复杂度有不同程度的影响。在3D图像中引入的最大深度越高，视觉复杂度感知的增加就越显著。本研究所使用的实验虚拟现实系统也为以后的实验提供了可行的实验工具。
Visual complexity, as an attribute of images related to human perception, has been widely studied in computer science and psychology. In conventional studies, the research objects have been limited to the traditional two-dimensional (2D) patterns or images. Therefore, if depth information is introduced into this scenario, how will it affect our perception of visual complexity of an image? To answer this question, we developed an experimental virtual reality system that enables control and display of three-dimensional (3D) visual stimuli. In this study, we aimed to investigate the effect of depth information on visual complexity perception by comparing 2D and 3D displays of the same stimuli. We scanned three textures with different characteristics to create the experimental stimuli and recruited 25 participants for the experiment. The results showed that depth information significantly increased the visual complexity perception of the texture images. Moreover, depth information had different degrees of impact on visual complexity for different textures. The higher the maximum depth introduced in the 3D image, the more significant the increase in visual complexity perception. The experimental virtual reality system used in this study also provides a feasible experimental tool for future experiments.
