Abstract

Face recognition from 2D images is influenced by various factors, including lighting conditions, viewing direction, rotation, and polarity inversion. It has been proposed that these techniques affect face recognition by distorting shape from shading. This study investigates the perception of 3D face shape in 2D images using a gauge figure task. Two experiments were conducted where participants adjusted a gauge figure across multiple locations within a 3D image to assess its surface structure. We manipulated face orientation, lighting direction, and polarity inversion (exp 2). While these manipulations resulted in variations from the true surface structure, they could be explained by an affine transformation. This suggests that the perception of the intrinsic 3D shape of faces is stable across these image manipulation techniques. The effects of viewing conditions on face recognition may thus be better interpreted through their influence on the perception of material properties such as pigmentation, or on information closer to the level of the retinal image itself.

感知到的人脸的内在三维形状对光照方向、图像旋转和极性反转的变化具有鲁棒性。

从二维图像中识别人脸受到多种因素的影响，包括光照条件、观看方向、旋转和极性反转。有人提出，这些技术通过从阴影中扭曲形状来影响人脸识别。本研究通过测量图形任务研究了在二维图像中对三维脸型的感知。在两个实验中，参与者在3D图像的多个位置调整一个测量图形，以评估其表面结构。我们操纵了面取向、光照方向和极性反转（实验2）。虽然这些操作导致了真实表面结构的变化，但它们可以用仿射变换来解释。这表明，在这些图像处理技术中，对面部内在3D形状的感知是稳定的。因此，观看条件对人脸识别的影响可以通过它们对物质特性（如色素沉着）或更接近视网膜图像本身水平的信息的感知的影响来更好地解释。

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.
