镜面反射曲面上高光的视差通常不同于曲面点的视差。A.Kirschmann(1895)提出，这一事实可以作为光泽知觉的双目线索。A.Blake和H.Bülthoff(1990)证实了这一点，他们发现，如果高光的视差接近物理正确的视差，受试者会认为凸椭球表面的光泽度是最逼真的。在这一发现的基础上，我们更仔细地研究了高光视差的效果是否取决于高光的锐度以及漫反射和镜面反射的相对量。我们测量了高光差异对光泽感知强度和感知真实性的影响。我们使用了复杂的三维曲面，这些曲面在CRT上立体呈现。使用Phong照明模型改变了反射特性。无论有无高光差异，都会呈现高光。在评级实验中，受试者被要求判断感知到的表面光泽度的强度和真实性。高光差异的存在导致感知光泽度的真实性和强度的增强。后一项发现在另一项配对实验中得到了证实。
The disparity of highlights on specular reflecting surfaces usually differs from the disparity of the surface points. A. Kirschmann (1895) proposed that this fact may be used as a binocular cue for gloss perception. This was confirmed by A. Blake and H. Bülthoff (1990) who found that subjects judged the glossiness of convex ellipsoidal surfaces as most realistic if the disparity of the highlights was close to the physical correct one. Extending on this finding, we investigate more closely whether the effect of highlight disparity depends on the sharpness of the highlight and the relative amount of diffuse and specular reflection. We measured the effect of highlight disparity on both perceived strength and perceived authenticity of gloss. We used complex, three-dimensional curved surfaces that were stereoscopically presented on a CRT. The reflection characteristics were varied using the Phong lighting model. Highlights were presented either with or without highlight disparity. In a rating experiment, subjects were asked to judge the strength and the authenticity of the perceived surface glossiness. The presence of highlight disparity lead to an enhancement of both the authenticity and the strength of perceived glossiness. The latter finding was confirmed in an additional matching experiment.
