Key characteristics of specular stereo.
Because specular reflection is view-dependent, shiny surfaces behave radically differently from matte, textured surfaces when viewed with two eyes. As a result, specular reflections pose substantial problems for binocular stereopsis. Here we use a combination of computer graphics and geometrical analysis to characterize the key respects in which specular stereo differs from standard stereo, to ...
متن کاملSpecular Stereo
A glossy highlight, viewed stereoscopically, can provide information about surface shape. For example, highlights appear to lie behind convex surfaces but in front of concave ones. A highlight is a distorted, reflected image of a light source. A ray equation is developed to predict the stereo disparities generated when a point source of light is reflected in a smooth, curved surface. This equat...
متن کاملStereo and Specular Reeection
The problem of accurate depth estimation using stereo in the presence of specular reeection is addressed. Specular reeection, a fundamental and ubiquitous reeection mechanism, is viewpoint dependent and can cause large intensity diierences at corresponding points, resulting in signiicant depth errors. We analyze the physics of specular reeection and the geometry of stereopsis which lead to a re...
متن کاملStereo in the Presence of Specular Reeection
The problem of accurate depth estimation using stereo in the presence of specular reection is addressed. Specular re ection is viewpoint dependent and can cause large intensity di erences at corresponding points. Hence, mismatches can result causing signi cant depth errors. Current stereo algorithms largely ignore specular re ection which is a fundamental re ection phenomenon from surfaces, bot...
متن کاملBinocular Stereo in the Presence of Specular Re ectionDinkar
We address the problem of accurate depth estimation using stereo in the presence of specular reeec-tion. Specular reeection is viewpoint dependent and can cause large intensity diierences at corresponding points in stereo images. Hence, mismatches could result causing signiicant depth errors. Our approach seeks to determine a scene independent optimal stereo connguration such that intensity mis...
