In this paper, we present a new method to deal with specular highlights in correspondence search. The proposed method is essentially based on the specular-free two-band image that we introduce to deal with specular reflection. For given input images, specular-free two-band images are generated using simple pixel-wise computations in real-time. Specular-free two-band images are then used to comp...

A new method for determining the shape of specular surfaces is presented in this paper. Our approach reconstructs the shape of specular surfaces from a relationship between the surrounding environment and the observed images of specular surfaces. A prototype system has been implemented. The experimental results show that the proposed method is effective to the reconstruction of specular objects...

When a curved mirror-like surface moves relative to its environment, it induces a motion field—or specular flow—on the image plane that observes it. This specular flow is related to the mirror’s shape through a non-linear partial differential equation, and there is interest in understanding when and how this equation can be solved for surface shape. Existing analyses of this ‘shape from specula...

Specular flow is an important class of optical flow whose utility in visual tasks has gained much interest in contemporary vision research. Unfortunately, however, reliably estimation of specular flow from image sequences is an open question that was never addressed formally before. In this paper we first argue that existing optical flow algorithms are incapable of reliable specular flow estima...

For dielectric inhomogeneous objects, the perceived reflections are the linear combinations of diffuse and specular reflection components. Specular reflection plays an important role in the fields of image analysis, pattern recognition, and scene synthesis. Several methods for the separation of the diffuse and the specular reflection components have been presented based on image segmentation or...

In this letter a recursive and computationally efficient new formula for bit error rate (BER) in multipath channels with several specular components is derived. Using Jensen’s inequality it is shown that one specular component, Rice fading, provides the lowest possible BER. Using Lagrange multipliers to solve a constrained optimization problem, it is further shown that for two specular componen...

An X-ray reflectometer for simultaneous measurement of specular and off-specular reflection of liquid surfaces is described. The reflectometer, equipped with a two-dimensional single X-ray photon-counting pixel array detector obtained the full range of X-ray specular and off-specular reflections in an extremely short time (1 s). Both the specular and off-specular reflection of water exhibited g...

In general, the evaluation of automotive coatings appearances favors (is considered preferentially) more than chemical and physical properties. Therefore, its improvement is most required. Studying appearance by means of QMS-BP technique, in which it measures some of the most important coating appearance factors, such as: the specular gloss, distinctness of image (DOI) and orange peel. In this ...
