The specular reflection appears as white area on the cervical images that covers certain region of the images. It affects the quality of the cervical images causing difficulty for the physician to analyse the smart colposcopy images. In this paper, ...

Texturing is a ubiquitous technique used to enrich surface appearance with fine detail. While standard filtering approaches, such as mipmapping or summed area tables, are available for rendering diffuse reflectance textures at different levels of detail,...

We study the Cucker--Smale (C-S) type model in a cylindrical domain with a specular reflection boundary condition. When there exist flocking forces along the normal direction to the boundary, then a “sticky wall" effect is numerically observed such that ...

The specularity prediction task in images, given the camera pose and scene geometry, is challenging and ill-posed. A recent approach called JOint LIght-MAterial Specularity (JOLIMAS) addresses this problem using a geometric model under the assumption ...

Shape from shading with multiple light sources is an active research area, and a diverse range of approaches have been proposed in recent decades. However, devising a robust reconstruction technique still remains a challenging goal, as the image ...

This paper proposes a pixelwise photometric stereo method for object surfaces with general bidirectional reflectance distribution functions (BRDFs) via appropriate reflection modeling. The modeling is based on three general characteristics of reflection ...

In this paper we provide sharp criteria for linear stability or instability of equilibria of collisionless plasmas in the presence of boundaries. Specifically, we consider the relativistic Vlasov--Maxwell system with specular reflection at the boundary for ...

3D reconstruction with specular reflection remover is one of the vital and robust tools that provide aid in many fields, especially medical filed. This article presents a novel method for reconstruction a real human heart surface from a single view ...

A enhancement is described for a previously proposed method for preventing unauthorized copying of information shown on a display [1]. Our previously proposed method utilizes the difference in spectral sensitivity between humans and imaging devices. A ...

When the radio waves propagate over the sea, the sea surface can be assumed smooth surface in case the frequency and the grazing angle achieve some certain conditions. The main parameters for describing the sea surface include the effective height of ...

Polarization is physical phenomena of the light which gives rich information of the scene even though it is undetectable by human eyes. In this paper, we analyze the polarization state of the light reflected on black specular objects in order to ...

Traditional dietary assessment methods, consisting of written and orally reported methods, are not widely acceptable or feasible for everyday monitoring. The development of built-in cameras for mobile devices provides a new way of collecting dietary ...

We previously proposed using infrared (IR) LEDs to corrupt recorded content to prevent the re-recording of images displayed on a screen. This method is based on the difference in sensory perception between humans and devices and prevents re-recording by ...

We provide a novel specular highlight removal method using reflection component separation and joint bilateral filtering. In general, highlights in images can be represented as the linear combination of diffuse and specular reflection components in ...

Based upon a new correspondence matching invariant called illumination chromaticity constancy, we present a new solution for illumination chromaticity estimation, correspondence searching, and specularity removal. Using as few as two images, the core of ...

This paper presents a solution for the photorealistic rendering of synthetic objects into dynamic real scenes, in Augmented Reality applications. In order to achieve this goal, an Image Based Lighting approach is used, where environment maps with ...

In this paper, we develop a numerical scheme for the interface problem in the planar symmetric radiative transfer equation with isotropic scattering. Such problems arise in the modeling of the propagation of energy density for waves in heterogeneous ...

This paper presents mathematical modelling and computer simulation of interior lighting systems. The point-by-point method is modified to include room surface reflectance to achieve more computational accuracy. The reflection of room surfaces added to ...

A method is described to reproduce reflection properties at the surface of real objects using spectral images, which are often saturated because of the limited dynamic range of image detectors. Reflection components are separated into diffuse and ...

Based on IBMR techniques, this paper study energy distribution of reflection light from object surface and a method is presented to separate elements of specular and diffuse reflection in an image. The ray projected from object surface to images ...
