Removing Specular Components of Image Sequences based on EPI Analysis

چکیده
This paper describes a method, which removes specularities from image sequences taken by a video camera in uniform straightly-line motion. Specular components, especially strong highlights, raise some problems in object recognition. Based on spatio-temporal image analysis, we are able to detect specular components and reconstruct original texture on the body as diffuse components. Analyzing the motion of specular components in EPIs (Epipolar Plane Images), we can distinguish specularities from ordinary texture. Some experiments have been conducted using our methods, and the results show the effectiveness the method to remove specularities from image sequences. Moreover, even if texture on a body is hidden by strong highlights, this method recovers the original texture.

Extracting layers and analyzing their specular properties using epipolar-plane-image analysis
Despite progress in stereo reconstruction and structure from motion, 3D scene reconstruction from multiple images still faces many difficulties, especially in dealing with occlusions, partial visibility, textureless regions, and specular reflections. Moreover, the problem of recovering a spatially dense 3D representation from many views has not been adequately treated. This document addresses t...
متن کاملDiffuse-Specular Separation and Depth Recovery from Image Sequences
Specular reflections present difficulties for many areas of computer vision such as stereo and segmentation. To separate specular and diffuse reflection components, previous approaches generally require accurate segmentation, regionally uniform reflectance or structured lighting. To overcome these limiting assumptions, we propose a method based on color analysis and multibaseline stereo that si...
متن کاملProcessing Specular Reflection Components of Chrome-plated Surface by Multi-Image Reconstruction Method
Chrome-plated surfaces are perfectly specular, in which the diffuse reflection components are weak while the specular reflection components are so strong that their intensities saturate the CCD matrix and cause some surface features to be lost. This situation means that one image alone cannot show all of the surface features. To process specular reflection components, we proposed a novel multi-...
متن کاملEvaluation of Sensory Pathways in Spinal Cord by Comparison of fMRI Methodologies
Introduction: Today, clinicians and neuroscientists need to have a comprehensive survey of neurological pathologies and injuries. For the First-time, SEEP contrast and Spin-Echo pulse sequences was used for functional imaging of the Lumbar spinal cord. This method used by several research groups for Spinal cord mapping, but other researchers tried to improve BOLD fMRI to Spina...
متن کاملMotion of specularities on low-relief surfaces: frequency domain analysis
Typical studies of the visual motion of specularities have been concerned with how to discriminate the motion of specularities from the motion of surface markings, and how to estimate the underlying surface shape. Here we take a different approach and ask whether a field of specularities gives rise to motion parallax that is similar to that of the underlying surface. The idea is that the causti...
