This article presents an investigation study of stereo-based 3D surface reconstruction algorithms by providing an overview of the diierent approaches that have been investigated in the stereo literature during the last decade. This study considers only the two-views plain stereo algorithms and provides another classiication for the stereo approaches based on the features used in the stereo lite...

In this paper, we exploit two characteristics of stereoscopic vision: the pop-out effect and the comfort zone. We propose a visual saliency prediction model for stereoscopic images based on stereo contrast and stereo focus models. The stereo contrast model measures stereo saliency based on the color/depth contrast and the pop-out effect. The stereo focus model describes the degree of focus base...

Time-lapse stereo – using natural illumination changes in stereo reconstruction for large scale outdoor scene is yet an unexplored application of spacetime stereo framework. In this project, we collect several time-lapse stereo data sets for further research use and also evaluate the performance of time-lapse stereo by comparing the quality of its disparity images to the ones using classic ster...

The performance of depth reconstruction in binocular stereo relies on how adequate the predefined baseline for a target scene is. Wide-baseline stereo is capable of discriminating depth better than the narrow-baseline stereo, but it often suffers from spatial artifacts. Narrow-baseline stereo can provide a more elaborate depth map with fewer artifacts, while its depth resolution tends to be bia...

OBJECTIVES To compare the differences between conventional radiography and digital computerized radiography (CR) in patients presenting to the emergency department. METHODS The study enrolled consecutive patients presenting to the emergency department who needed chest radiography. Quality score of the radiogram was assessed with visual analogue score (VAS-100 mm), measured in terms of millime...

RATIONALE, AIMS AND OBJECTIVES The process of transferring older, vulnerable adults from an elder care facility to the hospital for medical care can be an emotionally and physically stressful experience. The recent development of modern mobile radiography may help to ease this anxiety by allowing for evaluation in the nursing home itself. Up until this point, no health economic evaluation of th...

In this paper we describe different techniques of rendering stereo scenes in real-time. We discuss the physical properties of the given stereo setup and revise some basics knowledge needed for generating the stereo pairs. After that we discuss several techniques for rendering stereo pairs according to correctness. We explain certain effects and their appearance in a stereo rendered scene. Final...

Stereo image is frequently used as preprocessing of stereo vision techniques. Although stereo image rectification is performed using look-up tables which are computed in advance, it takes a long time to do rectification transformation on mobile platforms. Thus stereo image rectification process can be burdensome in stereo vision applications on mobile platforms. This paper presents an approach ...

Introduction: Dental caries is the most common chronic condition in children. Recently, there has been a growing tendency to using digital panoramic radiography among clinicians. The present study aimed to determine the accuracy of digital panoramic radiography with and without software enhancement in the diagnosis of proximal dental caries in primary molars. Methods: This study was conducted u...
