Abstract:
Many animals are able to perceive stereoscopic depth owing to the disparity information that arises from the left and right eyes' horizontal displacement on the head. The initial computation of disparity happens in primary visual cortex (V1) and is largely considered to be a correlation-based computation. In other words, the computational role of V1 as it pertains to stereoscopic vision can be seen to roughly perform a binocular cross-correlation between the images of the left and right eyes. This view is based on the unique success of a correlation-based model of disparity-selective cells { t

Abstract:
Minimally invasive surgery has been a major advance in the practice of medicine as it reduces the morbidity associated with larger incisions required for open surgery. A videoscopic system is used to capture and transmit two-dimensional images of the patient during a procedure. In open surgery, the binocular configuration of the human visual system is used to generate key depth information. Minimally invasive surgery requires interpretation of monocular visual cues to perform visuospatial judgments and complex psychomotor skills. The absence of binocular depth cues extends the learning curve d

Medical imaging is a generic term used to define the use of medical practices to create images of the human body for clinical purpose. Today it includes a wide range of different techniques and these have greatly enhanced the quantity and quality of information available in the clinical practice. The clinician may now obtain a comprehensive view of internal structures of the human body, such as heart, kidney, lung, gut and so on. Computer assistance plays a relevant role in all these clinical applications. Each imaging technique is indeed associated with some kind of specialized workstation wh

Abstract:
Although stereoscopic depth perception has been a common subject of research since 1838, it is only recently that a fundamental division between two types of stereoscopic processing -- first-order and second-order -- has been identified. The precise functioning of the neural mechanisms that underlie these processing streams, however, is not yet understood. It was first confirmed that first-order stereopsis mechanisms are best investigated with vertically oriented stimuli at small disparities , whereas second-order stereopsis mechanisms prefer stimuli at large disparities.

Abstract:
It is commonly known that stereopsis is the primary way for humans to perceive depth. Although, with one eye, we can still interact very well with our environment and do very highly skillful tasks by using other visual cues such as occlusion and motion, the resultant e ect of the absence of stereopsis is that the relative depth information between objects is essentially lost (Frisby,1979). While humans fuse the images seen by the left and right eyes in a seemingly easy way, the major problem - the correspondence of features - that needs to be solved in all binocular stereo systems of mac

Abstract:
Stereoscopic vision is a technique for calculating the depths of objects in a scene from two images. Ultrasonic ranging is a well-established technique for estimating the distance to objects by bouncing an acoustic pulse off the object and measuring the time-of-flight. As with any types of sensors, these techniques each have their associated strengths and weaknesses. Therefore it is desirable to be able to use both sensor types simultaneously on a robot such that the benefits of the techniques can each be taken advantage of.

Abstract:
The human visual ability to perceive depth looks like a puzzle. We perceive three-dimensional spatial information quickly and efficiently by using the binocular stereopsis of our eyes and, what is mote important the learning of the most common objects which we achieved through living. Nowadays, modelling the behaviour of our brain is a fiction, that is why the huge problem of 3D perception and further, interpretation is split into a sequence of easier problems. A lot of research is involved in robot vision in order to obtain 3D information of the surrounded scene. Most of this research is base

Abstract:
Ce document traite de plusieurs aspects de la vision stereoscopique par ordinateur. Cette methode consiste a partir d'une ou de plusieurs paires d'images a reconstruire une scene observee en trois dimensions, c'est-a-dire a produire une description des objets et surfaces observes ainsi que leur position dans l'espace. Le premier probleme aborde est celui du calibrage, dont l'objet est de calculer les parametres des cameras (focale, centre optique, etc. ) ainsi que leur position, soit a partir d'images d'objets de geometrie et de position connue, soit de maniere automatique (on parle alors d'au

Abstract:
Nesta dissertação é apresentado o desenvolvimento de uma ferramenta computacional para o processamento de pares de imagens estereoscópicas obtidos por câmeras aéreas métricas e não métricas. O programa foi desenvolvido na linguagem C++ e foi utilizado a biblioteca OpenGL. O resultado obtido é uma imagem tridimensional de onde pode ser extraídas cotas de altura e formas de terreno. Estas imagens poderão ser usadas no estudo de áreas de risco em encostas.<br>In this dissertation is presented the development of a computational tool for the processing of pairs of images estereoscópicas obtained by

Abstract:
This master’s thesis deals with the fundamentals of machine vision application and its practical implementation. The research part is focused on the basic possibilities of image acquisition and image processing in different dimensions. The practical part describes the design of the dimension control algorithm using a 3D camera. This algorithm is then implemented in a single-purpose machine for optical dimension control.

Abstract:
O desenvolvimento da realidade virtual permitiu experimentos psicofísicos inéditos, como o aqui descrito, cujo objetivo foi investigar a microgênese da percepção visual de profundidade decorrente de disparidade binocular. Tais processos ocorrem em etapas, com construção gradual do percepto. Experimentos já indicavam a percepção da profundidade em etapas precoces do processamento visual. Isso é confirmado neste trabalho, realizado com tecnologia que garante a estimulação visual exclusivamente por disparidade binocular. Para isso, foram desenvolvidos hardware e software específicos que permitem
