Perda de audição é a incapacidade parcial ou total de ouvir que afeta aproximadamente 10% da população mundial. Uma das principais consequências desta condição é a perda da capacidade do indivíduo para se comunicar com outras pessoas através da ...

This dissertation addresses the problem of reconstruction of the 3D structure of colon segments and the 3D motion of an endoscope from colonoscopy images. Colonoscopy is currently the preferred screening modality for early colorectal cancer (CRC) ...

O principal objetivo deste trabalho consistiu em desenvolver um sistema capaz de realizar a reconstrução 3D de modelos ósseos a partir de imagens radiográficas. Este sistema pode posteriormente ser integrado num produto comercial que realiza o ...

Computer facial modeling and animation has been an interest of computer graphics researchers for many years. This is not only because the face itself is an interesting object, but also because facial animation finds application in many other disciplines ...

We develop a new method that allows for more accurate biovolume calculations of microorganisms. This method also allows the volume of individual skeletal features of microorganisms to be analyzed separately so that estimates of the resource cost ...

Vision sensors mounted on mobile robotic platforms hold great promise in automated agriculture management. However, established computer vision techniques often fail to perform well in agricultural environments due to the environmental complexity, ...

Moving through a stable, three-dimensional world is a hallmark of our motor and perceptual experience. This stability is constantly being challenged by movements of the eyes and head, inducing retinal blur and retino-spatial misalignments for ...

We immerse ourselves in a wonderful world that is three-dimensional. However, dimensionality is reduced from 3D to 2D, when we visually capture the world with the ubiquitous cameras. The loss of this single dimensionality restricts the perspective ...

Biometrics axe unique to each individual and are therefore valuable for identification purposes. One of such biometrics is the individual's face; consequently the existence of the research field of face recognition. Although face recognition ...

Automatic face recognition has been an active research area for the last four decades. This thesis explores innovative bio-inspired concepts aimed at improved face recognition using surface normals. New directions in salient data representation ...

Synthesizing a 3D human face surface and texture from a drawing is a challenging problem. The problem involves inferring a 3D model and its color information from 2D information. In contrast, human beings have the natural ability to reconstruct 3D ...

Humans have the uncanny ability to perceive the world in three dimensions (3D), otherwise known as depth perception. The amazing thing about this ability to determine distances is that it depends only on a simple two-dimensional (2D) image in the ...

Unmanned Aircraft System (UAS) is a fast-growing industry with extensive economic implications and would be integrated into the national airspace system (NAS), which requires UAS to have the efficient sense and avoidance capability. This thesis ...

This dissertation mainly focused on the multidisciplinary applications of a 3D finite-difference based electromagnetic modeling which included applications in oil & gas industry as well as medical industry.For applications in oil & gas industry, ...

3D printing is a technology that employs computer-aided designs to build objects on a platform through layer-by-layer deposition. In the past decades, 3D printing has been increasingly applied in a wide array of applications related to ...

Multi-parametric magnetic resonance imaging (mpMRI) of localized prostate cancer has the potential to support detection, staging and localization of tumors, as well as selection, delivery and monitoring of treatments. Delineating prostate cancer ...

Current feature research takes two main approaches to feature model generation: feature recognition and feature based design. Feature recognition extracts features from a solid model. The feature based design approach allows designers to use directly a ...

We study the problem of 3D hand shape and pose estimation from monocular RGB images. Recent studies have shown that single-view 3D hand pose estimation is challenging due to depth ambiguity, environmental conditions, object-occlusion, and self-...

Vision-based hand tracking has been an active field of research since the early 1990s. Early attempts tended to use generative kinematic models, in which a hand state proposal is quantitatively evaluated according to features extracted from an ...
