Abstract:

To extract information from a scene captured in digital images where the information represents some kind of feature is an important process in image analysis. Both the speed and the accuracy for this process is very important since many of the analysis applications either require analysis of very large data sets or requires the data to be extracted in real time. Some of those applications could be 2 dimensional as well as 3 dimensional object recognition or motion detection. What this work will focus on is the extraction of salient features from scenes of buildings, using a joint histogram ba

Abstract:

Search for combinations of orientation, shape, color, direction of motion, and binocular disparity should be slower than search for any one of them in isolation. Recent results showing fast search for certain combinations of these features havef prompted theorists to suggest that features like orientation may be represented separately depending on the color, texture, or other medium that distinguishes them from the background (Cavanagh, Arguin, & Treisman, 1990; Treisman, 1988). Enns and Wig (1989) provide evidence that edge orientation is represented independently from the medium in which it

Abstract:

Soil carbon (C) and nitrogen (N) are predominantly in organic form. Proteins/ peptides, as an important organic form of N, constitute a substantial part of soil organic matter. On one hand, proteins/peptides are an important N source for plants and microorganisms, particularly in soils where inorganic N is limited. On the other hand, their stabilization in soils by forming organo-mineral associates or macromolecule complex reduces the C loss as CO2 into the atmosphere. Therefore, studies on the turnover, abundance, composition, and stability of proteins/peptides are of crucial importance to ag

Abstract:

Continental rifting is an important geodynamic process during which the Earth's outer-most rigid shell undergoes continuous stretching resulting in continental break-up and theformation of new oceanic basins. The East African Rift System, which has two continentalsegments comprising largely of the East African Rift (EAR) to the West and the easternmostsegment Madagascar, is the largest narrow rift on Earth. However, the driving mechanismsof continental rifting remain poorly understood due to a lack of numerical infrastructure tosimulate rifting, the lack of knowledge of the underlying mantle d

Abstract:

A melhor maneira de se caracterizar o comportamento mecânico pós-fissuração dos concretos reforçados com fibras (CRF) para fins estruturais é por meio de ensaios que envolvem a ruptura do material à tração direta. Devido às dificuldades de execução destes, comumente se empregam ensaios de tração indireta, com destaque para os ensaios de flexão com sistema fechado. Entretanto, fatores limitantes, como a superestimação da capacidade resistente do compósito em testes de flexão, têm incentivado o desenvolvimento de outros métodos de ensaio mais fidedignos às características do CRF. Este é o caso d

This method mainly includes two steps: (a) to obtain gradient directions and magnitudes with an edge detection pre-process, (b) tracing a boundary by fi

Abstract:

碩士<br>國立臺灣大學<br>電機工程學研究所<br>100<br>For a mobile robot, it is necessary to have the ability to move accurately and autonomously in an unknown environment. The localization, vanishing point detection, and floor region detection problem all have a close relation to this ability. If the robot is able to localize itself, it can move accurately. Besides, the robot can explore the environment autonomously and securely with knowing the vanishing points and the floor region. Vision sensors such as camera are attractive devices since they are information-rich. Compared with monocular cameras, omnidirect

Abstract:

This thesis presents a new approach to scene representation for prosthetic vision. Structurally salient information from the scene is conveyed through the prosthetic vision display. Given the low resolution and dynamic range of the display, this enables robust identification and reliable interpretation of key structural features that are missed when using standard appearance-based scene representations. Specifically, two different types of salient structure are investigated: salient edge structure, for depiction of scene shape to the user; and salient object structure, for emulation of biologi

Abstract:

Although confronting prejudice can be effective in reducing bias, it is potentially costly to confronters. Research on confronting racism or sexism has shown confronters from the targeted group are viewed more negatively than confronters who are not. It is unknown whether confronting antigay bias produces similar reactions, particularly since group membership is concealable. In my research, participants read two male profiles followed by a scripted conversation which included an antigay comment. Profiles varied in their depiction of the confronting individual’s sexual orientation, and conversa
