Abstract:

The visualization of volume data is a fundamental component in the medical domain. Volume data is used in the clinical work-flow to diagnose patients and is therefore of uttermost importance. The amount of data is rapidly increasing as sensors, such as computed tomography scanners, become capable of measuring more details and gathering more data over time. Unfortunately, the increasing amount of data makes it computationally challenging to interactively apply high quality methods to increase shape and depth perception. Furthermore, methods for exploring volume data has mostly been designed for

Abstract:

In two experiments the Weighted Salience Model (WSM) of conceptual combination was examined. Several of the hypotheses set forth in the WSM were evaluated, including the importance of salience of constituent features, differential interpretation strategies based on similarity, an initial reliance on the modifier as opposed to the head, and a context effect of salience reorganization. Results confirmed that the hierarchy of output dominance within constituent features was important in determining features in final combinations. Additionally, similar pairs were defined with property interpreta

Abstract:

Grand Prix cars are the fastest circuit racing cars in production, a large part of this is due to the high downforce generated by the car's aerodynamic surfaces, in excess of the car's own weight above 150kph. It is well known that a race-car operating in the wake of an upstream vehicle experiences a reduction of aerodynamic drag, and a corresponding increase of ultimate straight line speed. There is also a loss of aerodynamic downforce, predominately from surfaces acting on the front axle. The effect of the reduced downforce is an increase of lap-time and degraded handling characteristics, th

The shortage of water as a resource is a threat to which both Ethiopia and England are exposed.

The central concern of this thesis is to discuss interpretations of learning in educational research. A point of departure is taken in core epistemological and ontological assumptions informing three major approaches to learning: behaviourism, cognitive constructivism and socioculturalism. It is argued that all three perspectives provide important insights into research on learning, but each alone runs the risk of reducing learning and interpretations of learning to single aspects. Specific attention is therefore given to Intentional Analysis, as it has been developed to account for sociocultu

Visual Attention is an interesting concept that constantly widens its application areas in the field of image processing and computer vision. The main idea of visual attention is to find the locations on the image that are visually attractive. In this thesis, the visually attractive regions are extracted and tracked in video sequences coming from the vision systems of mobile platforms. First, the salient regions are extracted in each frame and a feature vector is constructed for each one. Then Scale Invariant Feature Transform (SIFT) is applied only to the salient regions to extract more stabl

Moreover, in some application it’s important to guarantee that the model will never run out of cost budget given any testing instance, e.g. real-time application with limited response time. Researchers have tried to model the trade-off between performance and cost, but they often assume that the costs

Abstract:

碩士<br>國立勤益科技大學<br>電子工程系<br>105<br>In this paper, we proposed a feature preserving polygonal mesh simplification method based on vertex salience. Our approach adopted a simple and effective vertex salience estimation to capture the features and a linear-time algorithm based on our earlier works. Compared with existing works, our novel approach not only has better run-time efficiency at generating level-of-detail meshes but also is capable of preserving visually important details.

Abstract:

碩士<br>國立交通大學<br>電控工程研究所<br>104<br>Image segmentation is an essential and challenging problem in computer vision and image processing. Foreground extraction is one of image segmentation that separates an image into two regions, which are foreground and background. The definition of the foreground is the portion of a scene nearest to the viewer and a prominent position within the image. It can be used in object detection and object recognition. Recently, a lot of methods have been proposed for foreground extraction. However, the procedures of those methods need some interactions of users. It mak

Abstract:

碩士<br>國立臺灣大學<br>資訊工程學研究所<br>103<br>There are a few existing annotation systems that aim to provide a platform for video annotation. Most of them focus on activity annotation while others concentrate on labeling individual objects. However, the latters focus on only labeling objects with bounding boxes or only using interpolation techniques to help user labeling. Moreover, only one of them try to find the dense correspondence inside the object contour. Issues of dense correspondences annotation across video frames are not well addressed yet. Inspired by this, a video annotation system that focu

Abstract:

As an emerging technology, hyperspectral imaging provides huge opportunities in both remote sensing and computer vision. The advantage of hyperspectral imaging comes from the high resolution and wide range in the electromagnetic spectral domain which reflects the intrinsic properties of object materials. By combining spatial and spectral information, it is possible to extract more comprehensive and discriminative representation for objects of interest than traditional methods, thus facilitating the basic pattern recognition tasks, such as object detectio

Abstract:

博士<br>國立中正大學<br>資訊工程研究所<br>104<br>Scene text detectors usually consist of preprocessing, feature collection, candidate text block generation units, and text block detection. In this dissertation, we propose a robust text detector with the four new proposed units for detecting text strings in scene images. In preprocessing, both resizing and low-complexity are first used for easily predefining a general range of text sizes and coarsely reducing interference of background to make a striking effect on performance. Second, we propose three novel methods of saliency feature extraction (SFE), simple
