Abstract:
Encoding the shape of objects within the visual environment is one of the important roles of the visual system. This thesis investigates the proposition that human sensitivity to a broad range of closed-contour shapes is underpinned by multiple shape channels (Loffler, Wilson, & Wilkinson, 2003). Radial frequency (RF) contours are a novel type of stimulus that can be used to represent simple and complex shapes; they are created by sinusoidally modulating the radius of a circle, where the number of cycles of modulation defines the RF number (Wilkinson, Wilson, & Habak, 1998).

Abstract:
This thesis explores the challenge of automatic music transcription with a combination of digital signal processing and machine learning methods. Automatic music transcription is important for musicians who can't do it themselves or find it tedious. We start with an existing model, designed by Sigtia, Benetos and Dixon, and develop it in a number of original ways. We find that by using convolutional neural networks with filter shapes more tailored for spectrogram data, we see better and faster transcription results when evaluating the new model on a dataset of classical piano music.

Abstract:
Shadows in indoor scenarios are usually characterized with multiple light sources that produce complex shadow patterns of a single object. Without removing shadow, the foreground object tends to be erroneously segmented. The inconsistent hue and intensity of shadows make automatic removal a challenging task. In this thesis, a dynamic thresholding and transfer learning-based method for removing shadows is proposed. The method suppresses light shadows with a dynamically computed threshold and removes dark shadows using an online learning strategy that is built upon a base classifier trained with

Intellectual stimulation of young children is crucial, because it helps to break the cycle of poverty by giving each child the skills needed to reach his or her maximum potential. There is a growing need for more extensive early childhood development programmes in South Africa. Several studies in early childhood development have been shown to directly draw a parallel with enhanced student achievement at school and in life (Ackerman, 2005; Bueno, Darling-Hammond, & Gonzales 2010; Frede, Jung, Barnett, & Figueras, 2009). This study therefore explored the effects of an intervention programme i

Abstract:
Modern organizations increasingly rely on teams to act as information processors—pooling and integrating various sources of information in order to solve complex problems and reach quality decisions. Traditional frameworks for the influence of diversity suggest that diversity can enhance decision making by adding to the backgrounds and perspectives that can be applied to a given task. However, this additive view of diversity is unable to account for more recent findings that show that members of homogeneous and diverse groups differ in their decision-making processes even when they have access

Abstract:
隨著互聯網上3D模型的大量增加，產生了開發3D模型搜索引擎的需求。本論文提出了一個基於草圖和3D模型的3D模型搜索引擎。<br>對於使用3D模型作檢索條件的搜索系統，我們提出了兩種新的3D模型描述子，分別叫做Sphere Image 描述子和Bag-of-View-Words (BoVW)描述子。Sphere Image描述子是由一系列投影圖的特徵組成。我們將每一個視角看到的圖形都當作是一個"像素"，把視角的位置看作像素點的位置，把所看到的圖形的特徵值看作是像素值。我們同時也提出了一種基於概率圖的3D模型匹配算法，並開發了一個3D模型檢索系統來檢測我們的算法。BoVW描述子通過3D模型投影圖出現的次數來描述3D模型。我們用一種自適應的聚類算法，對3D模型的所有投影圖進行分類，然後用一個多層次的柱狀圖來描述一個3D模型。我們同時提出一種新的金字塔匹配算法來比較3D模型。我們使用SHREC和普林斯頓的3D模型庫來檢驗我們的系統，實驗結果證明我們的系統在檢索效率和精度上都優與現今的3D模型檢索系統。<br>對於使用草圖作檢索條件的3D模型搜索系統，我們提出Bigger ExposureOpportunity Views (BEOV) 描述子來表示3D模型，同時提出Shape-Ring描述子來表示草圖。BEOV描述子是由一些特徵圖組成，這些圖的特點是更容易被人們看到。Shape-Ring描

Abstract:
Moving object detection is a first step towards many computer vision applications, such as human interaction and tracking, video surveillance, and traffic monitoring systems. Accurate estimation of the target object’s size and shape is often required before higher-level tasks (e.g., object tracking or recog nition) can be performed. However, these properties can be derived only when the foreground object is detected precisely. Background subtraction is a common technique to extract foreground objects from image sequences. The purpose of background subtraction is to detect changes in pixel values

Abstract:
High power diode laser is potentially attractive in several manufacturing domains. Transfer efficiency by far higher than competitors, long lasting source, easy setting-up and automation, lack of maintenance as well as moderate investment and running costs make diode laser extremely promising in forming process. Available technologies are numerous, but laser forming has the advantages of limited springback, lack of molds and sophisticated auxiliary equipment. Nevertheless, the achievement of complex shape with high dimensional accuracy and precision by forming with diode laser is still poorly
