Résumé :

Audio analysis algorithms and frameworks for Music Information Retrieval (MIR) are expanding rapidly, providing new ways to discover non-trivial information from audio sources, beyond that which can be ascertained from unreliable metadata such as ID3 tags. MIR is a broad field and many aspects of the algorithms and analysis components that are used are more accurate given a larger dataset for analysis, and often require extensive computational resources. This thesis investigates if, through the use of modern distributed computing techniques, it is possible to design an MIR system that is scala

Résumé :

Research in the field of music information retrieval (MIR) is concerned with methods to effectively retrieve a piece of music based on a user's query. An important goal in MIR research is the ability to successfully retrieve music stored as recorded audio using note-based queries. In this work, we consider the searching of musical audio using symbolic queries. We first examined the effectiveness of using a relative pitch approach to represent queries and pieces. Our experimental results revealed that this technique, while effective, is optimal when the whole tune is used as a query. We th

Résumé :

The overwhelming availability of large multimedia collections poses increasingly challenging research problems regarding the organization of, and access to data. A general consensus has been reached in the Information Retrieval community, asserting the need for tools that move past metadata-based techniques and exploit directly the information contained in the media. At the same time, interaction with content has evolved beyond the traditional passive enjoyment paradigm, bringing forth the demand for advanced control and manipulation options.

Résumé :

Automatic music genre classi cation is a high-level task in the eld of Music Information Retrieval (MIR). It refers to the process of automatically assigning genre labels to music for various tasks, including, but not limited to categorization, organization and browsing. This is a topic which has seen an increase in interest recently as one of the cornerstones of MIR. However, due to the subjective and ambiguous nature of music, traditional single-label classi cation is inadequate. In this thesis, we study multi-label music genre classi cation from perceptual and computational perspectives. F

Résumé :

The computer classification of musical audio can form the basis for systems that allow new ways of interacting with digital music collections. Existing music classification systems suffer, however, from inaccuracy as well as poor scalability. Feature selection is a machine-learning tool that can potentially improve both accuracy and scalability of classification. Unfortunately, there is no consensus on which feature selection algorithms are most appropriate or on how to evaluate the effectiveness of feature selection.

The Cognition of Atonal Pitch Structures investigated the ability of a listener to internally organize atonal pitch sequences into hierarchical structures. Based on an information processing model proposed by Deutsch and Feroe (1981), the internal organization of well processed pitch sequences will result in the formation of hierarchical structures. The more efficiently information is processed by the listener, the more organized its internal hierarchical representation in memory.

For this, a novel conceptual and mathematical framework named “Music Interpretation Analysis” (MIA) is presented. In the proposed framework, a distinction is made between the “performance” – the physical action of playing – and the “interpretation” – the action that

This thesis addresses the problem of named entity recognition (NER) in music-related search queries. NER is the task of identifying keywords in text and classifying them into predefined categories.

This task is, however, acknowledged to be challenging due to queries being short, ungrammatical and containing minimal linguistic context.

Machine categorisation of the emotional content of music is an ongoing research area.

In this thesis, we address the problems of classifying and recommending music present in large collections.

To this end, we first focus on the problem of linking music-related texts with online knowledge repositories and on the automated construction of music knowledge bases. Then, we show how modeling semantic information may impact musicological studies and helps to outperform purely text-bas

Résumé :

Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage a

In order to increase the ability to describe the information of music, we take account of three perceptual phenomenon including auditory physiology, psychoacoustic and music expectation. Furthermore, we use Bayesian statistics to automatic learning the content parameter in the model. In this way, we can begin by setting the initial probability distribution of parameter according to music theory, then fitting to proper distribution in li

Résumé :

A series of experiments investigate the roles of relational coding and expectancy in memory for melodies. The focus on memory for melodies was motivated by an argument that research on the evolutionary psychology of music cognition would be improved by further research in this area. Melody length and the use of transposition were identified in a literature review as experimental variables with the potential to shed light on the cognitive mechanisms in memory for melodies; similarly, pitch interval magnitude (PIM), melodic contour, metre, and pulse were identified as musical attributes that app

碩士<br>南台科技大學<br>多媒體與電腦娛樂科學研究所<br>94<br>Systems based on computer vision and image processing are widely developed in scientific and medical applications. On the other hand, integrated analyses of color, psychology, music, and showing ways of multimedia are useful and helpful in life entertainments. Association of the two fields becomes more and more popular in recent years, and it will be a trend in the future. This motivates us to design a creative and interactive multimedia system that can recognize and capture the color information of one’s wearing when one enters a space. After the color r
