Breast cancer is the most common cancer among women in Canada. Despite slight declines in mortality rates over the past decade for women with breast cancer, one in nine Canadian women will develop breast cancer in her lifetime; one in 25 Canadian women will die from this disease. Digital mammograms (X-rays of the breast) may allow better cancer diagnosis(More)
In order to utilize peer-to-peer (P2P) networks in legal content distribution to benefit the legal content providers, copyright protection needs to be enhanced. In this paper, a fingerprint generation and embedding method is proposed for complex P2P file sharing networks. In this method, wavelet and principal component analysis (PCA) techniques are used for(More)
Analysis of nonstationary signals, such as music signals, is a challenging task. The purpose of this study is to explore an efficient and powerful technique to analyze and classify music signals in higher frequency range (44.1 kHz). The pursuit methods are good tools for this purpose, but they aimed at representing the signals rather than classifying them(More)
Application of grammar-based codes for lossless compression of digital mammograms" (2006). Abstract. A newly developed grammar-based lossless source coding theory and its implementation was proposed in 1999 and 2000, respectively, by Yang and Kieffer. The code first transforms the original data sequence into an irreducible context-free grammar, which is(More)
