Nowadays, the advance in sensors network, integrated circuit and wireless communication technologies giving capability of designing lightweight and low-cost sensor nodes particularly for healthcare application. In this paper, a wearable belt-type ECG electrode worn around the chest is designed for sake of the convenience to measure real-time ECG. The measured ECG signals carry a lot of clinical information...
Proper alignment of singing voice to its corresponding musical score is particularly important for singing voice analysis and processing in many applications. This paper proposes a method to align singing voice with its MIDI melody. The MIDI is first converted into a synthesized music audio file. Then spectral features are calculated for both singing voice and MIDI synthesis files. Next dynamic time...
It accords with the human's intelligence for data processing that we do information granulation of time series and then study and analyze the time series on the different level of granularities. There are two kinds of traditional methods for the information granulation of temporal data. One implements the granulation by first dividing the time series into segments in terms of the granularity of the...
This paper describes a new analysis method dedicated to the comparison of human gestures. The orientations and the positions of the gestures are first digitized using active 3D sensors and then compared to a 6-D template using curvature analysis. The proposed algorithm first starts by computing the invariant curvature of 3D position and orientation of a surgical tool using Frenet-Serret frames in...
This work describes an enhanced technique for on-line signature verification. The distance between two signatures is computed by dynamic time warping (DTW) method. The reference signatures are used to assign special parameters for each signer, which makes the system cover the intra signer variation. Several features are extracted. Systems with single and multi-features are tested. Curvature change...
Online shopping is becoming more and more popular for a number of reasons; prices are often lower online, you don't have to queue up in busy shops and you can buy almost any product imaginable with just a few clicks of your mouse. But the general problems of shopping Web site is that, most of the existing online shops list products based on keywords. As the inherent limitation, keyword browsing makes...
Time series data has been rapidly aggregated in many domains, such as meteorology, astrophysics, geology, multimedia, and economics. Similarity search is a core module of the tasks of time series data mining, such as classification and clustering. Dynamic time warping (DTW) is a robust distance measure method for time series data, minimizing the effects of shifting and distortion in time. Unfortunately,...
The aim of this paper is to classify the vibroarthrographic (VAG) signals according to the pathological condition using the characteristic parameters extracted by the time-frequency transform, and to evaluate the classification accuracy. VAG and knee angle signals, recorded simultaneously during one flexion and one extension of the knee, were segmented and normalized at 0.5 Hz by the dynamic time...
The identification of chromosome abnormalities is an essential part of diagnosis and treatment of genetic disorders such as chromosomal syndromes and many types of cancer. Modern cytogenetic imaging techniques have improved the study of chromosome aberrations but they are most often used as adjuncts to traditional G-banded karyotype analysis. Molecular cytogenetic techniques such as comparative genomic...
