In this paper, we propose a novel study for gesture identification using surface electromyography (sEMG) signal, and the raw sEMG signal and the sEMG envelope signal are collected by the sensor at the same time. An efficient method of gesture identification based on the combination of two signals using supervised learning and univariate feature selection is implemented. In previous research techniques,...
This paper proposes a new image scrambling algorithm based on the periodic characteristics of the Josephus ring. The algorithm composes the pretreatment part of the entire image encryption system and scrambles the rows and columns of the plain image. The Josephus scrambling algorithm is adjustable by using three kinds of parameters: step, m0, and n. Different values affect the size of the periodic...
In the past, investigators tend to use multi-channel surface electromyography (sEMG) signal acquisition devices to improve the recognition accuracy for the study of gesture recognition systems based on sEMG. The disadvantages of the method are the increased complexity and the problems such as signal crosstalk. This paper explores a gesture recognition method based on a single-channel sEMG envelope...
This paper introduced the characteristics of the species, lung of the lung sounds signal, acquisition, processing and identification technology, based on the computer's lung sound signal processing and pattern recognition technology, and the research status at home and abroad and a variety of approaches to the study of the lung sound signals are summarized and reviewed in this paper, through a variety...
This paper illustrates a method to recognize nonspecific two-word Chinese vocabulary by analyzing speech signals using a narrow-band spectrogram after Fourier transform is applied to it twice. Binary width zoning line projection is carried out in the frequency domain. The projection value is treated as the characteristic value of semantic recognition feature and the support vector machine (SVM) is...
This paper presents a recognition method to two words Chinese lexical for non-specific people using feature fusion of broadband and narrow-band spectrogram. In the process of image feature extraction, the image processing technique is applicable to the speech recognition field. First, equal width zoning line projection and binary width zoning line projection is carried out in the narrow-band spectrogram,...
