In this paper, a new design of the Discrete Wavelet Packet Transform with efficient hardware acceleration is implemented. This design works based on the word serial pipeline architecture and the parallel filter processing. For accelerating in the Discrete Wavelet Packet Transform, a high-pass filter and a low-pass filter are used concurrently in each level. Using parallel filters makes possible...

Among the most significant characteristics of human beings is their ability to feel emotions. In recent years, human-machine interface (HM) research has centered on ways empower classification Mainly, human-computer interaction (HCI) concentrates methods that enable computers reveal emotional states humans. this research, an emotion detection system based visual IAPPS pictures through EMOTIV EP...

this article is for the coupling fault diagnosis of rotor system, and does in-depth analysis of the rotor unbalance and misalignment, and the fault formed by the coupling of these two. Through research, Rotor Coupling was found filled with rich features. In this paper, Wavelet packet de-noising ideas being introduced to the local Fisher discriminant analysis (LFDA), a new method of fault diagno...

In the fault diagnosis of the motor, the vibration signals can fully reflect the status of the motor. In this paper, on the basis of wavelet packet fault feature extraction, a new approach for motor fault diagnosis based on wavelet packet analysis and fuzzy RBF neural network was presented.The method gains the energy of characteristic channel of bearing failure vibration signals of asynchronous...

In this paper, we present a wavelet packet image coding algorithm based on quadtree classification and UTCQ. It is composed of four parts: (1) wavelet packet decomposition and best basis selection based on a new cost function, (2) a quadtree classification procedure, used to classify the wavelet packet coefficients into two sets: a significant one and an insignificant one, (3) the universal tre...

Wavelet transform is a powerful tool for analysing the problems arising in harmonic analysis, signal and image processing, sampling, filtering, so on. However, they seem to be inadequate representing those signals whose energy not well concentrated frequency domain. In pursuit of representations such signals, we propose novel time-frequency coined as quadratic-phase wave packet L2(R). The propo...
