Recgnition rate of traditional face recognition algorithm would decline sharply under the condition of variance Gaussian noise. In order to deal with this problem, an algorithm of Pulse Coupled Neural Network (PCNN) combined with linear discriminant analysis (LDA) is put forward. The experiment results of the algorithm are analyzed and compared with that of Median Filter(MF) combined with LDA.
The distributed caching management enabled wireless networking technology can greatly improve the data storage and transmission efficiency of wireless users and correspondingly the users' quality of experience (QoE). How to alleviate the pressure on network access while ensuring the content consistency is still a challenge. In this paper, we investigate the vehicular users oriented caching management...
Impulse radio ultra-wideband (IR-UWB) technology offers an accurate ranging ability by exploiting the time of arrival (TOA) information of the narrow pulse. However, capturing this sub-nanosecond (ns) width pulse in dense multipath environment requires expensive and power-hungry high performance analog-to-digital converters (ADCs) and complex digital signal processing. To reduce the complexity, a...
The traditional Finite Element Method (FEM) and Statistical Energy Analysis (SEA) are widely used in predicting structure noise of vehicles. However, these two kinds of methods both have defects in solving the Mid-Frequency problems. In this work, a hybrid FE-SEA vehicle modal is built to analysis the structural-acoustic system over frequency range 200–500 Hz. Experiments are carried out to acquire...
