Road vehicle classification plays an important role in traffic surveillance, traffic security, and transportation management systems. This paper proposes a novel vehicle classification algorithm based on extreme learning machine. Invariant moments and horizontal edge features are extracted to classify...

This paper put forward a method for speaker recognition and speech emotion recognition based on GMM. The reason of using this model is its ability to the dependency among extracted speech signal feature vectors and the multi-modality in their distribution. Firstly, we extracted the Mel Frequency Cepstral...

The key of local matching algorithm is the selection of similarity measure function and window’s size, this paper through the two aspects to do improvement. Due to the traditional adaptive window algorithm is relatively complex, this paper extracted a relatively simple adaptive window algorithm, that...

When images compressed by traditional transformation-based compression algorithms are transmitted over wireless channels, if the gaussian random interference causes the loss of the crucial transformation coefficients, the contents of the reconstructed images will be lost obviously and this will reduce...

This article aim at the application of the high real-time required embedded terminal situation, an improved SIFT algorithm is proposed. After traditional SFIT algorithm get the stable points, global texture description was carried out on the key points of frequency domain by contourlet transform, select...

The new introduced concept, transform tree or residual quadtree (RQT) in HEVC standard, brings high coding performance along with high computational complexity because the optimal TU partition is estimated in a rate-distortion sense at the encoder sides by testing all kinds of partitions. This paper...

Fly detection method using for airborne pulse Doppler phased array early warning radar detection range performance evaluation is complex, expensive and time-consuming task. In order to comprehensively evaluate the radar detection performance, it needs many data statistic independently. Inspection fly...

Traditional GNSS receiver usually uses Least Squares (LS) method or Kalman filtering to calculate the position. This paper proposes a new method that uses particle filtering for positioning calculation. The proposed particle filtering bases on LS method, but resolves the low positioning accuracy problem...

DVB-T standard has been one of the most important standards for terrestrial transmission in the world. According to investigate the principle of DVB-T baseband system, this paper focus on the key module of DVB-T modulator and synchronous module. Firstly, this paper establishes a complete DVB-T transmitter...

A digital method of noise measurement of charge-sensitive preamplifiers (CSP) used with detectors of ionizing radiation has been proposed, which benefits from the fast development of digital techniques. Compared with the classical methods recommended by IEEE Std 301-1988, CEI/IEC 61151 and GB/T 4079-94,...

For realizing the network and information of high-end printing machines, the remote fault monitoring system based on Apache, MySQL and PHP under the Windows system (WAMP) for network environment is presented. The open source environment of WAMP is used in this system, which can easily set up a remote...

Aimed at the problem that PSD output position is not the laser spot center coordinate formed on PSD in the measurement of transient angle, factors affecting the accuracy of testing system is analysed in this paper. from the work principle of PSD and detection experiment, the energy distribution and light...

The image reconstruction for electrical capacitance tomography (ECT) is a nonlinear, underdetermined and ill-posed inverse problem. It is difficult to achieve a reconstructed image with higher quality, especially in 3D reconstruction. The study of image reconstruction algorithm is a crucial issue in...

This manuscript present the operation and construction of a glove that help deaf-mute communication by identifying the position of the fingers of the hand to translate the letters into words and send audio signals. Also we present an improve in the translator glove by adding a portable voice synthesizer...

Moving target detection is an important content of the visual field of research,This paper designs a system based on the Linux embedded platform to realize the moving target detection and tracking. This system choose the optical flow method as the algorithm, which is one of the important algorithms in...
