Local variance and single pixel value are combined to describe image structure information using complex method in this paper in order to improve the consistency of objective image assessment result with that of subjective method. The effect of the detail structure information on the image quality was emphasized by this method accordingly. Singular value decomposition was performed on local variance distribution complex matrix. The angle between the singular value vectors of the reference image and the disturbed image was used to measure their structural similarity. Then the quality assessment process was achieved. Results from experiments show that the proposed method is better consistent with human visual system characteristics than MSE PSNR and SSIM. 2012 Springer-Verlag London Limited.

We proposed a spiking neural network (SNN) to detect moving target in video streams and classify them into real categorization in this paper. The proposed SNN uses spike trains to encoding information such as the gray value of pixels or feature parameters of the target detects moving target by simulating the visual cortex for motion detection in biological system with axonal delays and classify them into different categorizations according to their distance to categorization's centers found by Hebb learning rule. The experimental results show that the proposed SNN is promising in intelligence computation and applicable in general visual surveillance system. 2012 Springer-Verlag.

This paper introduces a realtime system which can acquire process store and display heart sounds and electrocardiogram(ECG) of the human body at the same time. It is composed of superior microprocessor-Atmega128L large capacity Flash and the new type LCD. All hardwares adopt low power design and surface mounting package. The system do not affect the daily living and working of human being when it is used so it is suited for clinical and family monitoring. Springer-Verlag Berlin Heidelberg 2012.

The quality of vehicle vacuum booster with brake master cylinder is related to the safe of drivers and automobiles. The testing experiment must be executed strictly before leaving factory based on the national standards.The paper introduces the controlling system of multi-function durability testing device which is designed for doing durable testing experiments and Anti-lock braking system (ABS) performance experiments. The structure and theory of device is presented. The controlling system is illuminated in detail. To test the dynamic property this system was identified by a recursive BP neural network. According to the character of a great deal of sensors and actuators the high precision capabilities and reliability the distributed control mode (DCS) including the computer and PLC by RS-485 bus is utilized. The four channels testing experiments are achieved at the same time. The test data is directly memorized into the computer. The results of general endurance and ABS endurance testing experiments are shown to demonstrate the excellent performance of the testing device. 2012 Springer-Verlag Berlin Heidelberg.

The trend extrapolation method is applied to spectrum analysis of microtremor signal in order to increase the spectral estimation accuracy. First establish an appropriate extrapolation model based on the existing data series and then fit correlation functions other than existing data by derivative least squares method finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.

In order to minimize the size of photoelectric encoder a signal process system was designed and C8051F021 MCU was its core device. To begin with the processing electrocircuit and the data processing software used for the 16-bit encoder was developed. Then the feasibility of this system was verified by experiment. The experimental result proves that the signal process system was simple in structure and reliable. The size of the electrocircuit was 40mm.The precision of the 16-bit photoelectric encoder is 22.4". 2012 Springer-Verlag Berlin Heidelberg.

In this paper neural network predictive control method is used to compensate the image forward motion of a certain aerial reconnaissance camera and we have solved several problems that traditional control methods have. Firstly according to the principle of imaging we analyzed the reasons for the existence of image forward motion and established the mathematical model. Secondly we analyzed the theoretically feasibility of the method. At last simulation experiments and test are used to validate the practical feasibility. Through what we have done we conclude that neural network predictive control method can be used to compensate image forward motion for this certain camera and can make a perfect performance. 2011 Springer-Verlag.
