Laser cleaning is a non-contact  green and environmental cleaning method  which can effectively remove particulate contaminations of sizes as small as 0.1 m without damage to the optics. But most laser cleaning devices are large and heavy  also expensive due to using large lasers such as CO2 laser  YAG Laser etc. In this work a low power LD was tried to clean fingerprint and dust contaminated on the surface of the attenuator glasses plates. In the laser cleaning experiment with low power diode the fingerprint grease can be efficient to be cleaned  but there is no evident effect for cleaning inorganic dust. The cleaning different degree of fingerprint contaminations was investigated at the variable laser parameters  including laser power and irradiation time. An optical microscope was used to analyze the cleaning effect. The results show that low power LD can effectively remove the fingerprint on the surface of absorptive-type attenuator glass plates. On the premise that the attenuator optics glasses are not damaged  the cleaning area increases with the increase of radiation time and laser power. The cleaning area doesn't change much with the variation of laser frequency when the other parameters are the same. (2013) Trans Tech Publications  Switzerland.

In this paper we present a new method for automatically visual recognition and semantic segmentation of photographs. Our automatically and rapidly approach based on Cellular Automation. Most of the analysis and description of recognition and segmentation are based on statistical or structural properties of this attribute  most of them need plenty of samples and prior Knowledge. In this paper  within a few evident samples (not too many)  we can first get the texture feature of each component and the structures  then select the approximately location randomly of the objects or patches of them  then we use the Cellular Automata algorithm to "grow" based on texture of different objects. The grow progress will stop When texture grow to the boundary. By this steps a new method is found which allow us use very few samples and low lever experience and get a rapidly and accuracy way to recognize and segment objects. We found that this new propose gives competitive results with limited experience and samples. 2011 IEEE.

A new particle filter-the Local Optimum Particle Filter (LOPF) algorithm is presented for tracking object accurately and steadily in visual sequences in real time which is a challenge task in computer vision field. In order to using the particles efficiently  we first use Sobel algorithm to extract the profile of the object. Then  we employ a new Local Optimum algorithm to auto-initialize some certain number of particles from these edge points as centre of the particles. The main advantage we do this in stead of selecting particles randomly in conventional particle filter is that we can pay more attentions on these more important optimum candidates and reduce the unnecessary calculation on those negligible ones  in addition we can overcome the conventional degeneracy phenomenon in a way and decrease the computational costs. Otherwise  the threshold is a key factor that affecting the results very much. So here we adapt an adaptive threshold choosing method to get the optimal Sobel result. The dissimilarities between the target model and the target candidates are expressed by a metric derived from the Bhattacharyya coefficient. Here  we use both the counter cue to select the particles and the color cur to describe the targets as the mixture target model. The effectiveness of our scheme is demonstrated by real visual tracking experiments. Results from simulations and experiments with real video data show the improved performance of the proposed algorithm when compared with that of the standard particle filter. The superior performance is evident when the target encountering the occlusion in real video where the standard particle filter usually fails.

The threshold voltage of a-Si: H/SiNx TFT will shift under long time gate bias stress  it is mostly leaded by charge trapping in gate insulator and defect creation in semiconductor. And it is hard to be applied in AMOLED for TFT because of its threshold voltage shift. In allusion to the phenomenon of charge trapping  a series of SiNx insulating films in different N/Si(0. 87 -1.68) ratio were deposited by PECVD in this paper  controlling different flow ratio of source gas SiH4 and NH3  and a great deal of tests (ellipsometer  infrared absorption (FTIR) and Electron Dispersion Spectrum (EDS) test ) were done on these samples. Based on these SiNx insulators  three different capacitance samples in MIS structure were done  degraded experiments and C-V tests on these samples were done. The C-V curve shift of capacitance which contained SiNx with slightly N-rich(N/Si is bigger slightly than 1. 33) was not evident before and after degradation  this result indicated that the defect density of this type SiN x was smaller  and could restrain charge chapping in the interface of a-Si:H/SiNx effectively. So that as gate insulator of TFT  SiN x with slightly N-rich could decrease the threshold voltage shift of TFT and enhance its stability effectively.
