Using terahertz time domain spectroscopy (THz-TDS), the photoresist's absorption spectrum was measured in this paper. From the experimental data, A significant difference was found in the absorption between the exposure and unexposure photoresist. And we also discuss the requirements to sample preparation imposed by the lack of sharp spectral features in the absorption specra. The experimental results...
In an indoor robot navigation system, as wireless sensor nodes have limited memory capacity and computing power, generally it is impossible to store routing information or overall geographic information in the nodes. This design adopted Bloom filter to compress route information so that large amount of data path information can be stored in a distributed way in the wireless sensor notes. This study...
In this paper, a new criterion based on image segmentation on face recognition is applied to network certification. Firstly, the original images are divided into modular images, which are also called sub-images. Then, the well-known Fisher linear discriminant analysis is directly employed to the sub-images obtained from the previous step. Finally the recognition results are obtained by the general...
In this paper, based on face recognition, the core algorithm is studied, which was applied in access control system. This algorithm carries on two-dimensional principal component analysis (2DPCA), singular value decomposition (SVD) and the fusion of 2DPCA and SVD, which the main characteristic vector of the PCA is fused to form a new one that is taken as the distinction standard. The experiment results,...
Nowadays the network information security is an important research direction on data communications. In order to solve a number of shortcomings in information security password system, in this paper, a new criterion based on image segmentation on face recognition is applied to network security. Firstly, in proposed approach, the original images are divided into modular images, which are also called...
In the paper, phase correlation algorithm based on FFT is applied to the vehicle license plate character identification of the intelligent transportation systems. It is a widely used method of image registration, which can not only increase the speed of the license plate character recognition and the generalization ability of system, but also accurately identify some similar characters or obscured...
In this paper, based on face recognition, the core algorithm is studied, which was applied in access control system of logistics management industry. This algorithm carries on the SVD and 2DPCA transformation in the face image, which the main characteristic vector of the PCA is fused to form a new one that is taken as the distinction standard. By means of ORL and Yale face database. The recognition...

In this paper, some of face recognition algorithms are compared, which are based on Two-dimensional principal component analysis (2DPCA), singular value decomposition (SVD) and the fusion of 2DPCA and SVD. The experiment results, by means of ORL and Yale face database, indicate that the algorithm combined 2DPCA and SVD-U has a higher recognition rate, 87% and 95.9%, respectively. And it can have better...
In this paper, the core algorithm is studied, which aiming at developing a robust and practical entrance guard & check on work attendance system based on face recognition, and this system is applied to the logistics management industry. Firstly, this algorithm divides the image into block images, which are also called sub-images. Then the well-known Fisher method is directly employed to the selecting...
