We present the experimental investigation of formation and growth of Ag nanocrystals in silica photo-thermo-refractive glasses under the electron-beam irradiation and subsequent thermal treatment. The influence of electron irradiation fluence, current density and thermal treatment conditions on nanocrystal growth dynamic has been investigated. Theoretical models and computer simulation of main processes which take place during electron-beam irradiation are presented. 相似文献

The present paper deals with the algorithms of image processing using CUDA technology. Memory optimizations are the most important
area for performance of a CUDA application. This is especially urgent for the recurrent algorithms of data processing. The
paper proposes a new approach for recurrent data processing on the GPU. The effectiveness of this approach is shown for the
moving average algorithm. The proposed algorithms were used to develop image processing software system. Some results obtained
for this system are given in the paper. 相似文献

In this paper, the problem of false operation of a detector of abandoned objects in video surveillance systems during the
appearance of sun flares is examined. Two algorithms of flare recognition are presented in this paper. The main feature of
the algorithms is the possibility to analyze the shape of detected flares in order to raise the quality of the recognition.
The first algorithm is based on application of the active contour technique with analysis of geometric characteristics. This
algorithm is compared with the author’s technique, which uses nested windows and analysis of the fractal dimension. After
the comparison of the performance and precision of algorithms, a decision about use of one of the algorithms in real-time
video surveillance systems will be proposed. 相似文献
