摘要：

The last data on the search results for neutrino oscillations in the OPERA experiment and the completed modernization of the PAVICOM facility (Lebedev Physical Institute) for automatic processing of nuclear emulsions of this experiment are presented. A new test application is developed for the PAVICOM to perform all stages of image processing. The application is tested using a GTX570 video card. The processing time for one frame is significantly reduced, which made it possible tomore than tenfold speed up processing. This is of crucial importance not only for prompt acquisition of statistically significant data of the OPERA experiment, but also for planned works on muon radiography.
