Video stabilization using neural networks
Предложен алгоритм стабилизации видеопоследовательностей на основе нейронной сети, для обучения которой используются только предшествующие кадры. В качестве кодера выступает адаптированная сеть ResNet-50. Показано, что предложенный алгоритм немного уступает алгоритму подпространственной стабилизации, что компенсируются возможностью его использования в режиме реального времени.A video stabilization algorithm based on a neural network is proposed, for the training of which only previous frames are used. The ResNet-50 network has been adapted as a conference code. It is shown that the proposed algorithm is slightly inferior to the subspace video stabilization algorithm, which allows it to be used in real time

Twisted Few-Mode Optical Fiber with Improved Height of Quasi-Step Refractive Index Profile
This work presents designed and fabricated silica few-mode optical fiber (FMF) with induced twisting 10 and 66 revolutions per meter, core diameter 11 µm, typical “telecommunication” cladding diameter 125 µm, improved height of quasi-step refractive index profile and numerical aperture 0.22. Proposed FMF supports 4 guided modes over “C”-band. We discussed selection of specified optical fiber parameters to provide desired limited mode number over mentioned wavelength range. Some results of tests, performed with pilot samples of manufactured FMF, are represented, including experimentally measured spectral responses of laser-excited optical signals, that comprise researches and analysis of few-mode effects, occurring after fiber Bragg grating writing
