Patch-Wise Partial Face Recognition Using Convolutional Neural Network
Optical Memory and Neural Networks - Tập 31 - Trang 367-378 - 2023
Automatic face recognition still suffers from some problems in the real-world scenarios such as occlusion. Hence, identifying the face from its partial appearance is a challenging issue as yet. To address this, issue many methods have been proposed using traditional feature extraction techniques. In this paper, a partial face recognition problem has been tackled through utilizing patch-wise matchi...... hiện toàn bộ

Neural Networks for Classification and Unsupervised Segmentation of Visibility Artifacts on Monocular Camera Image
Optical Memory and Neural Networks - Tập 31 - Trang 245-255 - 2022
For computer vision systems of autonomous vehicles, an important task is to ensure high reliability of visual information coming from on-board cameras. Frequent problems are contamination of the camera lens, its defocusing due to mechanical damage, image motion blur in low light conditions. In our work, we propose a novel neural network approach to the classification and unsupervised segmentation ...... hiện toàn bộ
Spectral analysis of microdeformations caused by natural and artificial disturbances of the earth crust
Optical Memory and Neural Networks - Tập 19 - Trang 86-96 - 2010
Characteristics of microdeformations caused by earthquakes and underground explosions were analyzed using the laser strainmeter measurements on the shore of the Japanese Sea. Packets of seismic waves from several earthquakes and from an artificial explosion were detected and analyzed with the help of Hilbert-Huang method for investigation of non-stationary and nonlinear processes. It was shown tha...... hiện toàn bộ

The photocatalytic activity of the glass composites with the titan dioxide sol-gel films studies
Optical Memory and Neural Networks - Tập 26 - Trang 216-220 - 2017
The films were drawn on the glass substrates from film-forming sols, created on the basis of chlorides or nitrates. These composites photocatalytic activity dependences on the films thickness and the packaging density of the sol disperse particles in a film layer have been established experimentally.
Direct operation over the UWB optical signal transferred with pseudo-random carrier

Interaction of dielectric substrates in the course of tribometric assessment of the surface cleanliness
Optical Memory and Neural Networks - Tập 17 - Trang 37-42 - 2008
We look into theoretical and experimental aspects of tribometric interaction between two dielectric substrates with identical surfaces in the course of rapid analysis of their cleanliness. It is shown that if the coefficient of sliding friction equals that of static friction the surface is can be defined as being of production grade. The tribometric interaction of the substrates is experimentally ...... hiện toàn bộ
