Method for quantitative criterion based transformation of the video information alphabet

Abstract

Subject of study: technologies implemented in modern video coding algorithms to ensure the appropriate level of reliability in the conditions of their compact presentation. The goal is to develop a technology for transforming the alphabet of a video information based on a quantitative criterion while ensuring the required quality in networks. Objectives: to formulate requirements to video images in dynamic video surveillance systems; to analyze the existing factors leading to an imbalance between the compression and quality characteristics of existing video coding algorithms; to develop a technology for transforming the alphabet of a video information based on a quantitative criterion (attribute) for the best presentation of the encoded data; to develop a mathematical model for the formation of a quantitativeindicator for the transformation of the video images; to analyze the effectiveness of using the developed mathematical model for the formation of a quantitative indicator to provide the required trustworthiness of data for the video information resource; to assess the effectiveness of the developed technology for transforming the original message in terms of a quantitative indicator to ensure the best presentation of the encoded data; to investigate the dynamics of the probabilistic and statistical characteristics of the original message as a result of transformation according to the quantitative criterion of the significance of the elements. The research methods: compression coding methods implemented on the basis of the JPEG algorithms. The research results: a new approach has been proposed based on the transformation of the encoded alphabet of data by use of a quantitative criterion. A mathematical model has been developed for the formation of a quantitative attributethat determines the significance of the elements of the original message. Conclusions. A technology has been developed for transforming the alphabet of the original message, which allows creating conditions for a more profitable presentation of the encoded data due to a significant increase in the dynamic range of probabilistic and statistical characteristics for the transformed message while ensuring the required level of video image quality.

Software and Hardware Module for Automated Detection and Recognition of Interest Objects to Increase the Level of Processing Efficiency and Reliability of Aerial Reconnaissance Data

“…The analysis of the latest scientific researches shows that nowadays compression technologies are actively used to ensure the necessary level of operational efficiency of data processing generated by the sensors of the air reconnaissance system at the UAS [11][12][13]. This is due to the need for a compact presentation of encoded ARD to overcome the imbalance between vol'capacity of transmitted intelligence data and bandwidth of video data transmission lines (data link).…”

“…This is due to the fact that most of the sensors of the target equipment of the UAS form intelligence information in this data compression format [5,6,10]. However, the disadvantage of using algorithms of the above-mentioned family is low resistance to errors in video data transmission lines, which can lead to significant distortion and destruction of video images and, as a result, to the impossibility of further decryption of ARD [11,13]. Thus, the use of the specified algorithms does not allow to ensure the required level of reliability of intelligence information received from UAS.…”

Модель Організації Скритого Каналу Передачі Даних В Інформаційно-Телекомунікаційних Мережах Спеціального Призначення

“…Для організації скритого каналу передачі даних пропонується використовувати синтез методів стеганографічного приховування та кластерного аналізу. Це пов'язано з тим, що на сьогоднішній день технології кластерного аналізу набули широкого розвитку та досить активно використовуються для обробки даних як інструмент, що дозволяє при досить простій алгоритмічній реалізації створити умови для більш вигідного представлення інформаційного ресурсу [35][36][37][38][39][40][41].…”
