Technique of estimation of probability of recognition of text symbols on noisy images

Abstract: В работе представлена методика экспериментальной оценки вероятности распознавания текстовых символов (букв и цифр) на зашумленных изображениях. Приведено описание специального программного обеспечения для проведения экспериментальных исследований. В результате обработки результатов экспериментальных исследований получены аналитические соотношения для расчета вероятности правильного распознавания оператором букв и цифр (шрифт − Times New Roman, кегель − 14 пунктов), выводимых на экран монитора, в зависимости от… Show more

“…If inequality (3) is not fulfilled and the determination is necessary, the circuit considered in [16,17] is assembled, and at the point of disconnection of the ATMS at the -th frequency, a signal from the signal generator is supplied to the line under investigation and the voltage of this signal is measured with a probe at two points: near the supply signal to the line at point T1 ( ) and at the boundary of the CZ at point T2 ( ). The measurement results…”

“…Practically on any object of informatization there are certain technical means (TM) related to auxiliary technical means and systems (ATMS): telephones, fire and burglar alarm sensors, dispatch (loud-speaking) communication systems, office equipment, communication systems, etc. [1,5,6,[17][18][19]. In normal operation, these vehicles can form technical channels of information leakage.…”
