Abstract
Способ идентификации личности человека по цифровому изображению лица, включающий поиск лица человека в кадре, выравнивание яркости и цветности изображения, формирование вектора входного изображения путем фильтрации и приведения к бинарному виду, масштабирование изображения до заданного размера по экстремумам интегральных проекций, сегментацию изображения по связности элементов, формирование интегрального индекса на основе векторов геометрических характеристик, осуществление первичного поиска (путем выделения в индексном пространстве тех точек, расстояние которых от точки запросного индекса не превышает заранее заданной величины), осуществление вторичного поиска путем сравнения векторов геометрических характеристик лица и принятие решения о распознавании, отличающийся тем, что, с целью увеличения быстродействия и надежности распознавания, формируют, используя сопряженные цветную и инфракрасную цифровые TV камеры, два идентичных (по размерам и расположению в кадре) изображения распознаваемого лица в видимом и ИК свете, по ИК изображению находят точное расположение центров зрачков глаз, осуществляют вписывание цветного изображения по координатам центров зрачков в эталонный кадр, далее преобразуют цветное изображение в полутоновое и вычисляют нормированное изображение интенсивности градиента яркости, которое приводят к бинарному виду пороговой обработкой на заданном уровне (изображение А), далее вычисляют изображение направлений градиента яркости (изображение В) и пастеризованное цветное изображение (изображение С), в областях единичных элементов в изображении А выделяют зоны несовпадения с сравнивA method of identifying a person’s identity from a digital image of a person, including searching for a person’s face in the frame, aligning the brightness and color of the image, forming the vector of the input image by filtering and converting to binary, scaling the image to a given size by the extrema of the integrated projections, image segmentation by connecting elements, the formation of an integral index based on vectors of geometric characteristics, the implementation of the primary search (by highlighting in the index space of those points whose distance from the point of the query index does not exceed a predetermined value), the secondary search by comparing the vectors of the geometric characteristics of the face and making a recognition decision, characterized in that, in order to increase the speed and reliability of recognition, they are formed using conjugated color and infrared digital TV cameras, two identical (in size and location in the frame) images of a recognizable face in visible and infrared light, find the exact location of the IR image the center of the pupils of the eyes, they enter the color image at the coordinates of the centers of the pupils into the reference frame, then they convert the color image into grayscale and calculate the normalized image of the intensity of the brightness gradient, which lead to the binary form by threshold processing at a given level (image A), then calculate the image of the directions the brightness gradient (image B) and the pasteurized color image (image C), in the areas of individual elements in image A, zones of mismatch are distinguished with comparing
