Abstract:
(EN) Disclosed are a system and method for extracting feature values of a digital video, and a system and method for determining the similarity between digital videos by using the method. The system for extracting feature values of a digital video comprises a still image extraction unit, an image normalization unit, a pixel feature value extraction unit, a feature region setting unit, a pixel search unit, and a position value extraction unit. The still image extraction unit extracts a still image by decoding a video; the image normalization unit normalizes the extracted still image to a predetermined low resolution; the pixel feature value extraction unit extracts a predetermined pixel feature value from the normalized still image; the feature region setting unit sets a predetermined number of pixels having larger pixel feature values as a feature region; the pixel search unit searches for pixels of the normalized still image according to a predetermined order; and when a feature region is searched, the position value extraction unit extracts the position value of the searched feature region.
(FR) L'invention concerne un système et un procédé permettant d'extraire les valeurs de caractéristiques d'une vidéo numérique, ainsi qu'un système et un procédé permettant de déterminer la similitude entre des vidéos numériques au moyen du procédé. Le système permettant d'extraire les valeurs de caractéristiques d'une vidéo numérique comprend une unité d'extraction d'image fixe, une unité de normalisation d'image, une unité d'extraction de valeur de caractéristique de pixel, une unité de configuration de zone de caractéristiques, une unité de recherche de pixels et une unité d'extraction de valeur de position. L'unité d'extraction d'image fixe extrait une image fixe en décodant une vidéo. L'unité de normalisation d'image normalise l'image fixe extraite à une basse résolution prédéterminée. L'unité d'extraction de valeur de caractéristique de pixel extrait une valeur de caractéristique de pixel prédéterminée à partir de l'image fixe normalisée. L'unité de définition de zone de caractéristiques définit un nombre prédéterminé de pixels ayant des valeurs de caractéristiques de pixels supérieures en tant que zone de caractéristiques. L'unité de recherche de pixels recherche les pixels de l'image fixe normalisée selon un ordre prédéterminé et, lorsqu'une zone de caractéristiques est recherchée, l'unité d'extraction de valeur de position extrait la valeur de position de la zone de caractéristiques recherchée.
(KO) 디지털 동영상 특징값 추출 시스템 및 방법, 및 상기 방법을 이용한 디지털 동영상 유사도 판단 시스템 및 방법이 개시된다. 디지털 동영상 특징값 추출 시스템은, 정지영상 추출부, 영상 정규화부, 화소 특징값 추출부, 특징 영역 설정부, 화소 검색부, 및 위치값 추출부를 포함한다. 정지영상 추출부는 동영상을 디코딩하여 정지영상을 추출하고, 영상 정규화부는 추출된 정지영상을 미리 설정된 저해상도로 정규화하고 화소 특징값 추출부는 정규화된 정지영상에서 미리 설정된 화소 특징값을 추출하고, 특징 영역 설정부는 화소 특징값이 큰 미리 설정된 수의 화소를 특징 영역으로 설정하고 화소 검색부는 미리 설정된 순서에 따라 정규화된 정지영상의 화소를 검색하며, 위치값 추출부는 특징 영역이 검색되는 경우 검색된 특징 영역의 위치값을 추출한다.
