Abstract
(EN)
Provided are a person re-identification device and method which can acquire an enhanced local feature by using the relationships between local features of each part of a person included in an image, and extract contrastive features of all of the local features on the basis of the difference between the maximum and average of the local features to re-identify the person, and thus can accurately re-identify a person in images in which part of the body is missing, as well as in images including a person having similar features in individual parts.
(FR)
L'invention concerne un dispositif et un procédé de nouvelle identification de personnes, susceptibles d'acquérir une caractéristique locale améliorée en utilisant les relations entre des caractéristiques locales de chaque partie d'une personne comprise dans une image et d'extraire des caractéristiques contrastives de toutes les caractéristiques locales en fonction de la différence entre le maximum et la moyenne des caractéristiques locales pour identifier la personne à nouveau, et susceptibles ainsi d'identifier de nouveau avec précision une personne dans des images où manque une partie du corps, ainsi que dans des images comprenant une personne dont des caractéristiques sont similaires dans des parties individuelles.

본 발명은 이미지에 포함된 사람의 각 부분에 대한 부분 특징들 사이의 관계를 이용하여 강화된 부분 특징을 획득하고, 부분 특징들의 최대 및 평균 사이의 차를 기반으로 전체 부분 특징들의 대조 특징을 함께 추출하여 사람을 재식별 함으로써, 이미지에 신체의 일부가 누락된 이미지뿐만 아니라 부분별로 유사한 특징을 갖는 사람이 포함된 이미지에서도 정확하게 사람을 재식별할 수 있는 사람 재식별 장치 및 방법을 제공한다.
