Person Re-Identification<\/h2>\n\n\n\n

Person re-identification task consists of recognising images of a person of interest across several non-overlapping cameras. It is a challenging task since it presents several issues such as different poses, several illumination variations and camera resolutions, different backgrounds, and several occlusions.<\/p>\n\n\n\n

This task can be helpful in reconstructing the movement of a suspect individual. The main goal of a person re-identification system is to reduce the time required for a human operator to analyse all the available videos. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The recorded videos (acquired by network cameras) are shown to the user. Simultaneously, these videos are processed by the pedestrian detection and bounding box extraction<\/em> module which aims at detecting and extracting pedestrians. The extracted images are, then, stored in a database, called gallery<\/em>. <\/p>\n\n\n\n

The user can select (from a video) the person of interest (query<\/em>) through a user interface. Once the query is selected, the features of query and gallery images are extracted by the feature extraction<\/em> module, and compared by the similarity measure<\/em> module. <\/p>\n\n\n\n

The output of the system is shown to the user. It consists of a list of images ordered by the similarity to the query.<\/p>\n\n\n\n
