Person Re-Identification

Person Re-Identification is a challenging computer vision task that can provide useful tools for many security applications of video-surveillance, for example on-line tracking of individuals over different, non-overlapping cameras, and off-line retrieval of the video sequences containing an individual of interest, whose image is given as a query.


People Search with Textual Queries on Clothing Appearance

It is a recent computer vision task, related to person re-identification. It consists of retrieving images of individuals that match a textual query describing the clothing appearance. This can be useful, e.g., in forensic video analysis, when only textual descriptions of individuals of interest, given by witnesses, can be available.
