This thesis is part of a project that is concerned with the study of object re-identification and damage detection applied to images of personal belongings, in particular bikes. Object re-identification (ReID) is a computer vision based technology which aims at associating a particular object across different scenes and camera views, in order to assess whether a specific object is present in an image or video sequence regardless of the background or the object angle and position. Damage detection (DT) is the automatic process of identifying the presence of a damage on an object, and eventually assess the location and the type of the damage.
