Abstract:
An object tracking apparatus (1) includes: a first generation unit (221-224) for generating, based on a first position information (PIt-τ) related to a position of an object (Ot-τ) in a first image (IMt-τ) captured at a first time (t-τ) and a second position information (PIt) related to a position of an object (Ot) in a second image (IMt) captured at a second time (t), first and second feature vectors (CVt-τ, CVt); and a second generation unit (225) for generating, as a correspondence information (AM) indicating a correspondence relationship between the object in the first image and the object in the second image, an information that is obtained by a calculation processing using the first and the second feature vectors.
