Context based separation of on-/off-vehicle points of interest in videos

Abstract

A method for context based separation between vehicle pixels and background pixels, which may include receiving a first image and a second image, the first image and the second images are of temporarily adjacent to each other and capture a same vehicle and background content. The method may also include obtaining a first bounding box that surrounds at least a part of the vehicle within the first image; wherein the first bounding has a first width and a first height; obtaining a second bounding box that surrounds at least the part of the vehicle within the second image; wherein the second bounding box has a second width and a second height; obtaining a mapping between pairs of initially matched pixels, wherein each pair comprises a first pixel and a second pixel that correspond to same entity portion, wherein the entity portion is a portion of the vehicle or of the background content. The method may also include determining, for each pair of at least some of the pairs, a first normalized relative location of a first pixel of the pair within the first bounding box and a second normalized relative location of a second pixel of the pair within the second bounding box; and determining for the each pair whether the pair is a vehicle related pair or a background content pair.
