OBJECT RE-IDENTIFICATION USING SELF-DISSIMILARITY

摘要

A method of identifying an object in an image is disclosed. At least one feature map for each of a plurality of cells in the image is determined. A self-dissimilarity between a first feature map associated with a first one of said cells and a second feature map associated with a second cell, is determined. The self-dissimilarity is determined by determining a sum over thresholds of a difference in area between the first feature map and the second feature map. An appearance signature for the object is formed based on the determined self-dissimilarity. A distance between the appearance signature of the object in the image and appearance signatures of each of a plurality of further objects is determined. The object in the image is identified based on the determined distances.
