  • Patent number: 10068137
    Abstract: The invention relates to a method for automatic detection and tracking of one or multiple objects of interest in a video sequence comprising several successive frames (1) captured with a moving camera, comprising:—segmenting (32) each frame into regions depending on color and producing a segmented image (1?);—deducing (34) from each segmented image (1?) a region adjacency graph (11) comprising nodes and edges, wherein each node defines a region and each edge links two nodes of adjacent regions; wherein the region adjacency graphs (11) form a set of region adjacency graphs;—extracting (36) from the set of region adjacency graphs frequent spatio-temporal patterns (13);—determining (38) degrees of dissimilarity between the trajectories of the extracted frequent spatio-temporal patterns (13) between successive frames (1); and—clustering (39) the frequent spatio-temporal patterns (13) to produce at least one cluster (25, 26, 27) corresponding to one object of interest among said one or multiple objects of interest
