<P>PROBLEM TO BE SOLVED: To efficiently and exactly track a plurality of dynamic bodies even when the dynamic bodies intersect with one another. <P>SOLUTION: Moving images consisting of consecutive original images P(i) in time series are input in an image input part 110, difference with respect to a background image is taken to generate a dynamic body identification image M(i) for distinguishing background from foreground by a dynamic body identification image generation part 130. A tracker storage part 150 stores blob subsumptive graphics circumscribing contours of individual dynamic bodies in time series. A masking processing part 140 utilizes blob subsumptive graphics of dynamic bodies except a noticing dynamic body Tj at time t(i-1) in the tracker storage part 150 to mask a foreground area of the dynamic body identification image M(i). A blob subsumptive graphic extraction part 170 extracts contours of the foreground area except a masked part as candidate blob subsumptive graphics. A tracker registration part 160 selects a subsequent blob subsumptive graphic Bj(i) with respect to a preceding blob subsumptive graphic Bj(i-1) of the noticing dynamic body Tj from among the candidate blob subsumptive graphics and registers the selected blob subsumptive graphic in the tracker registration part 150. <P>COPYRIGHT: (C)2013,JPO&INPIT |
