Object tracking programs, devices and methods using particles assigned any tracker

摘要

To provide an object tracking program, a device and a method for assigning a most suitable tracker when generating a particle without estimating accuracy of a tracker.SOLUTION: A particle is defined as a particle s=(b, tkr) by associating a tracker tkrwith a rectangular region bat a time t. An object tracking device includes response map generation means that generates a response map at the time t by using a correlation filter for a search region based on an image region determined at a time t-1 for each time-series image where an object of tracking is reflected; particle generation means that samples N pieces of rectangular regions bat the time t for M pieces of maximum values p in the response map, assigns arbitrary one from among predetermined tracker candidates to each rectangular region bto generate each particle s, and assigns a value of the response map based on each rectangular region bto each particle sas a weight; and position determining means that determines a particle s^having a maximum weight.SELECTED DRAWING: Figure 3
