Abstract

A real-time algorithm under various complicated sea-sky background, which corresponded to the feature of low contrast around infrared ship and sharp up-and-down motion of camera on boat, was proposed by combining mean-shift and sea-sky-line detection.Firstly, the height of sea-sky-line was extracted by the horizontal projection method, and then the height difference of sea-sky-line in adjacent frames was used to set starting position at current frame, furthermore, the target's feature was described by creating weighted histogram which combined gray-level and gradients orientation information, and finally, mean-shift was used to track the position of target.Experimental results show that this algorithm can track infrared up-and-down motion ship target accurately, and the tracking speed can reach 12 fps.

Key words： mean-shift; infrared ship target; real-time tracking; sea-sky-line; horizontal projection; weighted histogram
