Abstract
An image target tracking method and system thereof are provided in the present disclosure. The image target tracking method includes the following steps: obtaining a target initial position, and performing a sparse sampling according to the target initial position; dividing sampling points into foreground sampling points and background sampling points; clustering adjacent foreground sampling points according to a spatial distribution of the foreground sampling points in order to obtain a clustering result containing a plurality of clusters; performing a robust estimation according to the clustering result in order to determine a relative position between a target and a camouflage interference in an image; and generating a prediction trajectory, correlating an observation sample position with the prediction trajectory to generate a correlation result, and determining whether the target is blocked and tracking the target according to the correlation result.
