Abstract:
1. A visual object tracking method, comprising the steps of: establishing a computer having processor, said processor being configured for: setting an object window having a target in a video image; defining a search window greater than the object window; analyzing an image pixel of the object window to generate a color histogram, wherein the color histogram defines a color filter (CF), and the color filter includes a dominant color characteristic of the target; using the color filter in the object window to generate an object template (O), wherein the object template includes a shape characteristic of the target; using the color filter in the search window to generate a dominant color map, wherein the dominant color map includes at least one candidate block (C); comparing the similarity between the object template and the candidate block to obtain a probability distribution map; and using the probability distribution map to compute the mass center of the target.
