Depth kernel correlation filtering tracking based on multi-template
scale transformation and illumination change in the tracking process
a depth kernel correlation filtering algorithm is proposed based on the multi-template. Firstly
the multi-template algorithm selects the best filtering parameters to optimize the ability of the classifier training samples. The various features are used to optimize the target appearance model which improves the robustness of the multi-feature algorithm. Then
in the tracking process
the depth map information is applied to calculate the target overlap rate which is employed to judge whether the tracking target is occluded. When occlusion occurs
the target search area is redefined
and the target is judge whether to track gain. So it reduces the problem of algorithm drift in the case of occlusion. Finally
according to whether or not occlusion occurs
the classifier parameters and target appearance model are determined whether to update. It improves the reliability of template updates. Using the Princeton database test algorithm
the success rate and accuracy is 85.1% and 98.6% respectively
which is 7.04% and 4.67% higher than the second algorithm respectively. Experiments show that the depth kernel correlation filtering algorithm based on multi-template is superior to the traditional algorithm
