The invention discloses a scale adaptive target-tracking method based on a depth characteristic kernel
correlation filter. The method comprises the following steps: inputting an image into a pre-trained
convolution neural network, and extracting depth
convolution features; tracking a target, and estimating the position and scale of the target through the trained model; training the kernel
correlation filter according to the currently detected target position and scale; and updating the kernel
correlation filter through employing an adaptive high-confidence model updating method. According to the invention, the depth
convolution features are extracted, and the adaptive
scale estimation method and the adaptive high-confidence model updating strategy are improved, thereby improving the target tracking robustness under the conditions of complex scenes and appearance changes. The method can achieve the high-efficiency and accurate
processing of the scale change of the target. In addition, the adaptive high-confidence model updating strategy is employed, so the model tracking drift is reduced as much as possible.
