Long-time target tracking method based on TLD framework

The invention relates to the technical field of computer vision, and provides a long-time target tracking method based on a TLD framework. The method comprises the steps: firstly, a target region is selected in a starting frame, and a detection module and a tracking module are initialized; then, the tracking module estimates the position and size of the target in the current frame according to theposition information of the target in the previous frame by adopting a fast discriminant scale space algorithm, and a tracking failure detection mechanism is designed to judge whether tracking succeeds or not; if the tracking fails, the detection module detects the current frame according to the training sample and finds out the possible position of the target; and then the comprehensive module processes tracking and detection results, judges whether a target exists in the current frame and judges the position of the target, designs a shielding discriminator and judges whether the target is shielded, updates the shie
