Target tracking method and device based on parallel processing

The invention discloses a target tracking method and device based on parallel processing. The method comprises the following steps: extracting a first HOG feature of a target to be tracked in a current frame; performing position filtering on the first HOG feature based on a position filter template to obtain the position of the to-be-tracked target in the current frame; a second thread used for scale filtering is started, and the second thread extracts a second HOG feature of the to-be-tracked target in the current frame based on the position of the to-be-tracked target in the previous frame; performing scale filtering on the second HOG feature based on a scale filter template to obtain the scale of the to-be-tracked target in the current frame; and updating the position filter template and the scale filter template based on the position and the scale of the to-be-tracked target in the current frame. The method can adapt to target tracking in a complex environment. 本发明公开了一种基于并行处理的目标跟踪方法及装置，所述方法包括：提取待追踪目标在当前帧中
