Target tracking method and device

The invention relates to a target tracking method and device, and the method comprises the steps: carrying out the fusion of a short-time filter and a long-time filter, obtaining a mixed filter, enabling the short-time filter to be obtained through the prediction of a current frame image in a video sequence, and enabling the long-time filter to be obtained through the prediction of a current frame image in a video sequence; the long-time filter is a long-time filter obtained last time or is obtained by optimizing the long-time filter obtained last time based on a target template feature pool; and performing target tracking on the current frame image based on the hybrid filter. 本申请关于一种目标跟踪方法和装置，所述目标跟踪方法包括：对短时滤波器和长时滤波器进行融合，得到混合滤波器，其中，所述短时滤波器是基于视频序列中的当前帧图像预测而得到的，所述长时滤波器是前一次得到的长时滤波器或者是基于目标模板特征池对前一次得到的长时滤波器进行优化而得到的；基于所述混合滤波器，对所述当前帧图像进行目标跟踪。
