Abstract

The present invention discloses a target tracking method. The method is implemented in a mobile device having the photographing function. The method comprises the steps of according to a user input, determining a target position within an initial frame, wherein the target position represents a target frame around the center of a target; based on the target position within the initial frame, training and generating a tracker and a detector, wherein the tracker is adapted to track the target in a photographed video in the frame-by-frame manner, and the detector is adapted to conduct the frame-by-frame detection for the target in the photographed video; for each subsequent image frame of the photographed video, tracking by the tracker to obtain the target position of the image frame and outputting a tracking response value; judging whether the tracking response value is greater than or equal to a threshold or not; if yes, continuing the target tracking for the next image frame; if not, starting the detector and outputting the target position of the corresponding image frame by the detector; keeping the detector to run continuously for a predetermined number of frames; and switching to the a tracker for continuously conducting the target tracking. The invention also discloses a corresponding mobile device.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a target tracking method and a mobile device. Background technique [0002] When using mobile devices such as mobile phones for video shooting, photographers often hope that the shooting target can always be kept clear. For this reason, it is necessary to ensure that the focus of the camera of the mobile device is always aligned with the subject target during the shooting process. In reality, due to the irregular movement of the target and the occlusion relationship between different objects, it is very difficult to judge the position of the target. As a result, in many cases, the main target of the shooting becomes blurred due to out-of-focus. [0003] In movie shooting, the adjustment of focus is done manually by experienced photographers. This manual adjustment method is obviously not suitable for the simple operation requirements on mobile devices. Some existing mo...
