Embodiment Construction
[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings: this embodiment is implemented under the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to Examples below.
[0018] Such as figure 1 Shown, the present invention comprises the following steps:
[0019] In the first step, for the t-th frame input image, according to the target model established in the initial frame, use the mean shift algorithm to find the state of the target, including the position and target size of the target in the input image;
[0020] The second step is to detect whether occlusion occurs. When the target is detected to be occluded by other objects, the third step is performed; when the target is not detected to be occluded, the state of the target is output;
[0021] The ...

The invention provides a target tracking method based on the modeling of an occluder under the condition of having occlusion, comprising the steps of: for each frame of input image, seeking the state of a target by utilizing a mean shift algorithm according to a target model built at an initial frame; detecting whether the occlusion occurs or not, when detecting that the target is occluded by other objects, modeling the occluder to confirm an area where the target may recur, and when detecting that the target is not occluded, outputting the state of the target; modeling the occluder through looking for the contour of the occluder and realizing the contour of the occluder through an improved active contour method; and searching the target in the area where the target may recur and confirming the target, if the target recurs, outputting the state of the target, if the target does not recur, continuing searching the target in the area where the target may recur, wherein the contour of the occluder is dynamically updated in the searching process of the target to guarantee the accuracy of the searching area.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an object tracking method under occlusion based on occlusion modeling in a dynamic scene. Background technique [0002] Target tracking based on visual information has become one of the hot issues in the field of computer vision, and has been widely used in video surveillance, intelligent transportation, image compression, video retrieval, robot navigation, human-computer interaction, virtual reality and military, etc. in the field. [0003] The occlusion problem is a challenging problem in the target tracking process, which can lead to a decrease in tracking accuracy or even tracking failure, especially when the target is deeply occluded or fully occluded. Aiming at the occlusion problem in the target tracking process, researchers have proposed many solutions. H.T. Nguyen and A.W.M. Smeulders (H.T. Nguyen and A.W.M. Smeulders. "Fast Occluded Object Trackin...
