Embodiment Construction

[0051] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0052] Such as figure 1 As shown, a kind of video object tracking method based on multi-scale block sparse representation of the present invention, comprises the following steps:

[0053] The first step is to initialize the target feature template, initialize the video target position through the first frame image of the video, and construct the target appearance feature template. Initializing the target feature template is the process of finding the video target position in the first frame of the video and performing initialization. Its initialization target feature template includes the following steps:

[0054] (11) Initialize the position of the target image in the first frame of the video, and find the position of the target im...

Abstract

The invention relates to a video target tracking method based on multi-scale block sparse representation and a system thereof. Compared with the prior art, the invention solves the defect that the conventional target tracking method cannot achieve a better effect. The method comprises the following steps: initializing a target feature template; tracking a target image; updating a target appearance feature template; checking whether a video is read or not. Through the adoption of the method, target tracking precision and efficiency in complex scenes are improved, and the application degree of a target tracking technology in various scenes is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent video, in particular to a video object tracking method and system based on multi-scale block sparse representation. Background technique [0002] Object tracking is an important research direction in the field of computer vision, and it plays a vital role in many practical applications, such as video surveillance, video scene understanding, interactive video processing, etc. At this stage, researchers have proposed a variety of different tracking algorithms, and have achieved certain success in different application scenarios. However, the selection of the local block size of the image in the traditional generative method based on the local sparse representation model directly affects the tracking effect. When the tracked target has experienced a long video sequence, the occlusion, the shape of the target appearance, and the lighting of the environment will all change. Therefore, Object track...
