Abstract

The invention discloses a multi-characteristic matching multi-target tracking method based on Hough forest. A conserved and reliable track fragment is obtained through double-threshold correlation. A positive and negative sample set is generated in an online manner according to a sample selecting principle. The Hough forest is constructed. Through Hough forest learning, training samples with color, shape, class and motion information are divided to different leaf nodes. Statistics information of the leaf node is used for forecasting an association probability of two track fragments. When a reliable long-track fragment is obtained, the reliable long-track fragment is converted to a re-matching problem between the tracks. Two manners of similarity measuring and characteristic point matching are used. The reliable long-track fragment is associated to a real track through the association probability, thereby finishing matching. The multi-characteristic matching multi-target tracking method has advantages of settling problems of error accumulation and low tracking precision, improving capability for processing target shielding and deformation, and realizing multi-target tracking in a complicated scene.

Description

technical field [0001] The invention relates to a multi-feature matching multi-target tracking method based on Hough Forest. Background technique [0002] With the popularity of video surveillance systems, the research on target detection and tracking has gradually become a hot research direction in the field of computer vision, and multi-target tracking, as an important branch, mainly locates targets and forms motion trajectories to further confirm each The identity of the target; at the same time, multi-target tracking is also a multi-disciplinary interdisciplinary research topic including image processing, pattern recognition, probability theory and statistical analysis, system control theory, etc., which has strong practical application and academic value. [0003] In recent years, the idea of ​​Tracking by Detection has attracted the attention of many scholars, and gradually formed a target tracking method based on the idea of ​​data association. This method is mainly ...
