Tracking Objects Based on Multiple Particle Filters for Multipart Combined Moving Directions Information

الملخص EN

Object tracking is an important procedure in the computer vision field as it estimates the position, size, and state of an object along the video’s timeline.

Although many algorithms were proposed with high accuracy, object tracking in diverse contexts is still a challenging problem.

The paper presents some methods to track the movement of two types of objects: arbitrary objects and humans.

Both problems estimate the state density function of an object using particle filters.

For the videos of a static or relatively static camera, we adjusted the state transition model by integrating the movement direction of the object.

Also, we propose that partitioning the object needs tracking.

To track the human, we partitioned the human into N parts and, then, tracked each part.

During tracking, if a part deviated from the object, it was corrected by centering rotation, and the part was, then, combined with other parts.
