Abstract:
A method, a system, and a computer-readable recording medium for image-based object tracking are provided. The method includes following steps. A video stream including a plurality of images is received. The video stream is generated through photographing an enclosed space by an image capturing device, and a moving range of a plurality of observed objects is limited to the enclosed space. A plurality of moving objects are detected from the video stream, and frames associated with each of the moving objects are generated for the images. The images include a current image and a previous image. By analyzing position projecting relationship between current frames in the current image and previous frames in the previous image, linking relationship between the current frames in the current image and the observed objects is established. The observed objects in the enclosed space are tracked according to the established linking relationship.

Claim (Index 14):
The image-based object tracking system according to  claim 13 , wherein the processor projects the current object central points to the previous image, determines whether any of the previous frames comprises more than one of the current object central points, and determines whether the current object central points are all located within the previous frames.
