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 4):
The image-based object tracking method according to  claim 3 , wherein the step of analyzing the position projecting relationship between the current frames in the current image and the previous frames in the previous image to assign the object numbers of the observed objects to the current frames of the current image comprises:\n calculating a plurality of current object central points of the current frames of the current image and calculating a plurality of previous object central points of the previous frames of the previous image; and determining whether the current frames correspond to the previous frames according to the current object central points and positions of the previous frames in the previous image and according to the previous object central points and positions of the current frames in the current image.
