1. An object tracking method comprising:
- receiving frames of data containing compressed-domain image information of an object;
performing an object segmentation using the compressed-domain image information, the object segmentation comprises;
extracting motion vectors from the frames of data;
estimating a global motion using the motion vectors; and
subtracting the global motion from the motion vectors to generate an object motion result; and
using the object motion result to conduct an object tracking.

Abstract
An object tracking method may include: receiving frames of data containing image information of an object; performing an object segmentation to obtain an object motion result; and using the object motion result to conduct an object tracking. In particular, the object segmentation may include: extracting motion vectors from the frames of data; estimating a global motion using the motion vectors; and subtracting the global motion from the motion vectors to generate an object motion result.

9. An object tracking method comprising:
-
receiving frames of data containing compressed-domain information of an object;
performing an object segmentation based on motion vectors of the series of frames of data in a compressed domain to generate an object segmentation result with the effect of an estimated global motion removed from the object segmentation result; and
conducting a similarity analysis of the object segmentation result and an initial object model. - View Dependent Claims (10, 11, 12)
