METHOD, COMPUTER PROGRAM, AND DEVICE FOR HYBRID TRACKING OF REAL-TIME REPRESENTATIONS OF OBJECTS IN IMAGE SEQUENCE

摘要

The invention in particular relates to the hybrid tracking of representations of objects in an image sequence using at least one key image. After acquiring a first and second image including a representation of the tracked object, a first image portion is identified in the first image, and a second image portion is retrieved from the key image. A relative position of a first image portion of said second image, similar to the first image portion of the first image, is estimated. A second image portion of the first or second image, similar to the second image portion of the key image, is sought. The relative position of the object is then estimated according to the relative positions of the first image portions and the second image portions.
