SYSTEM AND METHOD OF TRACKING AN OBJECT

摘要

The invention relates to detecting and tracking objects in a sequence of images. In particular, a method, software and system for tracking a non-rigid object in a plurality of images. Initially, a first set of parameters for a parameterised shape model are generated (410) based on a first image. Then a second set of parameters are generated (415) for the parameterised shape model by fitting the parameterised shape model to the object in a second image of the plurality of images. This fitting is according to (i) the one or more constraints defined independently of the object or (ii) the first set of parameters. Also, the first and second sets of parameters define a tracking of the non-rigid object between the first and second images.

1. A method of tracking a non-rigid object in a plurality of images including:
generating a first set of parameters for a parameterised shape model by fitting the parameterised shape model to an object in a first image of the plurality of images, wherein the parameterised shape model is fitted to the object in the first image according to one or more constraints defined independently of the object; and generating a second set of parameters for the parameterised shape model by fitting the parameterised shape model to the object in a second image of the plurality of images, wherein the parameterised shape model is fitted to the object in the second image according to:
the one or more constraints defined independently of the object; andthe first set of parameters; wherein the first and second sets of parameters define a tracking of the non-rigid object between the first and second images.
