Precisely localizing in an image a set of feature points that form a shape of an object, such as car or face, is called alignment. Previous shape alignment methods attempted to fit a whole shape model to the observed data, based on the assumption of Gaussian observation noise and the associated regularization process. However, such an approach, though able(More)
An articulated object can be loosely defined as a structure or mechanical system composed of links and joints. The human body is a good example of a nonrigid, articulated object. Localizing body shapes in still images remains a fundamental problem in computer vision , with potential applications in surveillance, video editing/annotation, human computer(More)
