A method for estimating the activity topology of a set of sensed data windows is described. Each of the sensed data windows related to a corresponding sensed region. The method includes the steps of determining a subset of sensed data windows that are not connected; and excluding the subset of sensed data windows from the set of sensed data windows. In one embodiment, the sensed data windows corresponding to image windows such as would be provided by a visual surveillance system.

A method for generating a three dimensional (3D) model of an object from a series of two dimensional (2D) images is described. The series of 2D images depict varying views of the object and have associated camera parameter information. The method includes the steps of tracing the object in a first 2D image selected from the series of 2D images to provide a first set of tracing information, then tracing the object in a second 2D image selected from the series of 2D images to provide a second set of tracing information. The 3D model of the object is then generated based on the camera parameter information and the first and second sets of tracing information.

Method and system for generating a 3D model from images

A method for generating a three dimensional (3D) model of an object is depicted in a two dimensional (2D) image is disclosed, The 2D image includes associated 3D information. The method includes an operator determining a geometric primitive corresponding to shape characteristics of the object and then the generation of the 3D model based on the determined geometric primitive, the 2D image, and the associated 3D information.

Method and system for generating a 3D model

A method () is disclosed of classifying elements in a region within a frame (). The method () creates () a background model () of at least said region based on a statistical function applied to features of elements of said region in a set of frames. A mapping () of features to labels is also received. A difference measure comprising a plurality of difference values is then calculated based on features of elements in the region and features of the background model (). The method () then classifies () elements based upon the difference measure and the mapping ().
