Abstract
An image processing apparatus and a method for generating a three dimensional representation of a scene, which includes a plurality of objects disposed on a plane, is disclosed. The three dimensional representation is generated from one or more video images of the scene, which include the objects on the plane produced from a view of the scene by a video camera. The method includes processing the captured video images to extract image features from each object, comparing image features with sample image features from a predetermined set of possible example objects, and identifying the objects from the comparison of the image features with the sample image features. The method also includes generating object path data, which includes object identification data for each object which identifies the respective object; and provides a position of the object on the plane in the video images with respect to time.
