摘要： In an apparatus and method for creating a three-dimensional model of an object, images of the object taken from different, unknown positions are processed to identify the points in the images which correspond to the same point on the actual object (that is “matching” points), the matching points are used to determine the relative positions from which the images were taken, and the matching points and calculated positions are used to calculate points in a three-dimensional space representing points on the object. A number of different techniques are used to identify the matching points, and a number of solutions are calculated and tested for the relative positions, the solution which is consistent with the largest number of matching points being selected. In one matching technique, edges in an image are identified by first identifying corner points in the image and then identifying edges between the corner points on the basis of edge orientation values of pixels, the edges are processed in strength order to remove cross-overs, the images sub-divided into regions by connecting points at the ends of the edges on the basis of the edge strengths, and matching points within corresponding regions in two or more images are identified.

摘要： A method of generating model data representative of a model in a three-dimensional space of an object from input signals representative of a set of images of the object taken from a plurality of respective camera positions includes the steps of displaying a model image derived from the model data and having a plurality of primitives for viewing by a user, receiving at least one primitive selection signal responsive to user actuation of an input whereby each primitive selection signal identifies a respective selected primitive of the model, and defining a plurality of virtual cameras in the three dimensional space having positions and look directions relative to the model which correspond substantially to those of the respective actual cameras relative to the object. Additional steps include evaluating which of the virtual cameras is an optimum virtual camera for generating a view of the selected primitives, identifying from the camera images a first camera image of the plurality of camera images taken from a camera position corresponding to that of the optimum virtual camera, and determining from the camera images a second camera image as being suitable for matching features in the first camera image and displaying the second camera image for comparison by the user with the first camera image.

摘要： A 3D computer model of an object is generated by calculating the intersections of polyhedra. Each polyhedron defines a volume of 3D space containing at least part of the object. The 3D points of intersection of the planar faces of the polyhedra are calculated and each point is labeled with the planar faces which meet thereat. The points are connected to form a polygon mesh using the labels to determine which points should be connected together. In calculating the points, a volume containing the object is subdivided into parts, each part is tested against the polyhedra and then discarded, subdivided further, or the point of intersection of planar faces within the volume part is calculated. A volume part is discarded if it is outside at least one polyhedron. The volume part is subdivided into further parts if it is intersected by more than a predetermined number of polyhedra faces.

摘要： In an image processing apparatus, a face recognizer is trained using images of one or more faces to generate representation data for the face recognizer characterising the face(s). Face recognition processing is then performed using the representation data. The training and face recognition processing is performed taking into account a person's age.

摘要： A gaze tracking system (1,3,8) is provided which obtains images of an operator (9) and processes the images to associate the images with coordinates of where the operators gaze is directed towards.In order to identify images where an operator is looking in the same direction, images obtained by a camera (8) are first processed using the retinex algorithm. Image patches from the processed image are then compared with stored feature images and an initial classification based upon the correspondence between areas of the processed image and the stored feature images is determined. This initial classification is then further processed and each image is assigned a single classification. The areas identified by different classifications are then determined so that classifications assigned to adjacent images identify points closer together and classifications never assigned to an adjacent images identify points further apart.

摘要： A method providing real-time popularity information regarding TV programs, performed during a short period of time at a server with one or more processors and memory. The server receives current TV viewing information from a plurality of distinct households. The current TV viewing information for a household identifies one or more TV programs that are now showing at the household. The server aggregates the current TV viewing information, thereby identifying one or more currently popular TV programs. The currently popular TV programs have more household viewers than less popular TV programs. The server receives a request from a household seeking identification of currently popular TV programs. The server selects one or more of the currently popular TV programs identified during the aggregation, and sends information to the household. The information identifies the selected one or more currently popular TV programs.
