In object registration and recognition based on a set of known templates, the tremendous set of possible transformations that may relate the template and an observed signature makes any detection and recognition problem ill-defined unless this variability is taken into account. The present invention estimates the deformation that transforms some pre-chosen representation of an object (template) into the current observation. The method employs a set of non-linear operators to replace a high dimensional problem by an equivalent linear problem, expressed in terms of the unknown parameters of the transformation model. The solution is applicable to any homeomorphic transformation regardless of its magnitude. In the special case where the transformation is affine the solution is shown to be exact.

Techniques for area of interest subscription are described herein. In some examples, a requestor, such as a client or other component, may be focused on a particular area of interest within a virtual space. A requestor may, for example, provide information indicating its area of interest within the virtual space. This information may then be used to determine one or more sub-spaces that are at least partially included within the area of interest. The requestor may then be subscribed to each sub-space that is at least partially included within the area of interest. When subscribed to a sub-space, object registration information indicating one or more objects that are registered to the sub-space may be received from one or more sub-space components that are associated with the sub-space.

A mechanism for managing software modules in a VOIP service is discussed. A component management agent is provided for each VOIP software component in the VOIP environment. The component management agent registers with a session management agent which is in communication with a session management software facility. The component management agent accepts registrations from each software module in the component that it represents. The software module registrations indicate the type of objects that the software module supports. Subsequent managed object requests received from the session management facility are automatically directed to the appropriate software modules based on the registration information. Additionally, the session management agent and component management agent perform format conversions for the managed object requests where the session management facility and software modules are utilizing different object systems.

An application programming interface is provided in an object-oriented programming platform for developing applications. A method comprises registering a first object with a second object to observe one or more properties associated with the second object, the second object having a set of methods associated therewith and replacing a first implementation of a method in the set of methods associated with the second object with a second implementation of the method that automatically sends a notification to the first object. The observable objects need not explicitly invoke the observer notifications, avoiding writing of a large amount of code. These observer notifications need only be sent for objects that are actually being observed but are related objects, substantially reducing the performance overhead of needless invocations of the observer notifications without limiting binding between objects.
