A computerized method for model-less segmentation and registration of ultrasound (US) with computed tomography (CT) images of an organ with a fluid filled chamber. The method is based on correlating between the US image(s) and the CT image(s) by processing the US image(s) by iteratively expanding the CT image segment so that the expanded CT image segment is correlated with the visual boundaries of the US image segment; transforming the CT image(s) according to an estimated US transducer position and estimated US beam direction related to the US image(s) so that at least one of shape and volume of the organ in the CT image is adapted with at least one of shape and volume of the organ of the US image, to form a CT image representation which is correlated with US image(s).

A method for generating and viewing on a handheld device a 3-D augmented reality feature containing a rich media message that is linked to a physical object comprises the steps of: a) by a first user: i. Taking a picture of a physical object; ii. selecting an augmented reality theme; iii. attaching the rich media animated object to the image taken, in the desired position and location on the physical object; iv. generating a reach media message from the augmented reality image obtained in step (iii); iv. optionally attaching an additional file to the rich media message; v. Transferring the physical object to a second user; and vi. sending to said second user a message via a communication channel, which contains the augmented reality rich media; b) by the second user (the recipient): vii. viewing the physical object received from the first user, using an AR viewer in the mobile phone camera, thereby to see the augmented reality rich media appearing on said physical object.

A method of dynamic load-balancing in a PC-based computing system employing a multiple GPU-based graphics pipeline architecture supporting multiple modes of GPU parallelization. During the execution of the graphics application, the stream of geometrical data and said graphics commands is analyzed, and the mode of parallelization of the GPUs during each frame, is determined using results of the analysis of the stream of geometrical data and graphics commands, and one or more policies for determining the mode of parallelization. The stream of geometrical data and graphic commands is distributed to the GPUs according to the determined mode of parallelization. During the generation of each frame, one or more of GPUs are used to process the stream of geometrical data and graphic commands, or a portion thereof, while operating in the parallelization mode, so as to generate pixel data corresponding to at least a portion of an image of 3D object. The pixel data output is transferred from one or more of the GPUs and composing a frame of pixel data, representative of the image of the 3D object. The frame of pixel data is displayed on a display surface of the PC-based computing system.
