Abstract: A method and system are presented for real time Super-Resolution image reconstruction. According to this technique, data indicative of a video frame sequence compressed by motion compensated compression technique is processed, and representations of one or more video objects (VOs) appearing in one or more frames of said video frame sequence are obtained. At least one of these representations is utilized as a reference representation and motion vectors, associating said representations with said at least one reference representation, are obtained from said data indicative of the video frame sequence. The representations and the motion vectors are processed, and pixel displacement maps are generated, each associating at least some pixels of one of the representations with locations on said at least one reference representation. The reference representation is re-sampled according to the sub-pixel accuracy of the displacement maps, and a re-sampled reference representation is obtained.

Abstract: A memory storage device readable by machine is presented, the device tangibly embodying a sequence of depth maps associated with a continuous scene sequence of digital 2D images of a predetermined resolution, the sequence of depth maps including at least one restricted redundancy depth map of a resolution lower than the predetermined resolution of the 2D images. The depth maps may be used for 3D (i.e. stereo) visualization.

Abstract: A method of automatically focusing an imaging system and an imaging system having automatic focusing use an image of an object created by the imaging system to determine an optimum focus position. The present invention employs one or both of an edge detection approach and an image comparison approach to automatic focusing. The edge detection approach comprises computing an edge density for each image of a set of images of the object, and using a focus position corresponding to an image of the set that has a greatest computed edge density as the optimum focus position. The image comparison approach comprises adjusting a focus position for the image of the object by a difference between focus positions for a reference image and a closely matched image of a typical object. The imaging system has a computer program comprising instructions that implement the method of the invention.
