Patent number: 8259794Abstract: A method for resource allocation for video encoder to achieve the minimum sequence cost within given resource budgets. Optimal video encoder design by deriving the optimal sequence order and frame type selection is invented. In order to achieve computationally practical resource allocation, the current invention utilizes various encoder model and buffer model. The models allow the optimization procedure to assess the best encoding design without actually performing the computationally expensive encoding. Efficient optimization algorithm is also derived to substantially reduce the computations required to search for the optimal action sequence.Type: GrantFiled: August 27, 2008Date of Patent: September 4, 2012Inventors: Alexander Bronstein, Michael Bronstein

Patent number: 8165204Abstract: A method for resource allocation for video encoder to achieve optimal picture quality within a given resource budget. Making a video encoder utilize the computational complexity, bitrate and other resources in an optimal way while maintaining optimal quality is a complicated optimization problem. A subset of this resource allocation problem, optimizing the tradeoff between bitrate versus quality is called rate-distortion optimization and is performed in most modern encoders. In order to achieve a computationally practical solution of the resource allocation problem, the current invention partitions the video content into a number of regions based on their characteristics and assesses resource allocation among regions to achieve the optimal quality within the resource budget limit. To maintain the computation tractable, the invention relies on bit production model and distortion model for the underlying video content to assess the quality and resource usage instead of actually conducting video compression.Type: GrantFiled: February 29, 2008Date of Patent: April 24, 2012Inventors: Michael Bronstein, Alexander Bronstein

Publication number: 20110170781Abstract: A method determines similarity of objects depicted in images when the images pertain to different modalities. The method includes obtaining images that depict the objects and that pertain to the different modalities. An embedding function is applied to each of the images. The embedding function is selected from a set of two or more embedding functions, each of the embedding functions corresponding to a modality of the different modalities, the selected embedding function corresponding to the modality of the image to which it is applied. Application of the embedding function maps that image to a representation in a representation space such that when the images are mapped to the representation space, a distance between the representations of the images is indicative of a similarity of their depicted objects. The similarity of the depicted objects is determined based on the location of the corresponding representations in the representation space.Type: ApplicationFiled: January 10, 2011Publication date: July 14, 2011Inventors: ALEXANDER BRONSTEIN, Michael Bronstein

Publication number: 20090304085Abstract: An encoder to adaptively alter video deblocking complexity is disclosed in one embodiment of the invention as including a video encoding engine to generate a stream of encoded video data. The encoded video data is characterized by a level of blocking distortion generated during the encoding process. A deblocking filter is coupled to the video encoding engine and reduces the effects of blocking distortion on the encoded video data. The deblocking filter is characterized by a level of deblocking complexity which may depend on the strength and granularity of the deblocking filter applied to the encoded video data. A resource manager is coupled to the deblocking filter and is configured to adaptively alter the deblocking complexity in order to alter the overall computational complexity of the encoder.Type: ApplicationFiled: June 4, 2008Publication date: December 10, 2009Applicant: Novafora, Inc.Inventors: Niranjan Avadhanam, Alexander Bronstein, Michael Bronstein

Patent number: 7623687Abstract: Apparatus for obtaining 3-Dimensional data of a geometric body for matching, and particularly for use in facial matching, comprises a three dimensional scanner for obtaining three-dimensional topographical data of the body, a triangulator for receiving or forming said data into a triangulated manifold, a geodesic converter, for converting the triangulated manifold into a series of geodesic distances between pairs of points of the manifold, and a multi-dimensional scaler, for forming a low dimensional Euclidean representation of the series of geodesic distances, to give a bending invariant representation of the geometric body. In one variant, matching is carried out by taking the principle eigenvalues from the representation and plotting as co-ordinates in a feature space. Tilted or different expression versions of the same face tend to form clusters in the feature space allowing for matching. The apparatus preferably uses the fast marching method for the triangulated domain to obtain the geodesic distances.Type: GrantFiled: September 6, 2005Date of Patent: November 24, 2009Assignee: Technion Research & Development Foundation Ltd.Inventors: Alexander Bronstein, Michael Bronstein, Ron Kimmel

Publication number: 20090161766Abstract: A system and method for processing of video content containing redundant pixels using the picture recombination technique, with one of the main application in video transcoding process. The picture recombination process employs a quality ranking criterion to adaptively select the best region from the co-located regions of redundant pictures as the region for output. An approximation for quality ranking between a decoded picture region and an original picture region has been developed to guide the selection for recombination because the original picture is not available to the transcoder. The quality ranking formula is further modified as a simple linear function depending on the quantization scale, the bit count, and complexity measure of the region.Type: ApplicationFiled: December 21, 2007Publication date: June 25, 2009Applicant: Novafora, Inc.Inventors: Alexander Bronstein, Michael Bronstein
