Patent number: 11343650Abstract: An unconstrained saddle point of a function is obtained by computing a combination of a first subspace for minimization, and a second subspace for maximization. A combination of a current location including a first and second current location within the first and second subspace is iteratively selected. From the current location, a combination of a step-size including a first and second step-size along a first and second direction of the first and second subspace, is computed. The first and second step-size is to a next first and second location within the first and second subspace. The current location is set to a next location including the next first and second location. The combination of the first and second subspace is according to the next location. The iterations terminate when the next location meets a requirement denoting the unconstrained saddle point. The location indicating the unconstrained saddle point is provided.Type: GrantFiled: December 23, 2020Date of Patent: May 24, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Yoni Choukroun, Michael Zibulevsky

Patent number: 9036885Abstract: A method of projection domain processing based on a local transform and shrinkage for use in reconstructing digital images from a set of projections, the method including providing a target image of a target object, providing projection data of the target object, producing filtered projection data by applying a sparsifying transform and a shrinkage function to the projection data, followed by an inverse of the sparsifying transform, producing a restored image by applying a reconstruction transform to the filtered projection data, comparing the restored image to the target image, and producing an optimized projection domain shrinkage function by adapting the shrinkage function to minimize differences between the restored image and the target image. Related apparatus and methods are also described.Type: GrantFiled: October 23, 2013Date of Patent: May 19, 2015Assignee: Technion Research & Development Foundation LimitedInventors: Michael Elad, Joseph Shtok, Michael Zibulevsky

Publication number: 20050151084Abstract: A method is provided for estimating a line of flight of coincident photons in an emission tomography system, the system including an array of gamma radiation detectors and a line of flight estimator, the method comprising taking responses resulting from detection of a pair of photons by a pair of opposite detectors, consisting of a first detector and a second detector, in the array that are on opposite sides of the line of flight and estimating directly the line of flight by the line of flight estimator, taking into account responses from both detectors. There is further provided a gamma camera for use in an emission tomography system, the camera comprising two or more stacked layers of solid state gamma radiation detectors.Type: ApplicationFiled: August 10, 2004Publication date: July 14, 2005Inventors: Michael Zibulevsky, Alexander Bronstein, Michael Bronstein, Y.
