JOINT MINIMUM ENTROPY METHOD FOR SIMULTANEOUS PROCESSING AND FUSION OF MULTI-PHYSICS DATA AND IMAGES
Publication number: 20220012853Abstract: A method for the simultaneous imaging of different physical properties of an examined medium from multi-physics datasets and for digital enhancement and restoration of multiple multidimensional digital images is described. The method introduces nonnegative joint entropy determined as a joint weighted average of the logarithm of the corresponding density of the model parameters and/or images and/or their attributes. The joint entropy measures are introduced as additional constraints, and their minimization results in enforcing of the order and consistency between the different model parameters and/or multiple images and/or their transforms. The method does not require a priori knowledge about specific physical, analytical, empirical or statistical relationships between the different model parameters and/or multiple images and their attributes, nor does the method require a priori knowledge about specific geometric or structural relationships between different model parameters, images, and/or their attributes.Type: ApplicationFiled: June 9, 2021Publication date: January 13, 2022Inventor: Michael S.

Patent number: 10242126Abstract: A method for the simultaneous imaging of different physical properties of an examined medium from the simultaneous joint inversion of multiple datasets of physical field measurements is described. The method introduces Gramian spaces of model parameters and/or their transforms, and Gramian constraints computed as the determinants of the corresponding Gram matrices of the model parameters and/or their transforms. Gramian constraints are introduced as additional regularization terms, and their minimization enforces the correlation between different model parameters and/or their transforms.

Patent number: 9964653Abstract: A method for terrain correction of potential field geophysical survey data measured above an examined medium having density and/or magnetization is described, using potential field data including but not limited to gravity and/or magnetic total field and/or vector and/or tensor data.

The terrain of the examined medium may be described by a spatially variable analytic function of the material properties of the examined medium. The terrain response for at least one component of the measured potential field in at least one receiver location (potential field data) may be calculated using special form of surface integral over the terrain based on 3D analog of the Cauchy-type integrals. This surface integration ensures accurate representation of the terrain response.Type: GrantFiled: December 20, 2012Date of Patent: May 8, 2018Assignee: TechnoImaging, LLCInventor: Michael S. Zhdanov

Patent number: 9020205Abstract: A method of multinary inversion for imaging objects with discrete physical properties of the examined medium is described. The model parameters of the target area are parameterized in terms of a multinary function of the physical properties that accepts a finite number of discrete values from the continuum of at least one physical property. The multinary function is chosen such that the derivative of the multinary function with respect to the physical property is a continuous and known function. The imaging is based on solving the optimization problem for parametric functional of the multinary functions describing the target model parameters. The method can be applied for multi-modal imaging, such that at least one physical property representing the physical properties of the examined medium, may be derived to provide a reconstruction or classification of the physical properties of the examined medium.Type: GrantFiled: August 23, 2013Date of Patent: April 28, 2015Assignee: TechnoImaging, LLCInventors: Michael S.
