Abstract: Method and system for on-chip processing to obtain an EDOF image combines interferometry and imaging so the two operations do not interfere with one another but, rather, work together to create an in-focus, true color image of a three-dimensional object. This image has no significant artifacts and requires only limited processing. In addition, a coarse depth map is created in the process which may also be helpful in subsequent usage of the acquired image. A CMOS pixel-array sensor includes circuitry to implement processing at the pixel level.

Abstract: A method for determining a perturbation energy of a quantum state of a many-body system includes constructing a wave function that approximates the quantum state by adjusting parameters of the wave function to minimize an expectation value of a zeroth-order Hamiltonian. The zeroth-order Hamiltonian explicitly depends on a finite mass of each of a plurality of interacting quantum particles that form the many-body system, the quantum state has a non-zero total angular momentum, the wave function is a linear combination of explicitly correlated Gaussian basis functions, and each of the explicitly correlated Gaussian basis functions includes a preexponential angular factor. The perturbation energy is calculated from the wave function and a perturbation Hamiltonian that explicitly depends on the finite mass of each of the plurality of interacting quantum particles. The perturbation energy may be added to the minimized expectation value to obtain a total energy of the quantum state.

Abstract: Described herein are means for generation of self-taught generic models, named Models Genesis, without requiring any manual labeling, in which the Models Genesis are then utilized for the processing of medical imaging.

Such a system operates by cropping a sub-volume from each 3D input image; performing image transformations upon each of the sub-volumes cropped from the 3D input images to generate transformed sub-volumes; and training an encoder-decoder architecture with skip connections to learn a common image representation by restoring the original sub-volumes cropped from the 3D input images from the transformed sub-volumes generated via the image transformations.
