Incremental principal component pursuit for video background modeling

Title: Incremental principal component pursuit for video background modeling

An incremental Principal Component Pursuit (PCP) algorithm for video background modeling that is able to process one frame at a time while adapting to changes in background, with a computational complexity that allows for real-time processing, having a low memory footprint and is robust to translational and rotational jitter.

Using dynamic mode decomposition for real-time background/foreground separation in video

Patent Kutz, Jose Nathan ; Grosek, Jacob ; Brunton, Steven ; Fu, Xing ; Pendergrass, Seth

The technique of dynamic mode decomposition (DMD) is disclosed herein for the purpose of robustly separating video frames into background (low-rank) and foreground (sparse) components in real-time. Foreground/background separation is achieved at the computational cost of just one singular value decomposition (SVD) and one linear equation solve, thus producing results orders of magnitude faster than robust principal component analysis (RPCA). Additional techniques, including techniques for analyzing the video for multi-resolution time-scale components, and techniques for reusing computations to allow processing of streaming video in real time, are also described herein.

Electrical-assisted double side incremental forming and processes thereof

Patent Roth, John ; Cao, Jian

A process for forming a sheet metal component using an electric current passing through the component is provided. The process can include providing a double side incremental forming machine, the machine operable to perform a plurality of double side incremental deformations on the sheet metal component and also apply an electric direct current to the sheet metal component during at least part of the forming. The direct current can be applied before or after the forming has started and/or be terminated before or after the forming has stopped. The direct current can be applied to any portion of the sheetmore »« less

System and method for accumulative double sided incremental forming

Patent Cao, Jian ; Malhotra, Rajiv

A forming system includes first and second tools, moving assemblies, and a control unit. The moving assemblies move the first tool and the second tool relative to the sheet. The control unit is configured to control movement of the first tool and the second tool by the one or more moving assemblies by moving at least one of the first tool or the second tool in a first deformation direction to deform the sheet, then moving the first and second tools laterally relative to the sheet to a subsequent location while engaging the sheet, then moving at least one ofmore »« less

System and method for incremental forming

Patent Beltran, Michael ; Cao, Jian ; Roth, John T.

A system includes a frame configured to hold a workpiece and first and second tool positioning assemblies configured to be opposed to each other on opposite sides of the workpiece. The first and second tool positioning assemblies each include a toolholder configured to secure a tool to the tool positioning assembly, a first axis assembly, a second axis assembly, and a third axis assembly. The first, second, and third axis assemblies are each configured to articulate the toolholder along a respective axis. Each axis assembly includes first and second guides extending generally parallel to the corresponding axis and disposed onmore »« less
