20100161702 | Fluid Dynamics Simulator - In some embodiments, the Navier-Stokes matrix A may be developed on the fly using arrays of Dirichlet and von Neumann boundary conditions. As a result, the storage requirements are dramatically reduced and hardware accelerators or single instruction multiple data processors may be used to solve the Navier-Stokes equations. | 06-24-2010 |

20120287124 | GRAPHICAL SIMULATION OF OBJECTS IN A VIRTUAL ENVIRONMENT - A method for simulating a graphical object. The method comprises monitoring approximate distance between a first graphical object and a second graphical object, the first graphical object having at least a first particle and the second graphical object having at least a second particle; detecting a collision (P | 11-15-2012 |
20130278608 | Plant Simulation for Graphics Engines - Plants may be visualized using an inertial animation model with Featherstone algorithm. Different levels of detail may be used for different blocks of plants. | 10-24-2013 |
20140028727 | CONTENT-AWARE IMAGE RESIZING USING SUPERPIXELS - Illustrative embodiments of methods, machine-readable media, and computing devices that provide content-aware image resizing using superpixels are disclosed. In some embodiments, a method may include segmenting a machine-readable image file into a plurality of superpixels, where each of the plurality of superpixels corresponds to a plurality of pixels of the machine-readable image file. The method may also include selecting a target region in the machine-readable image file, where the target region includes the pixels corresponding to a seam of superpixels extending across a dimension of the machine-readable image file. The method may further include selecting a seam of pixels in the target region, where the seam of pixels extends across the dimension of the machine-readable image file, and resizing the machine-readable image file by removing or augmenting the seam of pixels. | 01-30-2014 |

20140036110 | OBJECT SELECTION IN AN IMAGE - Illustrative embodiments of methods, machine-readable media, and computing devices allowing object selection in an image are disclosed. In some embodiments, a method may include detecting one or more features of an object in a machine-readable image file, simulating an electrostatic charge distribution by assigning a virtual point charge to each of the one or more detected features, determining a virtual electric potential field resulting from the simulated electrostatic charge distribution, and selecting a portion of the object in the machine-readable image file that is bounded by an equipotential line in the virtual electric potential field. | 02-06-2014 |
