  • Patent number: 9600868
    Abstract: Systems and methods are disclosed for performing local adaptive weighting upsampling. An image may be converted into a color space representation. The color space representation of the image may then be divided into the individual color spaces. Upsampling may then be performed on the individual color planes. The upsampling may include resizing the color planes by adding pixels to the color planes. Local processing of the different color spaces may be performed to estimate values for the added pixels. Upon generating the estimated values, the estimated values may be refined by determining which known pixel values from the original image have the highest degree of influence on a newly added pixel.

  • Patent number: 9600883
    Abstract: A comprehensive strategy is used to determine valid reference time-concentration curves (TCCs) from image data. The image data corresponds to a series of image scans acquired over time for an area of interest of a patient to which a contrast agent was previously administered. The image scans are initially registered to a common coordinate system. Then, observed potential reference TCCs in the image scans are compared to modeled reference TCCs to determine if the potential reference TCCs are plausible reference TCCs. Thereafter, any plausible reference TCCs are evaluated to determine if they contain residual, isolated motion artifacts. If a plausible reference TCC does not include any motion artifacts, the plausible reference TCC is considered a valid reference TCC. If a plausible reference TCC is determined to include motion artifacts, the plausible reference TCC is modified to a valid reference TCC by removing the motion artifacts, or otherwise the plausible reference TCC is rejected.

  • Patent number: 9600900
    Abstract: Systems to measure muzzle exit conditions of for ammunition improve fire control solutions and reduce shot-to-shot dispersion in both conventional and air-burst programmable ammunition. A first system measures muzzle velocity and, when firing “post-shot” programmable ammunition, the system calculates a unique time-of-flight optimized for the actual muzzle velocity and transmits the time to detonate signal by using either optically or radio-frequency signals that represent an optimized time of burst to a projectile. A second system measures muzzle velocity coupled to a ballistic calculator and, when used with ammunition having ferrous characteristics, the force is applied to exiting ammunition to slow or increase the muzzle velocity to a consistent, standardized target velocity. The systems are separately or in combination incorporated into kits that readily improve the performance of weapon systems.

  • Patent number: 9600903
    Abstract: RGB image signals are inputted. B/G ratio is calculated based on B image signal and G image signal. G/R ratio is calculated based on the G image signal and R image signal. In a feature space formed by the B/G ratio and the G/R ratio, a third process for increasing a difference in saturation between coordinates in a first observation area and coordinates in a second observation area is performed. In the first observation area, coordinates corresponding to a portion infected with H. pylori are distributed. In the second observation area, coordinates corresponding to a portion in which eradication of the H. pylori infection has been successful are distributed.

  • Patent number: 9600905
    Abstract: An input unit receives designation of an evaluation target screen by a user. A color-scheme information acquisition unit acquires color-scheme information. An attractiveness calculation unit calculates an attractiveness by using the color-scheme information. An importance degree storage unit holds importance degree information representing a relative degree of importance of each of the used colors and corresponding to information for which each of the used colors is used. A color-scheme appropriateness judgment unit calculates ordinal rank of the importance degree information associated with each of the used colors, calculates ordinal rank of the attractiveness associated with each of the used colors, and outputs a judgment result indicating whether or not the ordinal rank of the importance degree information associated with each of the used colors coincides with the ordinal rank of the attractiveness associated with the used color. An output unit displays the judgment result.

  • Patent number: 9600907
    Abstract: Paintbrush and liquid simulation techniques are described. In one or more implementations, input is received to perform brush strokes with a virtual paintbrush on a virtual canvas. For virtual paint on the virtual canvas, lifelike paint qualities are simulated. However, the lifelike paint qualities are simulated solely for the virtual paint that is within a region of the canvas. The lifelike paint qualities are not simulated for virtual paint located outside the region. As part of simulating the interaction between the virtual paint, the virtual paintbrush, and the virtual canvas, various parts of the simulation may be performed by different processing units. For example, bristles of the virtual paintbrush may be simulated utilizing a first processing device such as a central processing unit (CPU). A second processing unit, such as a graphics processing unit (GPU), may be employed to simulate the lifelike effects of the virtual paint.

  • Patent number: 9600908
    Abstract: A method for paint color recommendation. The method obtains measures of an environment to be painted and trains a learned model to input data received from customers including data representing each customer's initial color paint and pigment selection, and one or more of: a customer perceptual, a customer context, and environment measure (P/C/E data) to generate a sparse matrix. One or more paint vendors may then use the generated sparse matrix to determine a color pigment recommendation from a pigments color space for a customer. From a user selected color/pigment, and using the learned model, the method maps the selection, together with the user's P/C/E data back to the color/pigments space. User feedback representing a degree of satisfaction that the recommended color pigment applied to the user environment has matched the user's initial color paint and color pigment selection is elicited.
