  • Patent number: 9859694
    Abstract: An insulating film removal method according to the present disclosure includes first, second, and third removal steps. In the first removal step, an insulating film coated on a junction surface and an opposed surface opposed to the junction surface is removed, the junction surface being a surface where a rectangular conductor is joined with another rectangular conductor. In the second removal step, a corner of the rectangular conductor is removed so that a burr is formed on the junction surface and a side surface, the side surface adjoining the junction surface and the opposed surface. In the third removal step, the insulating film coated on the side surface is removed so that a burr is formed on the junction surface side.

  • Patent number: 9609180
    Abstract: Technologies that enable correcting for the non-linear relationship between scene irradiance and digital pixel intensity values of an image of the scene produced by a camera. Imaging noise is used as a signal from which a corrective function is derived. Noise distributions from the image are evaluated to determine the radiometric response function of the camera, from which an inverse response function is computed and used for calibration.

  • Publication number: 20160379366
    Abstract: Systems, methods, and computer-readable storage media are provided for aligning three-dimensional point clouds that each includes data representing at least a portion of an area-of-interest. The area-of-interest is divided into multiple regions, each region having a closed-loop structure defined by a plurality of border segments, each border segment including a plurality of fragments. Point clouds representing the fragments that make up each closed-loop region are aligned with one another in a parallelized manner, for instance, utilizing a Simultaneous Generalized Iterative Closest Point (SGICP) technique, to create aligned point cloud regions. Aligned point cloud regions sharing a common border segment portion are aligned with one another to create a single, consistent, aligned point cloud having data that accurately represents the area-of-interest.

  • Patent number: 8928781
    Abstract: A response function of a device may be determined using rank minimization to transform a problem of determining a response function of the device into a framework of a rank minimization problem. A function is identified that minimizes a rank of an observation matrix which includes data of observations obtained by the device. This transformation may be used to determine a response function of the device under various conditions and to determine response functions of different devices in a unified framework.

  • Publication number: 20140249255
    Abstract: A flame retardant resin composition, containing a thermoplastic resin and a flame retardant, wherein the flame retardant contains a nitrogen-containing structure-introduced phosphorylated lignin derivative, wherein the nitrogen-containing structure-introduced phosphorylated lignin derivative is produced by introducing a nitrogen-containing structure into a lignin derivative and adding a phosphoric acid to the lignin derivative, or by adding a phosphoric acid to a lignin derivative and introducing a nitrogen-containing structure into the lignin derivative, or by introducing a nitrogen-containing structure into and adding a phosphoric acid to a lignin derivative simultaneously, and wherein the lignin derivative is obtained by subjecting a naturally occurring lignin to a treatment for allowing the naturally occurring lignin to be decomposed into small molecules or to be water-soluble.

  • Patent number: 8818132
    Abstract: A “Camera Calibrator” provides various techniques for recovering intrinsic camera parameters and distortion characteristics by processing a set of one or more input images. These techniques are based on extracting “Transform Invariant Low-Rank Textures” (TILT) from input images using high-dimensional convex optimization tools for matrix rank minimization and sparse signal recovery. The Camera Calibrator provides a simple, accurate, and flexible method to calibrate intrinsic parameters of a camera even with significant lens distortion, noise, errors, partial occlusions, illumination and viewpoint change, etc. Distortions caused by the camera can then be automatically corrected or removed from images. Calibration is achieved under a wide range of practical scenarios, including using multiple images of a known pattern, multiple images of an unknown pattern, single or multiple images of multiple patterns, etc.

  • Patent number: 8619153
    Abstract: A method of calibrating a brightness value measured by a camera with an amount of light received by the camera includes creating a series of measurements, wherein for each measurement the amount of light received at an image plane in the camera is controlled to be a known ratio of two opposed irradiance values: a high irradiance value and a low irradiance value. Each ratio is correlated with the brightness value measured by the camera. A function is obtained describing the correlation.

  • Patent number: 8417047
    Abstract: A low light noise reduction mechanism may perform denoising prior to demosaicing, and may also use parameters determined during the denoising operation for performing demosaicing. The denoising operation may attempt to find several patches of an image that are similar to a first patch, and use a weighted average based on similarity to determine an appropriate value for denoising a raw digital image. The same weighted average and similar patches may be used for demosaicing the same image after the denoising operation.

  • Patent number: 8243805
    Abstract: Systems and methods for video completion by motion field transfer are described. In one aspect, a spatio-temporal target patch of an input video data sequence is filled in or replaced by motion field transfer from a spatio-temporal source patch of the input video data sequence. Color is propagated to corresponding portions of the spatio-temporal target patch by treating the transferred motion information as directed edges. These motion field transfer and color propagation operations result in a video completed spatio-temporal target patch. The systems and methods present the video data sequence, which now includes the video completed spatio-temporal target patch, to user for viewing.
