  • Patent number: 9948913
    Abstract: An image processing method and apparatus are provided. The image processing method may include determining whether stereoscopic objects that are included in an image pair and that correspond to each other are aligned on the same horizontal line. The method includes determining whether the image pair includes target objects having different geometric features from those of the stereoscopic objects if the stereoscopic objects are not aligned on the same horizontal line. The method includes performing image processing differently for the stereoscopic objects and for the target objects if the image pair includes the target objects.

  • Patent number: 9734090
    Abstract: Resource use is recorded with a partitioned reference counter. The sum of all resource counter partitions is equivalent to the total references to a resource. When one resource counter partition reaches zero, it is possible that the resource should be destroyed. To determine if this is the case, all other partitions can be checked for a value of zero. If all the partitions are zero, the resource can be destroyed. Coarse grained partitioning and add/release on all partitions can be employed to avoid extra work associated with a local partition reaching zero. Further, destroying or deleting a resource can be accomplished in a manner that avoids a race condition.

  • Publication number: 20170214901
    Abstract: A method and an apparatus for obtaining a depth image by using a time-of-flight sensor may generate a depth image based on a plurality of images in which a motion blur area caused by a movement of an object was corrected. In this case, since the motion blur area is corrected after an initial phase difference of emitted light is compensated, an accuracy of the depth image may be enhanced.

  • Publication number: 20170114110
    Abstract: A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo compared to naturally occurring or recombinant native human erythropoietin. In one embodiment, the protein has a half-life in vivo at least three-fold higher than native human erythropoietin. The fusion protein exhibits enhanced erythropoietic bioactivity compared to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human IgG1, which Fc fragment includes the hinge region, CH2 and CH3 domains. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen risk of an immunogenic response when administered. In one embodiment the hinge region is a human Fc fragment variant having a non-cysteine residue at amino acid 6.

  • Publication number: 20170101713
    Abstract: Embodiments of the present disclosure relate to a showerhead assembly for use in a processing chamber. The showerhead assembly includes a porous insert disposed in a space defined between a gas distribution plate and a base plate to moderate the corrosive radicals resulting from plasma ignition to reduce particle issues and metal contamination in the chamber. The porous insert is a conductive material, such as metal, used to reduce the gap electrical field strength, or may be a dielectric material such as ceramic, polytetrafluoroethylene, polyamide-imide, or other materials with a low dielectric loss and high electrical field strength under conditions of high frequency and strong electric fields. As such, the electrical breakdown threshold is enhanced. The porous insert may reduce and/or eliminate showerhead backside plasma ignition and may include multiple concentric narrow rings that cover gas holes of the gas distribution plate.
