  • Package definition system with non-symmetric functional elements as a function of package edge property
    Patent number: 9760659
    Abstract: A package generation system creates a package definition file for creation of a package flat. The file includes dimensions for cut lines along which the package will be separated from a two dimensional substrate. The flat includes facets and functional elements that connect the facets. The system will identify a pair of the functional elements that have a connecting relationship. The first facet of the pair is a tab structure having a symmetric design, and the second facet of the pair is a receiving structure. If the tab structure and receiving structure are connected to cut lines that intersect at a pivot point, the system will convert the definition of the tab structure from the symmetric design to a non-symmetric design. It will save dimensions for the edges and functional elements in the package design file with the non-symmetric design.

  • Identifying repeat subsequences by left and right contexts
    Patent number: 9760546
    Abstract: A system and method of identifying repeat subsequences having at least a value of x for threshold of different left contexts and a value of y for a threshold of different right contexts for an input sequence are disclosed. The method may include generating a lexicographically sorted suffix array for the input sequence and a longest common prefix array. The suffix array is traversed in lexicographic order comparing the longest common prefix values between consecutive suffixes. Suffixes with the same longest common prefix are representative of occurrence of the same repeat, a higher longest common prefix indicates a new occurrence of a longer repeat, and a lower longest common prefix indicates the last occurrence of a repeat.

  • DOCUMENT BACKGROUND SUPPRESSION PERFORMED DURING COLOR SPACE CONVERSION
    Publication number: 20170255849
    Abstract: An electronic image in a first color space, used by image acquisition devices, is obtained and converted into a second color space with a larger gamut, to produce a second color space image. Corrections are made to the second color space image to produce a corrected image, without performing background suppression. The corrected image is converted into a third color space, used by printing devices, to produce a third color space image, and this process of converting the corrected image into the third color space includes performing background suppression. This process of converting the corrected image into the third color space samples nodes of the second color space values, classifies the nodes as background nodes or non-background nodes, multiplies the second color space values of the background nodes by a percentage less than 100%, and after multiplying, interpolates values between the nodes.

  • System and method for producing seesaw gloss effect and recording medium with seesaw gloss effect
    Patent number: 9756212
    Abstract: A system and method render see-saw scalable gloss effect image patterns on a recording medium by using to two colors to provide one region with a relatively smooth surface, while a second region has a relatively rougher surface. A third region is added composed of a color different than the first two, wherein the third region has a relatively smooth surface where it intersects with the first region and a relatively rougher surface where it intersects with the second region. As the rendered recording medium is tilted at different angles, the image patterns thereon toggle to create a see-saw effect.

    Patent number: 9753893
    Abstract: In rejection sampling of a function or distribution p over a space X, a proposal distribution q(n) is refined responsive to rejection of a sample x*?X to generate a refined proposal distribution q(n+1) selected to satisfy the criteria p(x)?q(n+1)(x)?q(n)(x) and q(n+1)(x*)<q(n)(x*). In a sampling mode, the sample x* is obtained by random sampling of the space X, the rejection sampling accepts or rejects x* based on comparison of a ratio p(x*)/q(x*) with a random draw, and the refined proposal distribution q(n+1) is selected to minimize a norm ?q(n+1)?? where ?<?. In an optimization mode, the sample x* is obtained such that q*=q(n)(x*) maximizes q(n) over the space X, the rejection sampling accepts or rejects x* based on a difference between or ratio of q* and p(x*), and the refined proposal distribution q(n+1) is selected to minimize a norm ?q(n+1)??=max{q(n+1)(x)}.
