  • Publication number: 20140356518
    Abstract: The present invention relates to a method for producing highly-concentrated L-amino acid and riboflavin simultaneously, and a microorganism for simultaneously producing L-amino acid and riboflavin. Specifically, the present invention relates to a modified microorganism for producing L-lysine or L-threonine, and riboflavin simultaneously, wherein the microorganism belonging to Corynebacterium sp. capable of producing L-lysine or L-threonine is modified by enhancing the activity of an enzyme family expressed by a rib operon which contains riboflavin biosynthesis gene family. Also, the present invention relates to a method for the simultaneous production of L-lysine or L-threonine, and riboflavin using the modified microorganism, and relates to a formulation or granular formulation, feed, and feed additive, containing L-lysine or L-threonine, and riboflavin produced from a culture medium of the modified microorganism.

  • Publication number: 20140125666
    Abstract: There are provided a method and an apparatus for generating a depth map of a stereoscopic image that are capable of representing the depth perception of an image more finely by considering not only vanishing points but also fine lines formed within an image. The method includes: generating multiple line segments by grouping multiple edge pixels within an input image based on an intensity gradient direction; merging the multiple line segments based on similarity and thereafter detecting at least one vanishing point in consideration of a result of the merging; and generating an energy depth function on which correlation between the line segments and the vanishing point is reflected and generating a depth map by decoding the energy depth function.

  • Publication number: 20140118507
    Abstract: Provided are an apparatus and a method for manipulating depth of a stereoscopic image that enable a user to manipulate depth of a stereoscopic image easily and intuitively. The apparatus may include: a histogram analyzing unit acquiring a depth distribution chart by performing histogram analysis of a disparity map corresponding to an input image; a Gaussian mixture model (GMM) fitting unit acquiring multiple depth layers by performing GMM fitting of the depth distribution chart; a disparity adjusting unit adjusting at least one of a position and a volume of at least one of the multiple depth layers and calculating a disparity mapping function on which a result of the adjustment is reflected in response to a user request; and a disparity map recalculating unit calculating a new disparity map by optimizing the disparity mapping function.

  • Publication number: 20140099680
    Abstract: The present invention relates to Corynebacterium sp. that is transformed with an Escherichia sp.-derived fructokinase gene to express fructokinase showing a sufficient activity of converting fructose into fructose-6-phosphate, thereby preventing unnecessary energy consumption, and a method for producing L-amino acids using the strain. The transformed Corynebacterium sp. of the present invention is able to express fructokinase from the Escherichia-derived fructokinase gene to prevent unnecessary energy consumption during fructose metabolism, leading to more cost-effective production of L-amino acids. Therefore, it can be widely used for the effective production of L-amino acids.
