Dmitry Vladimirovich Cherdakov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Face detection method and apparatus
    Patent number: 8885943
    Abstract: Image fragments are formed in regions corresponding to circles searched from an input image. In a cascade of homogeneous classifiers, each classifier classifies input vectors corresponding to the image fragments into a face type and a non-face type. This procedure is performed on all images included in an image pyramid and the coordinates of a face detected based on the results of the procedures on all images.
    Type: Grant
    Filed: January 12, 2011
    Date of Patent: November 11, 2014
    Assignee: S1 Corporation
    Inventors: Anwar Adkhamovich Irmatov, Dmitry Yurievich Buryak, Dmitry Vladimirovich Cherdakov, Dong Sung Lee
  • Method and apparatus for recognizing a protrusion on a face
    Patent number: 8698914
    Abstract: A method and apparatus for recognizing a protrusion on a face is proposed. The apparatus forms two images, wherein one is formed in a condition in which a target is lighted and another is formed in a condition in which the target is non-lighted. Face regions are detected from the images respectively and then are compared each other. Then, analyzing change in intensity for indicating change in contrast of the compared regions is performed. Based on the result of the analyzing, it is determined whether there is a protrusion in a face presented in the images.
