Srikrishna Bhat 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).

  • Color-based post-processing of images
    Patent number: 9805289
    Abstract: The disclosure includes a system and method for distinguishing objects of similar appearance that vary in color. An image recognition application receives a query image of a plurality of objects, determines a candidate list of indexed images that match an object in the query image based on luminance features, crops an image of the object from the query image to generate a cropped image, computes color features for the object, ranks the candidate list of indexed images based on the color features, and provides the candidate list of indexed images to a user.
    Type: Grant
    Filed: December 18, 2015
    Date of Patent: October 31, 2017
    Assignee: Ricoh Co., Ltd.
    Inventors: Ramya Narasimha, Jorge Moraleda, Kathrin Berkner, Srikrishna Bhat, Sri Kaushik Pavani, Anshul Garg
  • Index image quality metric
    Patent number: 9754237
    Abstract: A system and method that computes a quality score for an index image is disclosed. The method includes receiving an index image, computing a blurriness score of the index image based on variance associated with the index image, computing an image resolution score of the index image based on an area of the index image and a threshold area, computing a feature spread score for the index image using a first plurality of features associated with the index image, computing a feature uniqueness score for the index image using a description associated with each of a second plurality of features and determining a quality score for the index image using the blurriness score, the image resolution score, the feature spread score, and the feature uniqueness score.
