Patent number: 10354159Abstract: Methods of detecting an object in an image using a convolutional neural-network-based architecture that processes multiple feature maps of differing scales from differing convolution layers within a convolutional network to create a regional-proposal bounding box. The bounding box is projected back to the feature maps of the individual convolution layers to obtain a set of regions of interest (ROIs) and a corresponding set of context regions that provide additional context for the ROIs. These ROIs and context regions are processed to create a confidence score representing a confidence that the object detected in the bounding box is the desired object. These processes allow the method to utilize deep features encoded in both the global and the local representation for object regions, allowing the method to robustly deal with challenges in the problem of object detection. Software for executing the disclosed methods within an object-detection system is also disclosed.Type: GrantFiled: September 6, 2017Date of Patent: July 16, 2019Assignee: Carnegie Mellon UniversityInventors: Marios Savvides, Khoa Luu, Chenchen Zhu

Patent number: 10341671Abstract: An image compression method includes compressing an input image with first and second compression methods to generate first and second (e.g., lossless and lossy) compressed images. First and second residual layers are generated, based on a difference between the first and second compressed images. Connected components in the residual layers are identified. Each connected component includes a group of one or more pixels that, when mapped to the second compressed image is connected, in first and second directions, to pixels in the second compressed image. A compressed image is generated, which includes, for a connected component identified in the first residual layer, removing corresponding pixels from the second compressed image, and for a connected component identified in the second residual layer, adding corresponding pixels to the second compressed image. The system and method can thus provide file size savings associated with lossy compression while avoiding character replacement.Type: GrantFiled: April 21, 2017Date of Patent: July 2, 2019Assignee: XEROX CorporationInventors: Sainarayanan Gopalakrishnan, Xing Li, Rajasekar Kanagasabai, Clara Cuciurean-Zapan, Vignesh Doss

Patent number: 10282612Abstract: A method and system for authenticating a user. An expected digital representation of an iris of at least one authentic user is a combination of a first digital representation of an iris of an eye of at least one authentic user and a second digital representation of at least one authentic overlay pattern. In response to a determination that a third digital representation of a captured image of an iris of a user to be authenticated does not match the expected digital representation: the expected digital representation is modified to alter a relative rotational alignment between the representation of the at least one authentic overlay pattern and the expected digital representation of the iris; and a further comparison between the modified expected digital representation and the third digital representation is performed. From the further comparison, an authentication signal indicative of whether authentication of the user has been successful is generated.Type: GrantFiled: October 31, 2018Date of Patent: May 7, 2019Assignee: International Business Machines CorporationInventors: Hamish C.

Patent number: 10259164Abstract: An unorganized point cloud may be created by an optical 3D scanner that scans a physical object, or by computer simulation. The point cloud may be converted into binary raster layers, which encode material deposition instructions for a multi-material 3D printer. In many cases, this conversion—from point cloud to binary raster files—is achieved without producing a 3D voxel representation and without producing a boundary representation of the object to be printed. The conversion may involve spatial queries to find nearby points, filtering material properties of the found points, looking up material mixing ratios, and dithering to produce binary raster files. These raster files may be sent to a multi-material 3D printer to control fabrication of an object. A user interface may display a preview of the object to be printed, and may accept user input to create or modify a point cloud.Type: GrantFiled: June 20, 2017Date of Patent: April 16, 2019Inventors: Christoph Bader, Dominik Kolb, Neri Oxman, James Weaver
