  • Patent number: 9530050
    Abstract: A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). The present invention provides a system, method, and computer program product for annotating unindexed documents. Captured digital images of unknown paper documents or portions associated with a user are received with annotations. Features are extracted from the captured digital image and are stored, along with the captured digital image and the annotations.

  • Patent number: 9531999
    Abstract: A smart display detection system is disclosed. The smart display system is configured to allow mobile users to connect with display screens through mobile device cameras. The system can detect the display screens within images captured by the mobile device camera in real time by matching the camera query image with screen images dynamically updated from the display devices. A synchronized time-stamped matching strategy is applied to achieve high performance in detecting the screens playing motion intensive video contents and an aggressive feature selection method is applied to minimize the system uploading bandwidth. The system can accurately find display screens playing either static or dynamic content within an image captured on a mobile device.

  • Publication number: 20160335591
    Abstract: The disclosure includes a system and method for indexing synthetically modified images of a high quality image. An image recognition application receives images of a product, crops background regions from the images, scales the image based on a minimum value among width and height of the image and generates multiple image sizes, blurs the images, brightens the image and indexes the images as being associated with the product. The images can be of box-shaped packages that include four or six images or cylindrical packages that include, for example, eight images of the packages. The images can be indexed in a k-dimensional tree for faster retrieval.

  • Patent number: 9495385
    Abstract: An MMR system for searching across multiple indexes comprises a plurality of mobile devices, a pre-processing server or MMR gateway, and an MMR matching unit, and may include an MMR publisher. The MMR matching unit receives an image from the pre-processing server or MMR gateway and sends it to one or more of the recognition units to identify a result including a document, the page, and the location on the page. The MMR matching unit includes a distributor for distributing the image to corresponding content type specific index tables and an integrator for integrating recognition results. The result is returned to the mobile device via the pre-processing server or MMR gateway. The techniques described herein also include a number of novel methods including a method for processing content-type specific image queries and for processing queries across multiple indexes.

  • Patent number: 9489380
    Abstract: Methods and apparatuses for management of unconsciously captured documents are described. Various documents generated by networked devices are unconsciously captured and stored according to a non-semantic organization. The unconsciously captured documents are archived for possible search and retrieval at a later time. When an event occurs (e.g., lawsuit, audit, change in ownership) that results in a desire for a particular subset of the unconsciously captured documents, the documents are searched for a relevant subset. The subset of documents identified by the search are copied and stored according to a second organization (e.g., subject matter, particular audit). In one embodiment, subsequent unconsciously captured documents are stored according to the first organization. If the subsequent documents satisfy the criteria for the subset of documents, the subsequent documents are copied and stored according to the second organization.

  • Publication number: 20160321518
    Abstract: The disclosure includes a system and method for distinguishing between stock keeping units of similar appearance that vary in size. An image recognition application receives an image including a shelving unit stocking a plurality of items, identifies each item in the image, generates a region of interest for each identified item in the image, identifies a physical dimension of a portion of region depicted in the image, determines a dimension of the region of interest for each identified item and the portion of region in pixels, determines a pixel-to-physical dimension ratio using the dimension in pixels of the portion of region and the physical dimension of the portion of region depicted in the image, and determines a stock keeping unit identifier of each identified item in the image based on the pixel-to-physical dimension ratio and the dimension of the region of interest for each identified item.

  • Publication number: 20160257783
    Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles of polymer materials using 3D printing. A syringe or an inkjet print head prints a solution of prepolymer onto a build plate. The printed prepolymer is exposed to a stimulus whereby the prepolymer is converted to the polymer. After a predetermined time, sequential layers are printed to provide the three-dimensional article. The three-dimensional article can be cured to produce the 3D article made from the final polymer.

  • Publication number: 20160253794
    Abstract: The disclosure includes a system and method for distinguishing between stock keeping units of similar appearance that vary in size. An image recognition application receives an image depicting a plurality of items, the image including a reference marker with a known physical dimension. The image recognition application performs image recognition to identify an item in the image and a region of interest for the identified image. The image recognition application further determines a pixel-to-physical dimension ratio using the dimension of a region of interest of the reference marker and the known physical dimension of the reference marker. Finally, the image recognition application determines a stock keeping unit identifier of the identified item in the image based on the pixel-to-physical dimension ratio and a dimension of the region of interest of the identified item.
