Patent number: 10584972Abstract: A system and method for mapping, tracking, positioning, and navigating in GPS-denied or GPS-inaccurate areas features accurate and automatic generation and update of a pedestrian lane map based on crowd-sourcing unique path features (UPFs) in combination with associated path estimates from a plurality of mobile devices. Searching and matching newly generated UPFs and associated path estimates, to a pedestrian lane map with known UPFs and associated lanes (or lane estimates) provides simultaneous localization and mapping (SLAM) of mobile devices in GPS-denied or GPS-inaccurate areas, including indoors, underground; dense urban streets with high buildings, natural canyons, and similar environments. UPFs are robust to noise and orientation invariant, enabling operation on low cost mobile device sensors and handling of real life human behavior. The innovative UPFs and pedestrian lane map enable route finding, generating guiding instructions, tracking, and analysis of pedestrian traffic.Type: GrantFiled: September 1, 2016Date of Patent: March 10, 2020Assignee: Oriient New Media Ltd.Inventors: Amiram Frish, Dror Reif, Michael Balter

Patent number: 9972062Abstract: Flood-fill techniques and architecture are disclosed. In accordance with one embodiment, the architecture comprises a hardware primitive with a software interface which collectively allow for both data-based and task-based parallelism in executing a flood-fill process. The hardware primitive is defined to do the flood-fill function and is scalable and may be implemented with a bitwise definition that can be tuned to meet power/performance targets, in some embodiments. In executing a flood-fill operation, and in accordance with an example embodiment, the software interface produces parallel threads and issues them to processing elements, such that each of the threads can run independently until done. Each processing element in turn accesses a flood-fill hardware primitive, each of which is configured to flood a seed inside an N×M image block. In some cases, processing element commands to the flood-fill hardware primitive(s) can be queued and acted upon pursuant to an arbitration scheme.Type: GrantFiled: November 21, 2014Date of Patent: May 15, 2018Assignee: INTEL CORPORATIONInventors: Alon Gluska, Niraj Gupta, Mostafa Hagog, Dror Reif

Patent number: 9934573Abstract: Technologies for adjusting a perspective of a captured image for display on a mobile computing device include capturing a first image of a user by a first camera and a second image of a real-world environment by a second camera. The mobile computing device determines a position of an eye of the user relative to the mobile computing device based on the first captured image and a distance of an object in the real-world environment from the mobile computing device based on the second captured image. The mobile computing device generates a back projection of the real-world environment captured by the second camera to the display based on the determined distance of the object in the real-world environment relative to the mobile computing device, the determined position of the user's eye relative to the mobile computing device, and at least one device parameter of the mobile computing device.Type: GrantFiled: September 17, 2014Date of Patent: April 3, 2018Assignee: Intel CorporationInventors: Dror Reif, Amit Moran, Nizan Horesh

Patent number: 9761059Abstract: Computer-readable storage media, computing device and methods associated with dynamic modification of a rendering of a physical scene. In embodiments, one or more computer-readable storage media may have instructions stored thereon which, when executed by a computing device, may provide the computing device with a dynamic augmentation module. The dynamic augmentation module may, in some embodiments, cause the computing device to receive a manipulation of a physical scene. In response to receipt of the manipulation, the dynamic augmentation module may cause the computing device to dynamically modify a rendering of the physical scene. In some embodiments, this may be accomplished through real-time application of one or more virtual articles to the rendering of the physical scene or alteration of one or more virtual articles added to the rendering of the physical scene. Other embodiments may be described and/or claimed.Type: GrantFiled: May 5, 2014Date of Patent: September 12, 2017Assignee: Intel CorporationInventors: Kobi Nistel, Barak Hurwitz, Gila Kamhi, Dror Reif, Vladimir Cooperman

Patent number: 9514085Abstract: Method, apparatus, and systems employing novel dictionary entry replacement schemes for dictionary-based high-bandwidth lossless compression. A pair of dictionaries having entries that are synchronized and encoded to support compression and decompression operations are implemented via logic at a compressor and decompressor. The compressor/decompressor logic operatives in a cooperative manner, including implementing the same dictionary update schemes, resulting in the data in the respective dictionaries being synchronized. The dictionaries are also configured with replaceable entries, and replacement policies are implemented based on matching bytes of data within sets of data being transferred over the link. Various schemes are disclosed for entry replacement, as well as a delayed dictionary update technique. The techniques support line-speed compression and decompression using parallel operations resulting in substantially no latency overhead.Type: GrantFiled: October 1, 2011Date of Patent: December 6, 2016Assignee: Intel CorporationInventors: Ilan Pardo, Ido Y.

Patent number: 9389779Abstract: Technologies for depth-based gesture control include a computing device having a display and a depth sensor. The computing device is configured to recognize an input gesture performed by a user, determine a depth relative to the display of the input gesture based on data from the depth sensor, assign a depth plane to the input gesture as a function of the depth, and execute a user interface command based on the input gesture and the assigned depth plane. The user interface command may control a virtual object selected by depth plane, including a player character in a game. The computing device may recognize primary and secondary virtual touch planes and execute a secondary user interface command for input gestures on the secondary virtual touch plane, such as magnifying or selecting user interface elements or enabling additional functionality based on the input gesture.
