Publication number: 20180075611Abstract: One embodiment of the present invention sets forth a technique for estimating a head pose of a user. The technique includes acquiring depth data associated with a head of the user and initializing each particle included in a set of particles with a different candidate head pose. The technique further includes performing one or more optimization passes that include performing at least one iterative closest point (ICP) iteration for each particle and performing at least one particle swarm optimization (PSO) iteration. Each ICP iteration includes rendering the three-dimensional reference model based on the candidate head pose associated with the particle and comparing the three-dimensional reference model to the depth data. Each PSO iteration comprises updating a global best head pose associated with the set of particles and modifying at least one candidate head pose. The technique further includes modifying a shape of the three-dimensional reference model based on depth data.Type: ApplicationFiled: November 27, 2017Publication date: March 15, 2018Inventors: Gregory P.

Publication number: 20170263041Abstract: A system, method and computer program product are provided for generating one or more values for a signal patch using neighboring patches collected based on a distance dynamically computed from a noise distribution of the signal patch. In use, a reference patch is identified from a signal, and a reference distance is computed based on a noise distribution in the reference patch. Neighbor patches are then collected from the signal based on the computed reference distance from the reference patch. Further, the collected neighbor patches are processed with the reference patch to generate one or more values for the reference patch.Type: ApplicationFiled: January 31, 2017Publication date: September 14, 2017Inventors: Iuri Frosio, Jan Kautz

Publication number: 20170004089Abstract: A patch memory system for accessing patches from a memory is disclosed. A patch is an abstraction that refers to a contiguous, array of data that is a subset of an N-dimensional array of data. The patch memory system includes a tile cache, and is configured to fetch data associated with a patch by determining one or more tiles associated with an N-dimensional array of data corresponding to the patch, and loading data for the one or more tiles from the memory into the tile cache. The N-dimensional array of data may be a two-dimensional (2D) digital image comprising a plurality of pixels. A patch of the 2D digital image may refer to a 2D subset of the image.Type: ApplicationFiled: June 30, 2015Publication date: January 5, 2017Inventors: Jason Lavar Clemons, Chih-Chi Cheng, Daniel Robert Johnson, Stephen William Keckler, Iuri Frosio, Yun-Ta Tsai

Patent number: 8864665Abstract: A portable monitoring device for monitoring of the short term, mid term and long term risks of Sudden Infant Death Syndrome (SIDS) and to estimate the risk of onset of positional plagiocephaly. The monitoring device acquires one or more signals associated to the typical breath and positioning patterns of an infant through a tri-axial accelerometer, and registers the data in electronic format, where statistical analysis of the signal and pattern recognition are performed in real time by a processing unit. The device monitors the breath activity of an infant in various conditions, alerting a caregiver when a potentially dangerous situation is detected. The monitoring is attached to the clothes of the infant. Statistical analysis of the registered data is performed for quantifying the long term SIDS risk, the risk of plagiocephaly and for optimizing the functional parameters of the monitoring device.Type: GrantFiled: September 7, 2011Date of Patent: October 21, 2014Assignee: Alta Lab S.r.l.Inventors: Giuseppe Rotondo, Iuri Frosio
