Patent number: 10901309Abstract: Systems and methods for calibrating an image projection system, using image capture devices are disclosed. In particular, Wide-Angle (WA) and Ultra Wide-Angle (UWA) lenses can be utilized to eliminate need for traditional test patterns and tedious alignment settings. That is particularly useful for automatic calibration of projection sources that may require frequent adjustments on the field. Geometric mapping techniques combined with image analytics allow identifying parallel lines in an image captured from a scene. Coordinates of vanishing points corresponding to pairs of parallel lines provide sufficient information to determine orientation of the image projection system in space.Type: GrantFiled: January 12, 2018Date of Patent: January 26, 2021Assignee: GEO SEMICONDUCTOR INC.Inventors: Zorawar S.

Patent number: 9414062Abstract: In some embodiments, a motion estimation search window cache is adaptively re-organized according to frame properties including a frame width and a number of reference frames corresponding to the current frame to be encoded/decoded. The cache reorganization may include an adaptive mapping of reference frame locations to search window cache allocation units (addresses). In some embodiments, a search window is shaped as a quasi-rectangle with truncated upper left and lower right corners, having a full-frame horizontal extent. A search range is defined in a central region of the search window, and is laterally bounded by the truncated corners.Type: GrantFiled: December 3, 2012Date of Patent: August 9, 2016Assignee: GEO SEMICONDUCTOR INC.Inventors: Sorin C.

Patent number: 9025676Abstract: A method, system and device are provided for pre-filtering device for filtering a video signal prior to digitally encoding. The method includes receiving at least one input picture and at least one reconstructed picture from an encoding process and performing an in-loop temporal filtering process using at least one input picture and at least one reconstructed picture from an encoding process to output a pre-filtered video signal for use in an encoding process. The result is enabling an encoding process to produce an output with increased temporal correlation between adjacent pictures regardless of the coding type, since the artifacts introduced by the encoding process are also considered by the process.Type: GrantFiled: July 10, 2012Date of Patent: May 5, 2015Assignee: GEO Semiconductor Inc.Inventors: José Roberto Alvarez, Lulin Chen, Alexandros Michael Tourapis

Patent number: 8898432Abstract: Systems and methods for folding a single instruction multiple data (SIMD) array include a newly defined processing element group (PEG) that allows interconnection of PEGs by abutment without requiring a row or column weave pattern. The interconnected PEGs form a SIMD array that is effectively folded at its center along the North-South axis, and may also be folded along the East-West axis. The folding of the array provides for north and south boundaries to be co-located and for east and west boundaries to be co-located. The co-location allows wrap-around connections to be done with a propagation distance reduced effectively to zero.Type: GrantFiled: October 25, 2011Date of Patent: November 25, 2014Assignee: Geo Semiconductor, Inc.Inventor: Woodrow L.
