  • Patent number: 10901309
    Abstract: 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.

  • Patent number: 9998659
    Abstract: Methods for correcting an image acquired through an Ultra Wide-Angle (UWA) lens is disclosed, where the entire image is mapped via a transformation that substantially improves the perspective, yet maintains all image information. Additional locally adaptive transformations can be applied to regions of interest in the image to fully restore the perspective. This de-warping scheme allows for flexible manipulation of the image while no content would be lost.

  • Patent number: 9414062
    Abstract: 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.

  • Patent number: 9036712
    Abstract: A method for coding video is disclosed. The method generally includes the steps of (A) receiving a video signal having a series of pictures, each of the pictures having a plurality of blocks, (B) analyzing the blocks to forecast if coding the blocks in a zero-residual coding mode would generate a plurality of artifacts, (C) disabling the zero-residual coding mode for the blocks forecasted to generate at least one of the artifacts and (D) enabling the zero-residual coding mode for the blocks forecasted to generate none of the artifacts.

  • Patent number: 9025676
    Abstract: 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.

  • Patent number: 8898432
    Abstract: 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.
