  • Patent number: 9811884
    Abstract: Various techniques are disclosed to suppress distortion in images (e.g., video or still images), such as distortion caused by atmospheric turbulence. For example, similar image blocks from a sequence of images may be identified and tracked along motion trajectories to construct spatiotemporal volumes. The motion trajectories are smoothed to estimate the true positions of the image blocks without random displacements/shifts due to the distortion, and the smoothed trajectories are used to aggregate the image blocks in their new estimated positions to reconstruct the sequence of images with the random displacements/shifts suppressed. Blurring that may remain within each image block of the spatiotemporal volumes may be suppressed by modifying the spatiotemporal volumes in a collaborative fashion.

  • Patent number: 9807424
    Abstract: During a video encoding or decoding process, a predicted prediction block is generated for a CU. The CU may have two or more prediction units (PUs). A computing device selects a neighbor region size. After the computing device selects the neighbor region size, samples in a transition zone of the prediction block are identified. Samples associated with a first PU are in the transition zone if neighbor regions that contain the samples also contain samples associated with a second PU. Samples associated with the second PU may be in the transition zone if neighbor regions that contain the samples also contain samples associated with the first PU. The neighbor regions have the selected neighbor region size. A smoothing operation is then performed on the samples in the transition zone.

    Abstract: The present disclosure pertains to a method for designing cascaded bit sequences for cascaded digital displays. The method avoids unwanted interactions between cascaded sequences in cascaded digital displays. By using sequences with a particular structure, cascaded sequences can be designed such that no sequence is affected by the others. The following rules must be followed in constructing the sequence. First, the display devices must be frame-locked, so that the timing relationship between the sequences is maintained throughout each frame. Second, for each display device, the ratio of bit plane weights must remain constant, regardless of the pixel data displayed on the other display device(s). Third, the amount of bit plane skew must remain constant, regardless of the pixel data displayed on the other display device(s). Fourth, bit plane phased leakage must be compensated for or avoided.

    Abstract: In-stream rolling shutter compensation may be utilized to modify image data to compensate for detected camera motion. An image processor may perform motion matching on image data received from a camera sensor to determine whether and how the camera is moving. Strips of image data are analyzed to find matching locations between the current image and a previous image by generating graphical profiles for each image strip.

A motion vector for the strip may be computed based on spatial distances between the match locations of the current image and corresponding match locations of the previous frame. Image data for the current strip may be modified based on the motion vector to compensate for perceived camera motion as it is written out to memory.

  • Patent number: 9442638
    Abstract: A device may be configured to display a first item in a region of a user interface based on a first value of an index that is associated with the first item. Sensor data may be received from a sensor indicating an angular change of orientation of the device. The index may be incremented to a second value based on the sensor data. The second value may be associated with a second item. The second item may then be displayed in the region of the user interface based on the index being incremented to the second value.

  • Patent number: 9402034
    Abstract: Techniques for adjusting exposure parameters of a camera such that video data captured by the camera may be coded efficiently. A camera with auto exposure control may capture and output frames of video. A pre-processor may estimate brightness of the frames of the video output from the camera. A controller may estimate a rate of brightness change among the frames, and when the rate of change is lower than a predetermined threshold, the controller may reduce sensitivity of the auto exposure control. A coding engine may predictively code the video.

  • Patent number: 9380309
    Abstract: The present invention relates to security video monitoring for and discloses a motion analysis method and a code stream conversion method based on video compression code stream and apparatus thereof. In the invention, a total number of bits or a residual bit number of a macro block in a video I frame is extracted from the video compression code stream; weighted average is performed to the total number of bits or a residual bit number of the macro block whose position corresponds with the current macro block in the latest M frames and a background value is obtained through calculating; a difference value between the total number of bits or the residual bit number of the current macro block and the background value is calculated, and if the difference value is greater than a predetermined first threshold, then a moving object is determined to be detected.

  • Patent number: 9324184
    Abstract: Among other things, one or more techniques and/or systems are disclosed for creating a three-dimensional model of an image. Image data, comprise a series of images of a location, such as along a route, can be received. The image data can comprise a first image element location for a first image element, where the first image element location may correspond to a three-dimensional point in the image, such as a location in the image with a depth from a point of observation. The first image element can be segmented into a first façade plane using the first image element location. The first façade plane can be merged with a second façade plane, resulting in a three-dimensional model of the image. The second façade plane can comprise a second image element, where the image data comprises a second image element location for the second image element.
