  • Patent number: 11638051
    Abstract: Frames of a video stream collected at first and second points along a video delivery chain are buffered into first and second buffers, respectively, the second point being downstream the video delivery chain from the first point. A control group is identified as a subset of frames of the second buffer. Correlations of extracted features of the control group to extracted features of successive windows of frames of the first buffer are computed, the extracted features being based on spatial information and temporal information of the video stream. A delay between the video stream collected at the first point and the video stream collected at the second point is identified according to a maximum correlation of the correlations.

    Abstract: A method for controlling a speech enhancement process in a far-end device, while engaged in a voice or video telephony communication session over a communication link with a near-end device. A near-end user speech signal is produced, using a microphone to pick up speech of a near-end user, and is analyzed by an automatic speech recognizer (ASR) without being triggered by an ASR trigger phrase or button. The recognized words are compared to a library of phrases to select a matching phrase, where each phrase is associated with a message that represents an audio signal processing operation. The message associated with the matching phrase is sent to the far-end device, which is used to configure the far-end device to adjust the speech enhancement process that produces the far-end speech signal.

  • Patent number: 10045050
    Abstract: A perceptual filter may be implemented to filter one or more spatial frequencies from a video signal that are below a contrast sensitivity limit of a viewer of the video signal. The perceptual filter may be configured to adapt one or more perceptual filter parameters on a pixel-basis based on, for example, content, viewing distance, display density, contrast ratio, display luminance, background luminance, and/or age of the viewer. A spatial cutoff frequency of the perceptual filter may be mapped to a contrast sensitivity. The perceptual filter may be used as a preprocessing step for a video encoder so as to lower an encoded bitrate. Temporal filtering of the video frames may be used to maintain continuity of a spatial cutoff frequency to ensure the perceptual filtering effects are not identified as motion by a video encoder, and the temporal filtering may be restricted to static areas of a frame.

    Abstract: Evaluating coded video by identifying spatial and temporal errors in the reconstructed video. Spatial errors may be identified by evaluating the severity of each individual error and pooling closely located errors to determine whether the collection of errors is noticeable. Temporal errors may be identified by evaluating the quality of each frame and then pooling consecutive frames to determine whether the collection of frames has errors that may be noticeable if the errors persist within the sequence of consecutive frames. The quality of the frames may be analyzed with any conventional analysis metric. In an embodiment, the quality of the frames may be analyzed using a row-column metric. The calculated analysis metrics may be normalized to accurately compare different metric calculations.

    Abstract: A system and method are provided for measuring image quality using an ambient adaptive objective brightness metric. The method accepts an electronically formatted original image (I), and also accepts an electronically formatted brightened image (B), obtained by modifying the original image. For example, the brightened image (B) may be an illumination-modified original image. The method also accepts a relative ambient illumination value (?). A dynamic reference AI=I? is generated, and the brightened image (B) is compared to the dynamic reference (AI).

  • Publication number: 20130329057
    Abstract: Systems and methods for calibrating an electronic display to reduce or eliminate a mura artifact are provided. The mura artifact may be due to differential behavior of common voltage layers (VCOMs) in the electronic display. One method for reducing or eliminating the mura artifact may involve turning on an electronic display and programming pixels the electronic display to a uniform gray level. An initial luminance value may be determined and, after waiting a period of time, a subsequent luminance of the pixels may be measured. When a difference between the subsequent luminance and initial luminance is within a threshold, the mura artifact may be understood to have settled and the electronic display may be calibrated.
