  • Patent number: 10313670
    Abstract: Innovations in use of chroma quantization parameter (“QP”) offsets when determining a control parameter for deblock filtering. For example, as part of encoding, an encoder sets a picture-level chroma QP offset and slice-level chroma QP offset for encoding of a slice of a picture. The encoder also performs deblock filtering of at least part of the slice, where derivation of a control parameter considers only the picture-level chroma QP offset. The encoder outputs at least part of a bitstream including the encoded content. As part of decoding, a corresponding decoder sets a picture-level chroma QP offset and a slice-level chroma QP offset for decoding of a slice of a picture, but derivation of a control parameter for deblock filtering considers only the picture-level chroma QP offset.

  • Patent number: 10257449
    Abstract: Embodiments of the present invention are directed to methods and systems for performing automatic noise reduction in video. According to one aspect of the invention, a video noise-reducing system is provided consisting of a noise estimator, a motion classifier, two stages of filters, each including a spatial and temporal filter, and a combiner. The system adapts to noise level and to scene content to find at each location in the image a balance of noise reduction and detail preservation. Temporal Infinite Impulse Response (IIR) filtering provides a high level of detail-preserving noise reduction where motion allows, while non linear spatial filtering provides edge-preserving noise reduction in areas where the temporal filter would introduce motion artifacts. A spatial-temporal combiner provides smooth transition and balance between the two filtering modes; this block also enables use of external cues to produce a visually pleasing output based on ambient conditions.

  • Patent number: 9973782
    Abstract: Techniques described herein are related to coding layer identifiers for operation points in video coding. In one example, a method of decoding video data is provided. The method comprises decoding syntax elements in a video parameter set (VPS) within a conforming bitstream indicating a first operation point having a first set of content. The method further comprises decoding, if present, syntax elements in the VPS within the conforming bitstream indicating hypothetical reference decoder (HRD) parameter information having a second set of content for the first operation point, wherein the conforming bitstream does not include syntax elements in the VPS that duplicate at least one of the first or second set of content for a second operation point, and wherein decoding syntax elements comprises decoding the syntax elements indicating the first operation point and the HRD parameter information only within conforming bitstreams.

  • Patent number: 9940544
    Abstract: In embodiments of event image curation, a computing device includes memory that stores a collection of digital images associated with a type of event, such as a digital photo album of digital photos associated with the event, or a video of image frames and the video is associated with the event. A curation application implements a convolutional neural network, which receives the digital images and a designation of the type of event. The convolutional neural network can then determine an importance rating of each digital image within the collection of the digital images based on the type of the event. The importance rating of a digital image is representative of an importance of the digital image to a person in context of the type of the event. The convolutional neural network generates an output of representative digital images from the collection based on the importance rating of each digital image.

  • Patent number: 9924168
    Abstract: A method and apparatus for three-dimensional and multi-view video coding are disclosed, where the motion vector (MV) or disparity vector (DV) candidate list construction process for a block depends on whether the target reference picture corresponds to an inter-view reference picture or whether the inter-view candidate refers to an inter-view reference picture. In one embodiment, an MV or DV candidate list for a block coded in Merge mode is constructed, and an inter-view candidate in the MV or DV candidate list is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture. In another embodiment, an MV or DV candidate list for a block coded in advanced motion vector prediction mode is constructed, and an inter-view candidate is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture.

  • Patent number: 9918105
    Abstract: In general, the disclosure describes techniques related to block vector coding for Intra Block Copy and Inter modes. In one example, the disclosure is directed to a video coding device comprising a memory configured to store video data and one or more processors. The video coding device is configured to determine a reference picture used for coding the current video block and determine a picture order count (POC) value for the reference picture. In response to the POC value for the reference picture being equal to a POC value for a current picture that includes the current video block, the video coding device sets a value of a syntax element to indicate that a reference picture list includes the current picture. Otherwise, the video coding device sets the value of the syntax element to indicate that the reference picture list does not include the current picture.

  • Patent number: 9911197
    Abstract: Described is a system for detecting moving objects using multi-frame motion history images. An input video sequence of consecutive registered image frames is received. The sequence of consecutive registered image frames comprises forward and backward registered image frames registered to a coordinate system of a reference image frame. Frame differences are computed between each of the consecutive registered image frames and the reference image frame. The frame differences are accumulated based on characteristics of the input video sequence to compute a corresponding motion response value. A selected threshold value is then applied to the motion response value to produce at least one binary image used for detection of moving objects in the input video sequence. Additionally, the invention includes a system for adaptive parameter optimization by input image characterization, wherein parameters that are based on characteristics of the image influence the motion detection process.

  • Patent number: 9904840
    Abstract: A method for fingerprint recognition utilizes an auto encode decode network to perform feature extraction on a first fingerprint image acquired by a fingerprint sensor and a second fingerprint image retrieved from a database. First and second fingerprint features corresponding to the first and second fingerprint images are thus obtained. The first and second fingerprint features may have equal dimensionality. Dimensionality reduction may be performed on the first and second fingerprint features to respectively obtain third and fourth fingerprint features. The third and fourth fingerprint features may have equal dimensionality. A cosine distance between the third and fourth finger print features may determine whether the first fingerprint image and the second fingerprint image belong to a same fingerprint.
