  • Patent number: 11122290
    Abstract: A video decoding method performed by a decoding apparatus includes the steps of: deriving control points (CP) for a current block; acquiring movement vectors for the CPs; deriving a sample unit movement vector in the current block on the basis of the acquired movement vectors; and deriving a prediction sample for the current block on the basis of the sample unit movement vector. According to the present invention, it is possible to effectively perform, through sample unit motion vectors, inter-prediction not only in a case where an image in the current block is plane-shifted but also in a case where there are various image distortions.

  • Patent number: 11064190
    Abstract: Described herein is a multi-view display (based on spatial and/or temporal multiplexing) having an optimization mechanism that dynamically adjust views based upon detected state changes with respect to one or more views. The optimization mechanism determines viewing parameters (e.g., brightness and/or colors) for a view based upon a current position of the view, and/or on the multi-view display's capabilities. The state change may correspond to the view (a viewer's eye) moving towards another viewing zone, in which event new viewing parameters are determined, which may be in anticipation of entering the zone. Another state change corresponds to more views being needed than the display is capable of outputting, whereby one or more existing views are degraded, e.g., from 3D to 2D and/or from a personal video to a non-personal view. Conversely, a state change corresponding to excess capacity becoming available can result in enhancing a view to 3D and/or personal.

  • Patent number: 11051047
    Abstract: A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

  • Patent number: 10999583
    Abstract: Aspects of the present disclosure provide techniques for reducing latency and improving image quality of a viewport extracted from multi-directional video communications. According to such techniques, first streams of coded video data are received from a source. The first streams include coded data for each of a plurality of tiles representing a multi-directional video, where each tile corresponding to a predetermined spatial region of the multi-directional video, and at least one tile of the plurality of tiles in the first streams contains a current viewport location at a receiver. The techniques include decoding the first streams and displaying the tile containing the current viewport location. When the viewport location at the receiver changes to include a new tile of the plurality of tiles, retrieving and decoding first streams for the new tile, displaying the decoded content for the changed viewport location, and transmitting the changed viewport location to the source.

  • Patent number: 10992921
    Abstract: An aerial vehicle is outfitted with two or more digital cameras that may be continuously calibrated. The aerial vehicle may include one or more markings provided on portions of a frame, a control surface or another component that are within fields of view of the digital cameras. Based on an initial calibration of the digital cameras, intrinsic and extrinsic parameters of the digital cameras may be determined. Using the intrinsic and extrinsic parameters, locations of the markings may be determined. Subsequently, after the aerial vehicle has engaged in flight operations, images captured of the marking may be used to determine whether the digital cameras remain properly calibrated, and whether images captured using the imaging devices may be relied upon in determining ranges to objects or for any other purpose. A correction factor may be generated based on any differences between projections of the markings within the respective images.

  • Patent number: 10965913
    Abstract: A person is detected from a moving image of the monitoring area, and position information on the person is acquired. Temporal statistical processing is performed on the position information, statistical information relating to a staying situation of the person is acquired in accordance with setting of a target period of time for the statistical processing, and thus a heat map moving image is generated. Furthermore, a mask image corresponding to a person image area is generated at every predetermined point in time based on the position information on the person. A monitoring moving image that results from superimposing the heat map image and the mask image onto a background image is generated and is output at every predetermined point in time.

  • Patent number: 10924664
    Abstract: Enhanced battery edge detection devices, systems, and techniques are described herein. During an inspection process, an inspection system controls one or more non-visible light sources to illuminate a battery installed in an electronic device. The illumination activates a reflective pigment applied to at least a portion of an edge of the battery. The inspection system controls one or more cameras to capture at least one image of the illuminated battery installed in the electronic device. The at least one image is processed to detect the edge of the battery and to measure a gap size between the edge of the battery and a region of the electronic device proximate the edge of the battery. The electronic device and battery are flagged for further inspection if the measured gap size is below a threshold indicative of a zero gap event.

  • Patent number: 10911757
    Abstract: Picture processing methods and apparatuses in an image or video encoding or decoding system for processing a picture partitioned into multiple non-overlapped Coding Tree Units (CTUs). Input data of a current CTU is received and split into one or more CUs. A CU entirely inside picture boundaries is split by a splitting type selected from a first set of splitting types, and a CU not entirely inside the picture boundaries is split by a splitting type selected from a second set of splitting types. The second set of splitting type comprises at least two different splitting types to provide flexibility for each out-of-bounds CU to select a splitting type. The current CTU is encoded or decoded when it is partitioned into leaf CUs for prediction and transform processing.
