  • Patent number: 12170780
    Abstract: The disclosure provides a sample adaptive offset (SAO) encoder. The SAO encoder includes a statistics collection (SC) block and a rate distortion optimization (RDO) block coupled to the SC block. The SC block receives a set of deblocked pixels and a set of original pixels. The SC block categorizes each deblocked pixel of the set of deblocked pixels in at least one of a plurality of band and edge categories. The SC block estimates an error in each category as difference between a deblocked pixel of the set of deblocked pixels and corresponding original pixel of the set of original pixels. The RDO block determines a set of candidate offsets associated with each category and selects a candidate offset with a minimum RD cost. The minimum RD cost is used by a SAO type block and a decision block to generate final offsets for the SAO encoder.

  • Patent number: 12159499
    Abstract: A garage door is controlled to open using an audio/video (A/V) recording and communication device. The device detects a vehicle within an area about the garage door and receives, using a camera, image data representative of an object associated with the vehicle. The device also compares the image data representative of the object associated with the vehicle with previously stored image data and identifies the object based on the comparing of the image data representative of the object with the previously stored image data. The device also authenticates an electronic device within the vehicle that is associated with the object by wirelessly communicating with the electronic device and determines, based at least in part on the authenticating of the electronic device within the vehicle, that the vehicle is an authorized vehicle. The device also transmits an actuation command to the garage door to cause the garage door to open.

  • Patent number: 12155850
    Abstract: Reconstructing a second component signal relating to a second component of a multi-component picture from a spatially corresponding portion of a reconstructed first component signal and a correction signal derived from a data stream for the second component promises increased coding efficiency over a broader range of multi-component picture content. By including the spatially corresponding portion of the reconstructed first component signal into the reconstruction of the second component signal, any remaining inter-component redundancies/correlations present such as still present despite a possibly a priori performed component space transformation, or present because of having been introduced by such a priori performed component space transformation, for example, may readily be removed by way of the inter-component redundancy/correlation reduction of the second component signal.

  • Patent number: 12149701
    Abstract: An image encoder or decoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, predicts a first set of samples for a first partition of a current picture with one or more motion vectors including a first motion vector and predicts a second set of samples for a first portion of the first partition with one or more motion vectors from a second partition different from the first partition. The samples of the first set of samples of the first portion of the first partition and of the second set of samples of the first portion of the first partition are weighted. A motion vector for the first portion of the first partition is stored which is based on one or both of the first motion vector and the second motion vector. The first partition is encoded or decoded using at least the weighted samples of the first portion of the first partition.

  • Patent number: 12130858
    Abstract: Disclosed herein are methods and systems of metadata management for reviewing data from microscopy experimental sessions. Image data from an experimental session is stored in an archive at one or more filepath locations, either locally or on a network. Metadata associated with the image data is stored in a database with a reference to the filepath where the raw image is stored, such that the metadata is associated in the database with the image data. A user can perform post-experimental filtering, sorting, and searching of the underlying image data using the metadata, which allows the image data to be analyzed without duplication of the image data and without manual review of each individual image. The filtered data is presented in an interactive timeline format.

  • Patent number: 12120309
    Abstract: A method of video decoding is provided. In the method, a coded video bitstream of a current picture is received. The current picture is divided into a plurality of rows of coding tree units (CTUs). Coding blocks in a first CTU row of the plurality of rows of CTUs are decoded based on motion vector information stored in a history-based motion vector prediction (HMVP) buffer. The motion vector information stored in the HMVP buffer is updated as the coding blocks in the first CTU row are decoded. The HMVP buffer is updated to include the motion vector information of the coding blocks in a first CTU of the first CTU row after the coding block at an end of the first CTU row is decoded.

  • Patent number: 12106643
    Abstract: A security system monitors a behavior of a person included in a plurality of camera images captured continuously in time series by a surveillance camera. The security system performs tracking processing of detecting each person region of a person included in a plurality of camera images, and identifying a person included in the plurality of camera images in time series based on person image data included in the person region. When the identification by the tracking processing transitions to failure in the middle, it is determined that a person having suspicious behavior is included in the camera image. When it is determined that the suspicious behavior is included, alert information may be notified from an output device.

  • Patent number: 12101458
    Abstract: A system and method for determining the performance of a video codec for real-time communication applications. A set of network conditions is used to simulate certain typical real-world network conditions. A coded video stream is transmitted from the transmitting end to the receiving end under these conditions. The end-to-end latency and received video fluency are measured along with a set of existing video quality measures by a video codec performance evaluation system including a network model and a video codec quality analyzer. The decodable frame ratio, latency and video fluency are used as the performance metrics for real-time communication video quality evaluation. The video codec performance evaluation system does not send any video data over a network when it determines the real-time communication quality of the video codec.

  • Patent number: 12094173
    Abstract: A method for direct write printing of an electrical or optical element based upon a generated master actual position map and a master expected position map is disclosed. The generated master actual position map is generated by efficiently stitching together a number of images using a hierarchical stitching process. Once the desired location of the electrical or optical element is determined by comparing the master actual position map with the master expected position map, a corresponding toolpath for a direct write printer is generated. The direct write printer then direct write prints the electrical or optical element using the generated toolpath. By using different types of inks, the electrical element may be a trace, a resistor, an inductor, a transformer, a capacitor, or some combination thereof. In like manner, the optical element may be a waveguide, a beam-splitter, a phase shifter, an optical attenuator, an interferometer, or some combination thereof.
