  • Patent number: 11675056
    Abstract: A zoned time-of-flight (ToF) arrangement includes a sensor and a steerable light source that produces an illumination beam having a smaller angular extent than the field of view (FoV) of the sensor. The illumination beam is steerable within the sensor's FoV to optionally move through the sensor's FoV or dwell in a particular region of interest. Steering the illumination beam and sequentially generating a depth map of the illuminated region permits advantageous operations over ToF arrangements that simultaneously illuminate the entire sensor's FoV. For example, ambient performance, maximum range, and jitter are improved. Multiple steering alternative configurations are disclosed, including mechanical, electro optical, and electrowetting solutions.

  • Patent number: 11677944
    Abstract: Embodiments of the present disclosure include a video compression method, an electronic device, and a computer program product. In a video compression method provided by embodiments of the present disclosure, a video is segmented into multiple segments based on a first feature of an object extracted from the video, where the object has a first change in each of the multiple segments, and the first feature identifies a start state and an end state of the first change; the multiple segments are grouped based on a similarity of the first change of the object among the multiple segments; and the video is compressed based on the groups of the multiple segments. In this way, for a video with periodically repetitive content, the video is compressed by retaining a part of representative video segments, which can save storage space and network transmission resources and improve computation efficiency, thereby reducing computation cost.

    Abstract: Disclosed systems and methods provide automatic recognition of information from stationary and/or moving vehicles. A disclosed system includes an image capture device that captures an image of a vehicle surface and thereby generates image data. A processor circuit receives the image data from the image capture device and may process the image data to determine a Department of Transportation (DOT) number. The processor circuit may control the image capture device to capture a plurality of images, to detect and recognize text characters in each of the plurality of images, and to compare probabilities of likely DOT numbers determined from each of the plurality of images. The processor circuit may be further configured to determine DOT numbers from captured images by processing image data using a machine learning algorithm. The system may be configured to be portable and to perform real-time analysis using an application specific integrated circuit (ASIC).

  • Patent number: 11659176
    Abstract: A method of partitioning in video coding for JVET, comprising representing a JVET coding tree unit as a root node in a quadtree plus binary tree (QTBT) structure that can have quadtree or binary partitioning of the root node and quadtree or binary trees branching from each of the leaf nodes. The partitioning at any depth can use asymmetric binary partitioning to split a node represented by a leaf node into two child nodes of unequal size, representing the two child nodes as leaf nodes in a binary tree branching from the parent leaf node and coding the child nodes represented by final leaf nodes of the binary tree with JVET, wherein further partitioning of child nodes split from leaf nodes via asymmetric binary partitioning is allowed recursively along the same branch in any order with symmetric partitioning.

One example method includes obtaining a parent block of a current coding block (parentCurr), and a parent block of a candidate coding block (parentCand). The current coding block and the candidate coding block are each obtained by splitting of the parentCurr and the parentCand, respectively. In one aspect, the current coding block cannot use an intra prediction mode of a potential candidate coding block when parentCand and parentCurr are the same block, a function of a number of quadtree, ternary tree, and binary tree splitting operations is greater than a threshold minus 1, and a split mode of the parent block of the current coding block parentCurr is a ternary tree split.
