  • Processing Regions Of A Video
    Publication number: 20220327797
    Abstract: A method includes optimizing a video quality of a video data stream received by a user in a video conference. A region of at least one frame of the video data stream may be sampled. The sampling rate may be variable based on the rate of change of objects in the video data stream. A video quality metric corresponding to the video quality of the video data stream may be calculated. The video quality of the video data stream may be adjusted based on the video quality metric. Another method includes retrieving a video and detecting one or more moving regions of interest (ROIs). Each of the ROIs is tagged with metadata configured to allow users to interact with the ROI, and the detected ROIs and their corresponding metadata are stored in a file. Based on the file, playback of the video and movement of the ROIs may be synchronized.

  • Method for preparing silicone hydrogels
    Patent number: 11433629
    Abstract: The invention provides a contact lens manufacturing method for cast-molding of silicone hydrogel contact lenses having enhanced oxygen permeability without adversely affecting desirable lens mechanical properties (e.g., modulus). A method of the invention comprises adding a small amount of a radical scavenger (e.g., H-TEMPO) in a polymerizable composition for cast-molding of SiHy contact lenses) to provide the resultant polymerizable composition with a bi-phase curing profile at a curing temperature of from about 45° C. to about 100° C. With such a bi-phase curing profile, the resultant polymerizable composition can be thermally cured at the curing temperature to form a SiHy contact lens having an oxygen permeability higher than that for a polymerizable composition having the substantially identical composition excepting being free of any radical scavenger.

    Abstract: Implementations of the present disclosure provide a method for backup destination selection, an electronic device, and a computer program product. In one method, in a storage device set, a first group of candidate subsets is obtained, and the number of storage devices included in candidate subsets in the first group of candidate subsets is determined based on the number of copies specified by a backup task. A first group of subset codes of the first group of candidate subsets is determined. A second group of subset codes is generated according to the first group of subset codes, and codes in the second group of subset codes uniquely identify the candidate subsets. Based on the first group of candidate subsets and a second group of candidate subsets corresponding to the second group of subset codes, a target subset is selected as a backup destination of the backup task.
