  • CONVEX HULL ENCODING METHOD
    Publication number: 20260059108
    Abstract: A method of forming a convex hull encoding method is provided. The method includes the step of providing a source video clip; splitting the source video clip by a video splitter with a similar scene; slicing each video shots to a preset length video shots; providing down-sampling process, encoding process, decoding process and up-sampling process to obtain the analysis video shots; calculating a quality index between the video shots and the analysis video shots to obtain quality metrics; selecting convex hull points and calculating slopes between the convex hull points; picking operation points with similar slopes to form operation point series and predicting quantizer parameters; encoding the source video clip by the quantization parameters and the corresponding resolutions to obtain a compressed video.
    Type: Application
