  • VIDEO CODING METHOD AND APPARATUS, COMPUTER-READABLE STORAGE MEDIUM
    Publication number: 20210136381
    Abstract: A video coding method includes determining an initial quantization parameter of a to-be-coded key frame in a current to-be-coded group of pictures (GOP), determining a quantization parameter offset of the to-be-coded key frame, and determining a quantization parameter for video coding the to-be-coded key frame according to the initial quantization parameter and the quantization parameter offset.

  • Deblocking filtering method and deblocking filter
    Patent number: 10555007
    Abstract: A deblocking filtering method and a deblocking filter are provided. The method includes: determining, according to a current pixel value of a to-be-filtered pixel in a picture block and pixel values of pixels in a first neighbouring partition of the to-be-filtered pixel, a first filtering offset value of the to-be-filtered pixel; performing prediction on the pixel value of the to-be-filtered pixel according to pixel values of pixels in a second neighbouring partition of the to-be-filtered pixel to obtain a prediction value of filtered value of the to-be-filtered pixel; and determining an actual filtered value of the to-be-filtered pixel according to the current pixel value, the first filtering offset value, and the prediction value of filtered value.
    Type: Grant
