  • Method and device for generating a predicted value of an image using interpolation and motion vectors
    Patent number: 10097826
    Abstract: A method and device for generating a predicted value of image to generate a predicted value of a current block during image encoding or decoding is disclosed, where the method includes determining a searching scope, wherein a plurality of motion vectors are included in the searching scope, performing up-sampling interpolations on first reference blocks corresponding to the motion vector in the searching scope, in a reference image of the current block using a first filter to obtain up-sampled first reference blocks, obtaining, using the up-sampled first reference blocks, at least one candidate motion vector corresponding to the current block, performing up-sampling interpolations on second reference blocks, corresponding to the at least one candidate motion vector, in the reference image of the current block using a second filter to obtain up-sampled second reference blocks, combining the up-sampled second reference blocks to obtain a predicted value of the current block.

  • Method and device for generating a predicted value of an image using interpolation and motion vectors
    Patent number: 9906788
    Abstract: A method and device for generating a predicted value of image that are mostly used to generate a predicted value of a current block during image encoding or decoding. The method includes: determining a searching scope, wherein multiple motion vectors are included in the searching scope; performing up-sampling interpolations on first reference blocks, corresponding to the motion vector in the searching scope, in a reference image of the current block by using a first filter to obtain up-sampled first reference blocks; by using the up-sampled first reference blocks, obtaining at least one candidate motion vector corresponding to the current block; performing up-sampling interpolations on second reference blocks, corresponding to the at least one candidate motion vector, in the reference image of the current block by using a second filter to obtain up-sampled second reference blocks; combining the up-sampled second reference blocks to obtain a predicted value of the current block.
