Title: MOTION COMPENSATION PREDICTION METHOD AND DEVICE
Abstract:
Embodiments of the present invention provide a motion compensation prediction method and a motion compensation prediction apparatus. The motion compensation prediction method comprises: determining a position of an initial reference pixel of a current pixel in a reference image, the current pixel being located in a first sub-image of the current image; when the initial reference pixel is located outside a second sub-image at a position corresponding to the first sub-image in the reference image, determining a position of a target reference pixel of the current pixel in the reference image according to the position of the initial reference pixel; and determining a predicted value of a pixel value of the current pixel according to a pixel value of the target reference pixel and/or a pixel value of an adjacent pixel of the target reference pixel. The embodiments of the present invention can improve the accuracy of motion compensation prediction.
