运动补偿预测方法和设备
摘要：
本发明实施例提供一种运动补偿预测方法和运动补偿预测装置。该运动补偿预测方法包括：确定当前像素点的初始参考像素点在参考图像中的位置，所述当前像素点位于所述当前图像的第一子图像内；当所述初始参考像素点位于所述参考图像中与所述第一子图像对应位置的第二子图像之外时，根据所述初始参考像素点的位置确定所述当前像素点的目标参考像素点在所述参考图像中的位置；根据所述目标参考像素点的像素值和/或所述目标参考像素点的临近像素点的像素值，确定所述当前像素点的像素值的预测值。本发明实施例能够提高运动补偿预测的准确性。
摘要（英）：

Embodiments of this application provide a motion-compensated prediction method and a motion-compensated prediction apparatus. The motion-compensated prediction method includes: determining a location that is of an initial reference pixel of a current pixel and that is in a reference image, where the current pixel is located in a first sub-image in the current image; when the initial reference pixel is located outside a second sub-image that is in the reference image and that is at a location corresponding to the first sub-image, determining, based on the location of the initial reference pixel, a location that is of a target reference pixel of the current pixel and that is in the reference image; and determining a prediction value of a pixel value of the current pixel based on a pixel value of the target reference pixel and/or a pixel value of a neighboring pixel of the target reference pixel. In the embodiments of this application, accuracy of motion-compensated prediction can be improved.
