Abstract
A motion estimation method and apparatus, and a non-transitory computer-readable storage medium are provided. In the method, for a predicting unit (PU) in a to-be-coded image, a candidate motion vector (MV) list for the PU is constructed based on advanced motion vector prediction (AMVP). A rate distortion (RD) cost value of each MV in the candidate MV list is calculated. A target MV of the AMVP corresponding to the smallest RD cost value of the AMVP is obtained. Integer motion estimation (IME) is performed on the PU based on a mapping point of the target MV of the AMVP in a reference frame. A target MV of the IME is obtained. The target MV of the IME is converted to quarter pixel precision, to obtain a reference target MV of quarter motion estimation (QME). Further, as a final result of a motion estimation process is determined.
