動き補償処理方法、エンコーダ、デコーダ、記憶媒体
Document Type and Number:
Japanese Patent JP7381615
Kind Code:
B2
Abstract:
Processing methods for motion compensation, an encoder, a decoder, and a storage medium are provided. The method includes the following. Construct a search position constellation based on an initial motion vector (11), select at least one search position from the search position constellation based on a preset range coverage rule (12), and set at least one search position as a new motion vector, and perform motion compensation based on the new motion vector to obtain a prediction value of a coding unit (CU) (13). The preset range coverage rule is to scatter a preset number of search points in the N search directions for selection. Therefore, a problem of reduced coding efficiency due to that some of search step lengths are not selected can be avoided, and it can be ensured that motion conditions of most objects can be satisfied, so that motion information can be expressed more accurately.
