Motion estimation method, electronic device, and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory communicatively connected with the at least one processor;
• wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to perform a method for motion estimation, wherein the method for motion estimation comprises:
• determining candidate search spaces and candidate search starting points based on a lookahead motion vector and a predicted search starting point of a current block;
• determining a target search starting point from the candidate search starting points and determining a target search space from the candidate search spaces;
• performing a search based on the target search starting point and the target search space to obtain an initial motion estimation result for the current block;
• obtaining a target motion estimation result for the current block based on the initial motion estimation result.

A non-transitory computer readable storage medium with computer instructions stored thereon, wherein the computer instructions are used for causing a method for motion estimation, wherein the method for motion estimation comprises:

• determining candidate search spaces and candidate search starting points based on a lookahead motion vector and a predicted search starting point of a current block;
• determining a target search starting point from the candidate search starting points and determining a target search space from the candidate search spaces;
• performing a search based on the target search starting point and the target search space to obtain an initial motion estimation result for the current block;
• obtaining a target motion estimation result for the current block based on the initial motion estimation result.
