At the middle level , the two candidates selected at the coarsest level and the other one based on spatial mv correlation at the finest level are used as center points for local searches , and a mv candidate is chosen for the next search level
在第1层，同样根据最小mse准则，选出一个运动矢量作为第0层的候选运动矢量。最终的初始运动矢量是在第0层，以所选出的候选运动矢量为中心获得。
Level numbers are ordered from 0 to 2 , and level 0 and level 2 represent the finest and coarsest level , respectively . the algorithm limits mv candidates to only three at the middle level , and describes the algorithm with three resolution levels . at the coarsest level , two mv candidates are obtained on the basis of minimum matching error for the next search level
根据序列图像的时间、空间上的相关性，将每帧图像依次按2 ： 1子抽样分成三层分辩率，从最粗糙的顶层(第2层)按最小mse准则选出两个运动矢量，再从最精细的底层(第0层)获得一个运动矢量，作为第1层的三个候选运动矢量集。
