Hi,everyone
Can you tell me that after motion estiamtion, how can we do motion compensation to reduce energy at residual frame?
thanks in advance
 

once you find the motion vector while doing motion estimation, then motion compensation is done as follows: subtract the best matching block in reference frame to the target block in current frame to obtain the residual. this will be the motion compensated residual and contains significantly less energy, thus leading to better compression efficiency.
