摘要：A fast block mode determining method for motion estimation, and an
apparatus thereof. A cost of motion estimation for an input image frame is predicted by
Kalman filtering, and one block mode is selected from a plurality of block modes. A cost for the motion estimation of the input image frame is calculated. The predicted cost and the calculated cost are compared with each other, and the block mode for performing the motion estimation is determined. In an H.264 moving picture encoding device, the operation load is reduced and time wasted for calculation is shortened, because it is not necessary to perform the motion estimation for all the block modes.
