Abstract: A method for fast multiple reference frame motion estimation, which is used to perform motion estimation between a current frame and reference frames Fn?1, Fn?2, . . . , Fn?k. The method performs a special block matching to find a plurality of motion vectors for blocks of each frame with respective to a previous frame and then composes motion vector(s) of the current frame referring to the reference frame Fn?(k?1) and a motion vector of the reference frame Fn?(k?1) referring to the reference frame Fn?k into composed motion vectors of the current frame referring to the reference frame Fn?k for the block in the current frame. The method selects a composed motion vector with a minimum of cost function from the composed motion vectors produced when composing the motion vectors and then finely adjusts the composed motion vector selected, thereby obtaining an adjusted motion vector.

Abstract: Methods and systems for fast variable block-size motion estimation based on merging and splitting procedures for AVC video encoding are disclosed. The methods take advantage of the correlation of the Motion Vectors (MVs) of the different block-size modes to achieve a good computation reduction. Considering that the smaller the block-size difference between two block-sizes is, the more correlations between their MVs can be expected, the methods use a 8*8 block as an initial processing block to calculate prediction MVs. The prediction MVs are then used in predicting MVs for other block-sizes.
