Bi-Directional Motion Estimation For Motion Compensation In The Wavelet Domain

Öz

One of the main goals of video coding is to reduce the required bitrate to encode a video file to be transmitted or stored. Central to the video coding research is the concept of motion compensation, which has a required pre-processing step of motion estimation. Motion estimation methods used in video coding can be categorized into two groups employing either one (i.e. uni-directional) or two-directional (i.e. bi-directional) search algorithms. Although the uni-directional algorithms are faster than the bi-directional ones, the latter methods have the advantage of recovering objects affected by occlusion which in turn helps to increase the quality of reconstructed video sequences in the decoder side and to reduce the required bitrate to encode a video file. Therefore, our focus in this paper is to analyze the impact of a bi-directional wavelet-based motion estimation algorithm for motion compensation. The proposed method is performed in the wavelet domain using the relationship between wavelet subbands which decrease the computational cost of the search technique by reducing the size of the video frames with the wavelet decomposition. Experimental results demonstrate that the proposed technique outperforms both uni- and bi-directional motion estimation methods in reducing the required bits to be encoded both in spatial and wavelet domains.
