Fast variable-size block motion estimation using merging procedure with an adaptive threshold
2003
2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698)
A merging procedure for variable-size block motion estimation is proposed to reduce the computation for block-size decision. A smaller block-size is initially used for motion estimation. An adaptive threshold, which depends on the information obtained from the motion estimation, quantization parameter, and rate distortion cost function is used to determine if the motion vectors of the neighboring blocks should be merged or not. We simulate the proposed merging procedure using an H.264 video
