“…We often adopt different global motion model according to different applications, while the accuracy and computing complex are affected by the model. When pinhole camera model is used, and only rotation center projection and zoom are considered, we adopt plane perspective model with eight parameters [5]. But the affine model with six parameters will meet most applications to describe the linear transformation of global motion.…”

In this paper, a fast global motion estimation algorithm is proposed to speed up the processing of microscopic image sequence. A translation model based on non-linear density estimation is adopted by the proposed algorithm. To speed up the process, three-level pyramid is used. Noise detection and feature pixel extraction run simultaneously in each pyramid level. Then the motion parameters is estimated only with the feature pixels. The experimental results show that the computational complexity of the proposed algorithm is reduced much while estimation accuracy is maintained compared with the MPEG-4 algorithm.
