Abstract: Active contour model is one of the most useful tools to solve image segmentation task. It has been widely used in recent years. In this paper, some prior works are discussed and Earth Mover’s Distance（EMD） is introduced into statistical active contour model. Then a new statistical active contour model based on EMD is proposed. However, the proposed global strategy usually leads to local segmentation error. Therefore, a new global-local strategy which combines global and local scheme into EMD is raised. The proposed strategy not only extends the application of the proposed EMD model but also further improves the performance.

Key words: Earth Mover’s Distance（EMD）, global-local strategy, Bhattacharyya distance, mutual information model, statistical active contour model
