%X In order to give attention to both the smoothness of the boundary area near the seam and the coincidence of globe intensity in a resultant mosaic image simultaneously, an image mosaic method based on oriented vector field is proposed in this paper. With respect to the problem that it is very difficult for the existing image mosaic algorithms to be adaptive for the big gray difference between the to-be-mosaic images, an oriented vector field with the distributional characteristics of to-bemosaic object is set up at first. And then the resultant mosaic object is updated by interpolating and iterating under the guidance of the vector field. Finally, when the minimum gradient value near the seam is achieved, an ideal mosaic image with the effect of harmony in globe, and local smooth transition can be obtained. The experimental results demonstrate the effectiveness and adaptability of the presented algorithm in this paper.
