An image mosaic method based on improving seam line

In the traditional image mosaic algorithm based on seam line, the line is searched by making the color and neighborhood structure difference as small as possible in the overlap region of the images. However, when a small object with single color and symmetrical structure appears, the color and the neighborhood structure difference are not able to restrain the direction of the seam line. The appearance of the seam line crossing the object leads to the deformity of the crossed object in the mosaic image. Aiming at this problem, the image contour energy based on the above two parts is proposed to punish seam line in this paper, which can change the direction of seam line. Experimental results show that the new energy formula used in this paper can effectively avoid the crossing and the deformity.
