Automatic panorama image mosaic and ghost eliminating

Ghost is an important problem in the process of image mosaic. It results from the inaccurate registration or the moving objects in the image. In order to get rid of the ghost coming from inaccurate registration effectively, phase correlation technique, median flow filter and improved RANSAC are used to improve the accuracy of local registration. Bundle adjustment is used to correct the accumulated errors caused by the concatenation of pairwise homographies and the disregarded multiple constraints between images. In this paper, we put forward a new blending method which searches the blending region dynamically to eliminate the ghost caused by moving objects. Experiments demonstrate our method effective.
