Title: A Robust Estimating Algorithm Based on Layered Progressive Matching
Abstract: By analyzing the disadvantages of the keypoint-based image stitching,a new automatic image-stitching algorithm is proposed.An improved RANSAC algorithm is used for getting rid of influence of the bad points.In the problem of the parameter estimation,a layered progressive matching scheme and Mellion transformation are employed in the initial parameter estimation when orientation of the images is great.The above scheme also improved computing efficiency.Experimental image-stitching results are better satisfactory,better robustness and stronger sense of reality.It is high valuable in practice.
