Image Stitching Using Smoothly Planar Homography
It is an important but challenging issue to construct a reasonable seamless image mosaic from images with non-ignorable different viewpoints or multiple distinct planes.The main limitations of existing image-stitching approaches lie in two facts:(a)the multiple plane nature of scenes has not been well considered in the image alignment step,which usually results in obvious misalignments;(b)the ignored alignment errors often lead to broken structures in the seam composition step.To overcome these problems,this paper proposed a smoothly planar homography model for image stitching,by considering the multiplane geometry of natural scene.First,we integrate local warps estimated in each plane to achieve smoothly plane stitching.Then,we introduce a novel alignment-guided seam composition to handle parallax.Experimental results on a series of challenging data demonstrate that our model achieves the state-of-the-art stitching performance.
