METHOD AND APPARATUS FOR PERFORMING LOCAL TO GLOBAL MULTIFRAME ALIGNMENT TO CONSTRUCT MOSAIC IMAGES

摘要

A method and apparatus that determines the topology of a sequence of images and then globally aligns the images with respect to each image's neighboring images. The apparatus includes a topology determination module (302), a local coarse registration module (304), a local fine registration module (306), a global consistency module (308), and a color matching/blending module (310). To accurately render a mosaic image from a sequence of images the topology determination and global alignment process are iterated to progressively produce accurately aligned images. The apparatus efficiently and accurately combines a plurality of source images into seamless panoramic mosaic representation of a scene, of arbitrarily wide spatial and angular extent, regardless of the order of images acquisition.
