Hiding seams in high dynamic range panoramas

摘要

This poster presents a simple and efficient method for stitching sections of a high dynamic range (HDR) panorama, taking advantage of perception to minimize visible seams. Most approaches to panoramic stitching require exact or nearly exact overlay of the input images in order to produce a seamless blend. Most methods also require identical image exposures, and do not work in HDR. We overcome these limitations with an approach that is fast and memory-efficient, working on a scanline at a time within each overlapping rectangle. Input to the algorithm is a set of HDR images with correspondence points between each pair to be joined, one point pair per seam. These correspondence pairs may be selected manually, or generated automatically using a technique such as [Pollefeys & Van Gool 2002].
