Abstract
Systems and methods for generating a panoramic video from unstructured camera arrays. The systems and methods are configured to statically align corresponding image-frames of respective input video streams, warp the aligned image-frames according to a warping-order, and relax the warped image-frames thereby generating a temporally coherent panoramic video. Methods according to embodiments this invention utilize a new parallax-warping-error metric that is devised to capture structural differences created by parallax artifacts. The parallax-warping-error metric is effective in finding an optimal warping-order and in driving the warping process, resulting in a panoramic video with minimal parallax artifacts.
