Morphable 3D-Mosaics: A Hybrid Framework for Photorealistic Walkthroughs of Large Natural Environments

(a) Image ${ℐ}_k$ along with computed optical flow vectors (blue segments) for all points marked white. (b) Image ${ℐ}_{k+1}$ along with matching points (also marked white) for all marked points of (a). A few epipolar lines are also shown. 10 scales $S{=\{\mathrm{1,0.9}}^{-1}{\mathrm{,}\dots \mathrm{,0.1}}^{-1}\}$ have been used during matching.
