Optical flow estimation on image sequences with differently exposed frames [PDF]

open access: yes, 2015
Optical flow (OF) methods are used to estimate dense motion information between consecutive frames in image sequences. In addition to the specific OF estimation method itself, the quality of the input image sequence is of crucial importance to the ...

Direct Optical-Flow-Aware Computational Framework for 3D Reconstruction

open access: yesIEEE Access, 2019
In this paper, a direct computational method is presented which combines optical flow and structure from motion (SfM) by putting the SfM problem in the framework of optical flow estimation. In other word, the optical flow is reparametrized in term of the
