Incorporating Differential Constraints in a 3D Reconstruction.. - Lengagne, Fua (Correct)
....large variations of the function to recover and tends to isotropically smooth the solution, no matter what the true variations of the function ought to be. This problem has been especially addressed in the case of image restoration [13] stereo reconstruction [12] optical flow computation [3], and motion estimation [1] These approaches, however, are image based whereas, given the task of reconstructing a surface from multiple images whose vantage points may be very different, we need a surface representation that can be used to generate images of the surface from arbitrary ....

....sur l estimation du flot optique. Cette problematique a fait l objet de multiples developpements dans la litterature. Les principales classes de methodes generiques ont ete appliquees en meteorologie, qu il s agisse de techniques de correlation [1] d approches variationnelles non parametriques [6] ou parametriques a support borne [12] ou d approches stochastiques dans un contexte markovien [4] Dans chaque cas, le recours a des methodes multigrilles (multiresolution, maillage adaptatif) permet la prise en compte de deformations de large amplitude. D autre part, la structure ....

Ces limitations sont levees en recourant a des modeles a points critiques multiples. L utilisation de polynomes d ordres superieurs a ete suggeree dans [6].

....affine transform and, therefore, it influences the computation of image gradients for moving object detection. Most of the approaches based on normal flow field rely first on warping the processed frame into the reference frame and then estimate a motion measure [31] 35] or the normal flow field [7] for detecting moving objects based on residual flow. In this paper, we propose incorporating the change in metric into the optical flow equation associated to the image sequence 27i (warped image) This allows us to derive the normal flow component which is based on the estimated affine ....
