Claim 4:
5. The method according to claim 4, wherein the determining a second loss term based on a difference between the object optical flow and the projected optical flow comprises: determining the second loss term according to the following equation:

regular=Σ∥{tilde over (F)}(ui,vi)t−Fobj(ui,vi)t∥

wherein regular represents the second loss term, (ui, vi)t represents a first pixel in a t-th frame corresponding to an i-th real point pit, {tilde over (F)}(ui, vi)t represents a projected optical flow of the first pixel (ui, vi)t, and Fobj(ui, vi)t represents an object optical flow of the first pixel (ui, vi)t.
