Temporal interpolation of video sequences using zonal based algorithms
Temporal interpolation has been recently proposed as a solution for increasing temporal resolution or even for predicting missing or corrupted frames within a video sequence. In t...

Motion Estimation with Incomplete Information Using Omni-Directional Vision
We present a new motion estimation framework and apply it to omni-directional imagery. Our method estimates motions incrementally using an Implicit Extended Kalman Filter (IEKF). ...
