Transform-domain temporal prediction in video coding: Exploiting correlation variation across coefficients
Temporal prediction in standard video coding is performed in the spatial domain, where each pixel is predicted from a motioncompensated reconstructed pixel in a prior frame. This ...

Real-Time Estimation of Dominant Motion in Underwater Video Images for Dynamic Positioning
In this paper, we propose a 2D visual motion estimation method which can be exploited to achieve a dynamic positioning (eg. by gaze control) with respect to a sea-bottom area of i...
