Broadcast Engineering - April 2008 - (Page 20) TECHNOLOGY IN ACTION BEYOND THE HEADLINES This shows that the super-resolution framework includes all previously used techniques. An order zero interpolation is a simple copy of one pixel located before or after the missing pixel along the spatio-temporal direction. Line doubling and time weaving algorithms are Figure 3. Left: Motion adaptive algorithms compute a missing pixel with a spatial interpolation such copies respectively or a time interpolation from the previous and next pixels of same location. Right: Let It Wave’s along the vertical spatial super-resolution searches over a full space-time neighborhood for a directional interpolation that minimizes the resulting total variation. direction and along the time direction. A firstorder interpolation may be computed motion estimation errors. a specific choice.
