We present a new motion representation and estimation scheme that leads to improved coding eeciency of block-based video coders like e.g. H.263. The proposed scheme is based on motion-compensated prediction from more than one reference frame. The reference pictures are warped versions of the previously decoded frame. AAne motion parameters are used as warping parameters approximating the motion...

The aim of this study was to further understand how the brain represents spatial information for shaping aiming movements to targets. Both behavioral and neurophysiological studies have shown that the brain represents spatial memory for reaching targets in an eye-fixed frame. To date, these studies have only shown how the brain stores and updates target locations for generating a single arm mov...

This paper focuses on three commonly used sensorless methods based on high-frequency signal injection; namely, the rotating sinusoidal injection in the stationary reference frame, the pulsating sinusoidal injection in the estimated synchronous reference frame, and the pulsating square wave injection in the estimated synchronous reference frame. Although these methods have found applications in ...

The latest HEVC video coding standard [1] has improved the coding performance by applying a number of innovative tools compared to its predecessor H.264/AVC [2][3] including a wider range of variable block size motion estimation (ME), motion compensation (MC), prediction, and transformation units. The use of multiple reference frames (MRFs) with variable block sizes typically provides better co...
