The frontal eye field (FEF), in the prefrontal cortex, participates in the transformation of visual signals into saccade motor commands and in eye-head gaze control. The FEF is thought to show eye-fixed visual codes in head-restrained monkeys, but it is not known how it transforms these inputs into spatial codes for head-unrestrained gaze commands. Here, we tested if the FEF influences desired ...

Introduction: The H.264/AVC (Advanced Video Coding) codec has introduced multiple reference frames (MRF) for inter-prediction, in contrast to the single-reference frame of the earlier codecs such as H.263 version 1. In addition to the increased compression efficiency obtained by MRF, soon it was realised that MRF could also be used as a technique to prevent error propagation in video streaming ...

Long-term memory prediction extends motion compensation from the previous frame to several past frames with the result of increased coding efficiency. In this paper we demonstrate that combining long-term memory prediction with affine motion compensation leads to further coding gains. For that, various affine motion parameter sets are estimated between frames in the long-term memory buffer and ...

This paper presents a method for synthesizing novel views of moving objects in airborne video. The object of interest is tracked using an appearance based visual tracking method. The on-object point correspondence is then built and used to estimate the homography induced by the ground plane. With known camera focal length, the surface normal to the ground plane and the camera motion between two...

Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers. In this contribution, we consider an integrated GNSS navigation system to provide estimates of the position and attitude (orientation) of a 3D laser scanner...

sueyoshi and sekitani in 2007 presented a paper that explores the measurement of returns to scale under a possible occurrence of multiple solution in a reference set and a supporting hyperplane. the occurrence ofmultiple solutions is classified into type i and type ii. type i is an occurrence of multiple solutions in a reference set. type ii is an occurrence of multiple solutions on a supportin...

When a human or animal reaches out to grasp an object, the brain rapidly computes a pattern of muscular contractions that can acquire the target. This computation involves a reference frame transformation because the target's position is initially available only in a visual reference frame, yet the required control signal is a set of commands to the musculature. One of the core brain areas invo...
