Furthermore, it doesn't consider the sort of view-dependent optimizations used to deliver 360 content, such as offset projections, saliency-based encoding, and content-dependent streaming. These techniques allocate resources to optimize parts of the frame where the viewer is most likely to look. ...
and also for tracking the assets184. The analytics engine190also supports predictive intelligence to provide predictions based on the analytics data192. The analytics engine190also stitches information tracked from various sources where the content is consumed and provides a holistic view, i.e.360degre...
###Deep 360 Pilot Learning a Deep Agent for Piloting through 360° Sports Videos 源码、数据集和视频演示 ego-centric(以自我为中心的) 背景: 看360°运动视频需要观察者连续选择视角,通过
Firstly, motion vectors are extracted from the video with a personalizedFFMPEGlibrary. Then the motion histogram is created based on the motion vectors of key frames. Each motion histogram represents one frame. Due to a lot of directions of motion (360o) which can display in a frame, 12 pos...
In this paper, we present our datasets of both content data (such as image saliency maps and motion maps derived from 360° videos) and sensor data (such as viewer head positions and orientations derived from HMD sensors). We put extra efforts to align the content and sensor data using ...
For example, the one or more image sensors 340 may be arranged to provide a panoramic view (e.g., a 360 degree panoramic view) of an area around a head-mounted display. For example, the one or more image sensors 340 may receive light through respective lenses (e.g., a fisheye lens...
* 摘要: 虚拟现实(VR)视频(通常以360美元$^\ Circ $视频形式)由于VR技术的快速开发以及消费级360 $^\ Circ $摄像机和显示器的显着普及而引起了人们的关注。因此,了解人们如何看待用户生成的VR视频,这些视频可能会受到混乱的真实扭曲,通常是在时空和时间上局部的。在本文中,我们建立了最大的360美元$^\ Circ ...
