Powershell script to activate HDR in Windows 10

问题 I've scoured the net for resources on this, to no avail. I cannot find the syntax to toggle HDR in Windows 10. As it currently stands, the GUI function for this is buried in a menu, and is a huge pain in the ass to turn on and off per application as needed. Ideally I'd like to see if there's an ability to specify per monitor, but given how wonky this implementation seems to be on Microsoft's part, just being able to activate it on my primary display would be enough. Thank in advance for your

问题 It's very convenient to load GLTF- model in aframe, but no case is found that contains envmap texture. I'd like to see that the official can provide the same case as three official. pmremGenerator.fromEquirectangular(texture) function is used to make gltf model produce real reflection effect https://threejs.org/examples/#webgl_loader_gltf https://threejs.org/examples/#webgl_materials_envmaps_hdr 回答1: One way would be creating a custom component, which will: wait until the model is loaded

论文阅读笔记------A High Contrast Video Inverse Tone Mapping Operator for High Dynamic Range Applications

Mohammadi P, Pourazad M T, Nasiopoulos P. A High Contrast Video Inverse Tone Mapping Operator for High Dynamic Range Applications[C]//2019 IEEE International Symposium on Circuits and Systems (ISCAS). IEEE, 2019: 1-5. 摘要: 在这篇论文中,提出了一种高对比度的视频iTMO,它解决了现有方法的缺点,产生的HDR视频质量值得新兴的HDR技术的期望。 方法是内容自适应的,能够将SDR视频转换成任何目标动态范围的HDR视频。 方法遵循人类视觉系统(HVS)的特点,即对黑暗区域的亮度变化比明亮和正常区域更敏感,并相应地映射这些区域 。 提出的iTMO使用一种基于HVS对亮度变化敏感性的分割方法,并使用SDR框架感知编码的光值构建映射曲线,该iTMO基于每个SDR帧的亮度分布实现了高对比度的HDR视频。此外,我们的iTMO能够处理所有类型的SDR帧,从黑暗到明亮的场景,动态控制噪音和带状工件,保持它们在不可感知的水平。我们的实验结果表明,在最终的HDR视频的整体视觉质量方面,我们提出的iTMO平均优于现有的操作。 本文iTMO的工作流程如图1所示

HDR视频色调映射算法综述

摘要 色调映射是高动态范围(HDR)成像领域的关键组成部分。它的重要性体现在众多文献中都可以找到大量的色调映射方法,这是该领域二十多年积极发展的结果。尽管这些可以满足显示HDR图像的大多数要求,但随着HDR视频的出现,出现了新的挑战,这在色调映射运算符(TMO)的设计中需要更多的考虑。如今,存在许多支持视频资料的TMO。现在,由于标准显示设备的局限性,我们可以达到大多数摄像机捕获的HDR视频的高质量,而没有可见的瑕疵。 在本报告中,我们着手总结和分类到目前为止的色调映射研究,总结出色调再现管道的最重要趋势和特征。尽管这提供了对该区域的广泛概述,然后我们还是专门关注HDR视频的色调映射以及所面临的问题。首先,我们制定视频TMO需要解决的主要挑战。然后,我们提供每个现有视频TMO的描述和分类。最后,通过构造一组定量度量,我们评估了许多运算符的性能,以提示可以预期的渲染最少数量的瑕疵。这可以作为对HDR视频色调映射的最新技术的全面参考,分类和比较评估。 文章中对每一种TMO做了详细的描述,同时作者还提出了度量方法,来评价视频序列色调映射后的效果。对科学研究,实际应用都有很重要的指导意义。 Visual adaptation TMO,Interactive walk-through TMO,Time-adaptation TMO,Temporal exposure TMO Time

HDR显示器在 windows/PC 下正确的使用方式

安稳与你 提交于 2020-02-06 03:39:25
最近入手了一个HDR显示器,拿到手过后,发现对应使用HDR的教程实在是少之又少,很多windows用户都有HDR显示器,但大多数苦于无法正确使用,很有可能看到的HDR实则为转换后的SDR甚至是灰蒙蒙未调色的模式,最后导致HDR这个技术背锅,本帖主旨就是告诉大家在windows下,每个平台如何正确食用HDR。 因为我买的是显示器,没有入手HDR电视机,所以目前暂时只 整理了PC使用HDR 的方法,总共分为4个板块 1、游戏HDR 2、youtube HDR 3、netflix HDR 4、本地播放HDR 1、游戏HDR 大多数游戏不需要开启windows的HDR选项,游戏内设定即可激活HDR 游戏激活HDR也是最简单的。 顺便附上HDR支持游戏列表(已汉化)一览(截止2019年3月6日): 发行日期 游戏 开发者 发行商 2018年3月23日 星期五 A Way Out 逃离 Hazelight Studios Electronic Arts 2017年8月29日 星期二 ARK: Survival Evolved 方舟:生存进化 Studio Wildcard, Instinct Games, Efecto Studios, Virtual Basement, Abstraction Games Studio Wildcard 2017年8月15日 星期二 Agents of

Loading HDRi maps in Cocos3D

不问归期 提交于 2019-12-12 02:42:11
问题 I want to load an HDRi map (similar to Google Maps) in an iPhone application, and then I want to be able to load some 3D characters to play around in the scene. You can see here an example of what I would like to load: http://www.hdri-hub.com/hdrishop/freesamples/freehdri/item/117-hdr-041-path-free Currently I'm using Cocos3D for loading 3D models from Blender through POD export files, so maybe there is a way to load HDRi in Cocos3D. I found out this class CC3STBImage which can be used to

unity 拿到管线权限的解决方案

自己建个cmd 传给postprocess layer camera event可以加在这个cmd上控制位置 base pass post process ui都共享这段cmd 在一开始记下backbuffer hdr 不能在这个camera上关 这样unity内部关于hdr的开关就被关掉了 为camera建立一个代理 原本的main camera ui camer 的hdr关掉 代理 camera 开hdr用它画basepass mrt用 cmd.setbuffers rt ref 其实本质上就是加了个camera 画hdr画完换会原来的camera ///////////// 或者直接升级srp 尤其考虑到vulkan的subpass的封装 来源: https://www.cnblogs.com/minggoddess/p/10896754.html
