另一个3D显示装置-The orb

2010年1月29日 没有评论

在Ted上看到的,是2007年的视频,有点旧了,但仍然值得一看。

在此之后the Orb进一步发展,有了下面这个

This second iteration of the spherical surface display ORB debuted in April 2008 at the Coachella Valley Music and Arts Festival in Indio, CA. It features 216 lines of resolution on an 18″ (45cm) diameter sphere. Thanks to improved control, color depth is continually being advanced and currently stands at 343 colors. SD cards are used for storage, so as much as several hours of video can be programmed onto the piece, making it an ongoing experiment in terms of content.

18000000000(18G)像素的布拉格

2010年1月29日 2 条评论

疯狂的全景拼接。

最终的合成图有18G的像素!请试试能放大到什么程度。 摄影师用的摄影器材是canon 5D mark2,和一个焦距设在200mm的70-200mm的镜头,还有一个用来精确旋转相机的机械装置。拼接软件是PTGUI(收费软件),后期处理用的photoshop。原始数据有40G的像素,最终的合成图有18G的像素。所用的电脑配置是,8G的内存,单核3G至强处理器,windows系统。

摄影师花了一周来拼接,三周来完成最后的后期处理。 最终的photoshop文件(PSB)有120G比特,大的甚至不能保存成单一的tif或者jpeg。

来源是360cities,这也是个web2.0的网站,提供世界范围内各地全景图。可以找到东方明珠哦

转帖 将图像转换成音乐

2010年1月28日 2 条评论

来自小众软件

RGB MusicLab 可以把图片转换音乐,它自带了一张蒙娜丽莎的微笑,左边是马赛克后的蒙娜丽莎。设置好各种参数之后,点击 Create RGB music 之后,软件会生成一段音乐,并调用 Apple QuickTime 播放,所以需要安装 Apple QuickTime。该软件还有 mac 版本,请到官方网站下载

软件的原理就是把图像马赛克之后,把图片的颜色分成 RBG 三个值,并对应不同的乐器(有很多乐器可以选择)和节奏,你可以在软件的左下角设置它们。

赶紧去听听自己长啥样吧。还可以保存下来,当作手机铃声。这可是世界上独一无二的铃声。

ARE2010 和 ISMAR2010

2010年1月27日 1 条评论

2010年增强视觉领域最值得期待的两个会议:ARE2010 ISMAR2010.

ARE2010是关注商业应用的。日期是2010年六月二号。地点加州圣克拉拉。

Event (ARE), the first global event dedicated to advancing the business of , announced today that the inaugural event will be held at Santa Clara Convention Center, June 2-3, 2010.

ISMAR2010是学术圈的。日期是2010年十月三号。地点韩国首尔。期待markerless tracking和3D tracking的最新进展。

  • Mixed Reality (MR) and Augmented Reality (AR) allow the creation of fascinating new types of user interfaces, and are beginning to show significant impact on industry and society. The field is highly interdisciplinary, bringing together signal processing, computer vision, computer graphics, user interfaces, human factors, wearable computing, mobile computing, computer networks, displays, sensors, to name just some of the most important influences. MR/AR concepts are applicable to a wide range of applications. Since 1998, ISMAR and its forerunner events, IWAR/ISAR and ISMR, have been the premier forums in this vital field.
  • This year we are proud to present the 2010 IEEE International Symposium on Mixed and Augmented Reality (ISMAR 2010). The symposium will be held on Oct. 13-16, 2010 at COEX, in Seoul, Korea. We invite you all to participate in this great event for the exchange of new ideas in this exciting field!

3DDdisplay star wars 演示图像

啥也不说了,直接猛击进去看视频吧。眼泪哗哗的。一定要看啊。

The system works by projecting high-speed video onto a rapidly spinning mirror. As the mirror turns, it reflects a different and accurate image to each potential viewer. Our rendering algorithm can recreate both virtual and real scenes with correct occlusion, horizontal and vertical perspective, and shading.

增强现实之黑暗面

2010年1月25日 2 条评论

最近发生了一起很有趣的关于增强现实的争论。给大家分享一下。

起因是The Guardian的专栏作者Charlie Brooker的一篇关于增强现实的幻想。Charlie Brooker预言在技术成熟之后,人们就可以把街道上流浪汉统统过滤掉,换成一只只可爱的兔子什么的。换成有中国特色的说法就是,把不和谐的都和谐掉。这篇文章相当有趣特别是最后一部分,建议阅读一下。

Years ago, I had an idea for a futuristic pair of that visually transformed homeless people into lovable animated cartoon characters. Instead of being confronted by the conscience-pricking sight of an abandoned heroin addict shivering themselves to sleep in a shop doorway, the rich city-dweller wearing the would see Daffy Duck snoozing dreamily in a hammock. London would be transformed into something out of Who Framed Roger Rabbit.

这是个相当赛博朋克的预言,而且相当政治不正确(当然,这取决于你的幽默感–Augmented.org)。

Futurismic没有对预言中的倾向做过多评论,只是进一步发展了这个预言场景Futurismic把这个预言中的技术称为现实过滤器(),并凡是过滤器总是总是有漏洞的,到时候垃圾信息(Spam)就成了我们得以窥视现实的唯一通道。垃圾信息反到成了一线希望。很讽刺不是么?

As the first group works harder to filter out unwanted messages, the second works harder to break through. We see it in the arms race around advertising. We see it in politicians struggling to find new ways of reaching their audience. We see it in Google’s need to constantly change and update their pagerank algorithms as black hat SEOs learn to game the system.

So long as the arms race continues, the filters will get better without becoming perfect. And in those cracks, reality (or at least an alternate viewpoint) can intrude. Insofar as we believe that people can’t know in advance what is best for them or what information they should receive, we should celebrate inefficiencies in filters.

Augmented.org全面反击了Charlie Brooker的观点,首先Charlie Brooker所谈的技术在5-10年之内是不可能实现的,其次即使实现了,这也是一个双刃剑式的问题,没必要大惊小怪。

We are still in the early stages of AR, so let’s don’t do the second step before the first.

亲爱的读者,你的观点呢?

另:

九年前,我第一次听说赛博朋克,五年前,第一次读赛博朋克,想不到今天,我居然可以假装从事赛博朋克!HOLYSHIT!

Fraunhofer正在研发一个系统,可以用手机来看周围的电器消耗了多少能源。来源

The technology behind this feature is complex: A server stores pictures of the individual devices, taken from a number of directions. When the function is activated, the cell phone sends the picture taken to the server, which then compares the picture with the ones in its database. As soon as it has recognized the device, it determines the power consumption at the time as reported by the associated power plogg, and sends this information back to the cell phone.

神秘的mirascape

神秘的公司神秘的项目

Many of you have been wondering what exactly we have been working on at Neogence Enterprises and when we are going to launch something. We are planning on a full global launch in October, but we are going to release an open beta around June or July. Even more fun, we are going to release a very early alpha version in a few months. We have an aggressive plan for regular updates and iterations from alpha to full launch, and we want to involve the community. Grow with us.

Head on over to twitter and follow @ if you want to be on the list for early access and some early adopter specials. We aren’t planning on advertising this early alpha access beyond my blog here and a little bit of twitter. I’ll be interested in seeing how many people follow @mirascape (I am fascinated by social networks and the organics of viral word of mouth). We will start doing some announcements and updates on that twitter account once things are ready to open up access. Don’t expect frequent updates though, we are neck deep in development right now, and that has priority.

So, what is the Mirascape™?

Mira: Look! (Spanish), Wonderful or Astonishing (Latin), World (Russian), and Prosperous (Hindi).

The Mirascape™ is the world’s first global network, platform, and community. Mirascape™ is about connecting people, places, and things in a way never done before. It is about the convergence of social, local, mobile, and virtual. It is about empowering you, the user, to create and interact with media and the world around you in new ways. It is about engagement and experience.

公司介绍 4 :modiface

2010年1月23日 4 条评论

modiface 样例1

modiface是一家提供人像美化技术的公司,由多伦多大学的教授Parham Aarabi在2006年创建。modiface目前为20多家公司提供人像美化相关技术。

按照官网的说明,modiface提供人脸检测,五官定位,头发轮廓检测,发色变换,发型变化,face anit-aging,lifting alterations(这两个不会翻译,高手指点一下?),瘦身模拟和超过20种以上的人像美化,上妆效果。所有这一切都可以在几秒内完成,几乎不需要人工干预。

该公司的最大特点我觉得不是他们的技术,而是他们的运作方式。modiface不直接提供面向用户的服务,而是向其他公司提供核心技术。在这个计算机视觉这个仍旧很朝阳的领域里,人人都想着怎么发掘应用,这家公司有点意思,我不做应用了,我只做技术,你们爱怎么用怎么用吧。

基于计算机视觉的GUI测试

2010年1月22日 2 条评论

sikuli demo

设计GUI很痛苦,编写GUI代码更痛苦,修改GUI代码更更痛苦,测试GUI代码更更更痛苦,所以就有了这么个东西sikuli(死吧!苦力??),用计算机视觉进行自动GUI测试,以代替无比繁复的点击点击点击点击。

简单的说就是,测试人员编写测试脚本,计算机会自己去检查那个按钮,窗口,什么的到底出现没有。论文里有详细的解释,来自MIT CSAIL。

看起来是个不错的东西,不过作者也提到了,还有一些问题不能解决,比如现在sikuli虽然能检测某个按钮出现没有,但是如果其他地方莫名其妙出现个一个别的什么什么东西,sikuli是无能为力的,因为sikuli只知道到脚本指定的地方去检查,它还没有全屏“自省”的能力。
