More Siggraph Madness….Is anything real nowadays?….

Photography, Research, Video
More crazy image-enhanced video rendering papers from University of Washington being presented at Siggraph08. I just can't get enough of these new applications of combining crappy video and some still frames to produce eye popping results. Most of the experiments in this video were done using a standard video camera and a hi-res still camera. The results were combined, some secret sauce added and you end up with these killer results. I for one can't wait for editing packages to include some of these research topics as new features....Can you say UNREAL :-) Using Photographs to Enhance Videos of a Static Scene from pro on Vimeo.

Transcode and stream DV to mpeg4 via firewire using VLC and Ubuntu 8.04 (Hardy Heron)

Firewire, Linux, MP4, Transcoding, Ubuntu, Video, VLC
Well kids are you ready for todays lesson in transcoding DV video. So first you need a decent machine. I'm using a P4 2.4Ghz oldie that has Firewire on-board and am chewing up 50% CPU for NTSC encoding. Then you need to get Ubuntu 8.04 installed. Once that's done use the following command to install vlc (Video Lan Client):sudo apt-get install vlcThen either follow this guide or if you're using 8.04 (Hardy Heron) ONLY, use the following command to add Medibuntu to your repository sources.list:sudo wget http://www.medibuntu.org/sources.list.d/hardy.list -O /etc/apt/sources.list.d/medibuntu.listfollowed bysudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get updateto add the GPG key for Medibuntu Repository. You may be asked to accept this package even though it cannot be authenticated. This is normal; typing "Yes" means you trust…

Stream your Linux/Mac/Windows Desktop as video using VLC (Part II)

Linux, Macintosh, Opensource, OSX, Video, VLC, Windows
A lot of people seem to be having problems (issues) with the original way I had proposed here using command line. So, I figured I make it real simple and do a graphical tutorial with screen shots to boot :-). In this example we first deal with the server (running windows) at IP address 192.168.1.1, then we move to our client (Mac OSX) at IP address 192.168.1.2 and view the servers screen remotely through streaming video. So first on the server (remember 192.168.1.1 is the IP address): 1) Bring up VLC and select File/Open Capture Device (Ctrl-A). You should see this screen modify the bottom portion (Advanced Options), so it looks like this picture below. You can decrease screen-fps to 15 if you like to speed things up a bit.…

Stream your Linux/Windows/Mac Desktop as video using VLC

Apple, CLI, Darwin Streaming Server, Linux, Macintosh, Opensource, OSX, Video, VLC, Windows
A buddy of mine (thanks Mike) showed me this today. There is a input Access module in the newer versions of VLC (0.8.6+) called "screen" which makes this possible. To stream your desktop to another machine (ip address: 192.168.1.2 in this case) just use the following command in Linux (sorry command line only):vlc screen:// :screen-fps=30 :screen-caching=100 --sout '#transcode{vcodec=mp4v,vb=4096,acodec=mpga,ab=256,scale=1,width=1280,height=800}:rtp{dst=192.168.1.2,port=1234,access=udp,mux=ts}'or in Windows (slightly different syntax) use this command:vlc screen:// :screen-fps=30 :screen-caching=100 :sout=#transcode{vcodec=mp4v,vb=2048,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=rtp,mux=ts,dst=192.168.1.1:1234}}This is one massive command, so lets take a look at it in more detail:screen:// is our input module selection (if you just run vlc screen:// you'll see your own screen on the server inside vlc....kinda cool):screen-fps=30 specifies that we want to screengrab at 30 fps (from default 5 fps):screen-caching=100 sets the internal caching to 100ms (from default 300 ms)--sout is…

Cool Hand Tracking Video….

Computer Vision, Research, Video
Speaking of hand tracking, here is a video of a guy playing around with an unknown system (looks a bit like linux). Very cool demo and almost perfect tracking. Not sure if it's IR or not, you can see him in the corner of the screen, but can't quite tell how it's done. Anyways, I'm posting it since it's one of the better ones I've seen. From the description:A C++ computer vision application to emulate the mouse and the keyboard in any application using hand gestures and a low-cost webcam.
