Geometric Probability

I found this GeomBlog post on geometric probability interesting.

Excellent Icon Site

If you've never seen Zefrank's strange graphical doohickeys... here.

Adobe offers standard raw camera format

Adobe announces a Digital Negative format (DNG). There's a serious tower of Babel going on with digital camera raw formats. At the same time, I'm sure Adobe would just love to own another standardized format (ala PDF and PostScript).

HDR Shop 2.0

HDR Shop 2.0 with feature list here: "Multi-threaded queuable architecture, JavaScript Scripting Interface, Batch Custom HDR Image Processing, Support for OpenEXR images, Load Raw images..."

Nividia's developer site has a wealth of information, some really great performance papers.

The Sony Computer Entertainment America research site also has some good stuff. Check out the stuff by Robin Green and Christer Ericson.

Apple's Core Image

Page on Apple's Core Image in the Tiger preview. A little more here at GPGPU

IMPaSTo - A Realistic, Interactive Model for Paint

Always interested in non-photorealistic rendering, natural media simulation, etc. Here's a link to IMPaSTo - A Realistic, Interactive Model for Paint presented at NPAR 2004 by Ming C. Lin.

The JPEG of Death

This is a bit old, but I'm posting it anyway. Just when you thought Microsoft had the security problem handled... et tu, JPEG?


Just noticed there's an official SIGGRAPH blog.


Picasa architect Michael Herf's Stereopsis site has a number of great little articles and graphic programming tips and tricks.

Ken Perlin

Master of eponymous noise, NYU's Ken Perlin's site is just plain fun. He showcases all sorts of little graphics experiments and doodads, many of which leverage his 3D renderer written in Java 1.

Adobe Releases Premiere Elements

An Elements version of Premiere.

Color Schemer Studio

Rendering Traditional Mosaics

An interesting 2003 paper on rendering traditional mosaics by image warping guru George Wolberg.

Aaron Hertzmann

Aaron Hertzmann always seems to be doing something interesting. Here's his research link.

The History of Alpha

Graphics pioneer Alvy Ray Smith has a number of classic CG papers and memos on his site.

Image Processing Fundamentals

If you're learning the image processing ropes, Young, Gerbands, van Vliet from Delft University of Technology have some good notes on Image Processing Fundamentals.

Distance Maps

Olivier Cuisenaire's site is a great source for everything you always wanted to know about distance maps but were afraid to ask. His PhD thesis, which deals with the subject comprehensively, is also available for download.


No new news. Just collecting links.

OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications.

OpenEXR is used by ILM on all motion pictures currently in production. The first movies to employ OpenEXR were Harry Potter and the Sorcerers Stone, Men in Black II, Gangs of New York, and Signs. Since then, OpenEXR has become ILM's main image file format.

Timo Jyrinki on HDR

Timo Jyrinki's 2003 HDR paper is nice overview of HDR processing and display.

Debevec HDR links

I wish I would have made it to SIGGRAPH 2004. Paul Debevec gave a course on HDR Imaging.

From Debevec's source page is a link to Greg Ward's page where he has a nice analysis of HDR file formats.

Also from Debevec's course page: Erik Reinhard who's into Photographic tone reproduction, Luminance matching, Iris rendering and other things. Also: Sumanta N Pattanaik who's into Realtime Realistic Image Synthesis and Rendering for Mixed and Augmented Reality.

The Mysterious Purple Fringe

Digital cameras have been producing strange artifacts in the form of a purple fringe in high contrast areas of digital photographs. Initially, a number of us assumed it was due to chromatic aberration, but further investigations put that theory into question. There are claims of chromatic aberration, blooming, interpolation problems. What is it?

Here are some links: 1 2 3

Microsoft--; Google++

Joe Beda of Microsoft's Avalon team leaves Microsoft for Google.

Frankly, I was disappointed with Ballmer's decision to cut benefits rather than people, as this sort of thing has a tendency to ripple through the industry and affect non-Microsoft employees (like me) as other companies follow Microsoft's suit.

If productivity per employee can't justify the benefits, perhaps that doesn't mean it's time to cut everyone's benefits--perhaps that means it's time to let some of the least productive employees go.

Three cheers to Google for its defiant commitment to its benefits program in its IPO statement. If I were Google, I'd consider doing Schumpeter proud by opening a Redmond office. There's probably a lot of intellectual fruit ripe for the picking in the hitherto well-tended Gatesian garden.

On a related note, if you can get to it, check out Howard Anderson's "Why big companies can't invent" in the April 30, MIT Tech Review.

Via Scobleizer , Larry Larson's art done with Art Rage from Ambient Design. Check out Hans Deconinck too.

Poisson Matting

Interesting post on Poisson Matting from one of the SIGGRAPH bloggers. Here's a link to the original Poisson Matting paper.

Graphics Bloggers?

There's a panoply of software development bloggers, but a serious dearth of graphics bloggers, it seems. I found this list of SIGGRAPH 2004 bloggers today.

High Dynamic Range Photography

In The Future of Digital Imaging - High Dynamic Range Photography, Jon Meyer raises some good points regarding digital photography and HDR, especially that with a wide enough dynamic range we can do away with flash and attendent problems such as red eye, the effects of artifical lighting, etc.

As far as cameras go, there's Spheron and the Leaf Valeo 22. It appears Kodak has published a research blurb on what they refer to as Extended Range Imaging Technology

Avalon release changed to 2006

Old news, now, but I'll note it.

"...At a meeting today with several hundred of the company’s top developer evangelists from around the world, Microsoft also announced that the Windows WinFX developer technologies, including the new presentation subsystem code-named "Avalon" and the new communication subsystem code-named Indigo, will be made available for Microsoft® Windows XP and Windows Server 2003 in 2006. This availability will expand the scope of opportunity for developers by enabling them to write applications that can run on hundreds of millions of PCs, resulting in enhanced experiences for users of those operating systems..."


The socks are the same. I go by thickness.
