We are ending the year with a big bang! Uddipan and Gopi's paper titled, Tweening Boundary Curves Of Non-Simple Immersions Of A Disk won the sole best paper award at ICVGIP 2012. A big congratulations to both

It is our great pride to report that the planar multi-projection display, which is currently the attention of a significant amount of research conducted in the iGravi lab, is part of the logo for the top international conference in virtual reality, IEEE Virtual Reality 2013. IEEE VR 2012 was hosted by the iGravi lab in March 2012. It was the most attended conference in the history of IEEE VR. As part of IEEE VR 2012, we had a very successful Open House at Calit2 showcasing all the research projects at iGravi where we also demonstrated this planar multi-projector display. Almost 450 people from around the globe attended the Open House.

We had two papers in Siggraph 2012 from UCI. This is the first time we have had papers in Siggraph from UCI. Our paper on new enhanced resolution projection based displays was one of the four papers in the sole session on Computational Displays -- a very new emerging area in computer graphics and visualilzation community. The other papers were from MIT, Stanford and UC-Berkeley. We are very proud to wrestle a spot amongst such well-know players. The second paper was a joint work with Purdue University and was in the Appearance section. The other papers were from Yale University, MIT, Microsoft Research and HP Labs.

Computer Science Professor Aditi Majumder and graduate student Behzad Sajadi will be presenting at the IEEE Visualization 2012 Conference.

The paper, entitled "Using Patterns to Encode Color Information in Dichromats," explores ways to use patterns to represent color.

This paper proposes a technique for using patterns to encode color information for individuals with CVD, in particular for dichromats.  Further, since overlaying patterns does not compromise the underlying original colors, it does not hamper the perception of normal trichromats.

IEEE VR 2012 is the premier international conference and exhibition on virtual reality.

You will find the brightest minds, the most innovative research, the leading companies and the most stimulation discussions in the fields of virtual environments, augmented reality, 3D user interfaces, all gathered in Orange County, California during March 4-8 (Sun-Thu), 2012. We invite you to submit your work, show your products and join us for a fascinating week of presentations, exhibits, workshops, tutorials and special events.

Once again, IEEE VR 2012 is pleased to be co-located with IEEE Symposium on 3D User Interfaces (March 4-5). In addition, this time we are co-locating ACM SIGGRAPH Symposium on Interactive 3D Graphics, 2012 with IEEE VR. ACM I3D will happen just following IEEE VR on March 9-11, 2012 at the same venue. We hope that the co-location of these two conferences with large overlapping domains and interest will bring forth new ways to support cross-fertilization of ideas.

IEEE VR, hosted by University of California, Irvine, will be held at the Westin South Coast Plaza, Costa Mesa in Orange County, CA. Orange County belongs to the greater Los Angeles (LA) area which is one of the biggest academic and IT centers of USA. UC-Irvine, UC-Los Angeles, University of Southern California, and Cal-State Fullerton are the main academic centers of the area. Los Angeles, Irvine, Westminister and other such towns of the area are the home of thousands of IT companies including gaming (e.g. Blizzard), entertainment (e.g. Disney, Dreamworks, Pixar, Institute for Creative Technologies), and devices (e.g. BenQ, Canon). With the co-location of IEEE 3DUI and ACM I3D, we will provide ample opportunities for cross-fertilization of ideas and technology across different synergistic communities centered around virtual reality.

Majumder

Aditi Majumder, Computer Science Associate Professor, was a keynote speaker at the International Symposium on Visual Computing 2010, a prestigious graphics and vision conference that brings together renowned researchers from all over the world.

Majumder’s talk, “Ubiquitous Displays: A Distributed Network of Active Displays,” presents her team’s work-in-progress on developing a new display paradigm in which displays are not mere carriers of information, but active members of the workspace — interacting with data, user, environment and other displays. The goal is to integrate such active displays seamlessly with the environment, making them ubiquitous to multiple users and data.

Majumder’s research aims to make multi-projector displays truly commodity products and easily accessible to the common man. Her significant research contributions include photometric and color registration across multi-projector displays, enabling use of imperfect projectors in tiled displays, and more recently a distributed framework for tiled displays via a distributed network of projector-camera pairs. A 2009 recipient of the NSF CAREER award, she has played a key role in developing the first curved screen multi-projector display being marketed by NEC/Alienware and is an advisor at Disney Imagineering for advances in their projection-based theme park rides.

Computer science professor Aditi Majumder has been awarded a Best Paper Award at the IEEE Workshop on Projector and Camera Systems (PROCAMS) held at the IEEE Conference on Computer Vision and Pattern Recognition (CVPR) in San Francisco. Her paper entitled, "Display Gamut Reshaping for Color Emulation and Balancing" was coauthored by researchers at Ostendo Technologies Ltd.

Majumder et al present a hardware-assisted 3D gamut reshaping method that handles a gamut expansion in LED based DLP displays in emerging mobile digital light projectors (known commonly as pico-projectors). These projectors use multiple LED/laser sources instead of a singular white lamp providing a larger color gamut. The full abstract and paper can be found here [PDF link].

The IEEE CVPR Workshop on PROCAMS is one of the top international venues for projector-camera systems researchers and practitioners.

Majumder's research addresses novel projection based displays and methodologies to register and interact with them - an important problem to both the scientific and entertainment fields. Majumder has developed a suite of mathematical models, methods and software to register and interact with large tiled projection based displays.

Behzad Sajadi

Computer Science Professor Aditi Majumder and graduate student Behzad Sajadi have received the Best Paper Award at the IEEE Virtual Reality 2010 conference held in Boston.

The paper, entitled "Auto-Calibration of Cylindrical Multi-Projector Systems," explores registering multiple projectors on vertically extruded a cylindrical display, which previously was only possible with a calibrated stereo camera.

This papers shows that using some simple priors, one can achieve multiple projector registration on a cylindrical display using a single uncalibrated camera without any markers on the display. More importantly, the new method enables use of multiple overlapped projectors across corners of a vertically extruded surface with sharp edges. This is of tremendous benefit to virtual reality display systems like CAVEs, that avoided mounting projectors across the corners until today.

A paper entitled, "Markerless View-Independent Registration of Multiple Distorted Projectors on Extruded Surfaces Using an Uncalibrated Camera" by Computer Science professor Aditi Majumder and graduate student Behzad Sajadi has won the runner up in the Best Paper Award at the IEEE Visualization 2009 conference held in Atlantic City this month.

The paper presents the first algorithm to geometrically register multiple projectors in a view-independent manner on a common type of curved surface, vertically extruded surface, using an uncalibrated camera without attaching any obtrusive markers to the display screen. This simple markerless registration has the potential to have a large impact on easy set-up and maintenance of large curved multi-projector displays, common for visualization, edutainment, training and simulation applications.

IEEE Visualization is the premier annual forum for visualization advances for academia, government, and industry. This event brings together researchers and practitioners with a shared interest in visualization tools, techniques, and technology.
