I recently returned from ICCV 2009, where I presented a paper by Ariel Shamir, Shai Avidan and myself. The paper is titled ‘Mode-detection via Median-shift’ and deals with very fast clustering of large high-dimensional data sets. Our paper was part of the poster sessions, and it was the first time I’ve presented a poster at a vision conference. It was a very intense experience, over three hours of explaining and demonstrating our work to small groups of people. In the end I was completely exhausted but happy with the level of interest shown. In the project page you can download the paper and the poster, and hopefully soon some version of our software.
I’ve attended most of the sessions and overall I was impressed with the quality of papers presented. My two favorite papers were Super-resolution from a Single Image by Glasner, Bagon and Irani, and Building Rome in a Day by Agarwal et al.
Spring semester is ending (wiping sweat from brow) and summer is rolling around. And when I say rolling I mean rolling over me with its 35c and 100% humidity… excellent!
Its been a nice semester, I think both my courses went quite well. I was very pleased with the quality of work the students of my graphics course submitted (Examples here and here), and my Java students were also a nice bunch of people. Publication-wise I’m also quite happy. The paper I worked on with Shai Avidan at Adobe has been accepted to ICCV09 (Hurrah!). You can see the project page, it contains some interesting links in addition to the paper.
This summer I have two interesting projects to complete (all very hush hush of course), and lots of going to the beach with Shachar 
Well, I’ve returned from Eurographics where I presented ‘Image Appearance Exploration by Model-based Navigation’. The paper was well received and we got the 2nd best paper award. I’ve updated the project page with my Eurographics presentation and in the next few days I’ll update the demo application.
In other news, there’s a growing interest in my SDF (Shape-diameter function) work, so I created a project page here. This page links to the segmentation/skeletonization/part-retrieval application, and has the complete SDF bibliography.
A paper I wrote with Arik and Danny has been accepted to EG ’09. The paper is title ‘Image Appearance Exploration by Model Based Navigation’ and you can see the project page here.
The paper can be broadly categorized as an image processing paper, it deals with changing the appearance of an image by changing its colors. We tackle two major issues. The first one is how to model color changes in an image, and synthesize a new one with no (or little) artifacts. The second is how do we empower a user to make these changes? In most cases the user doesn’t have a well established desired outcome, and even if he does, getting there is a very tiresome trial and error process.
We model color changes using a Gaussian Mixture Model on the image’s colors, and present an innovative gallery based user interface which lets users explore through variations of an image, until they reach a desired result.
