Recent advances in visual information retrieval
Web Search Interest for the term "CBIR"
According to Google Insights for Search, people is no longer interested in "CBIR" and/or "Image Retrieval" :)
Xyggy
Content-based image retrieval (CBIR) using ~1m flickr photos sourced from Cophir. Enter a query and Xyggy will find visually similar images based on their content. Improve relevance by dragging images in and out of the interactive Xyggy query box. Toggle images on and off from the search while looking. Go ahead and try it! Xyggy makes finding and searching an engaging and fun experience. Interact, explore and discover. Perfect for content search on media-rich sites and touch devices such as the iPod, iPad and Android. Content can include image, video and audio.

* How does the UI work?
- enter keywords/phrases and results will be displayed.
- drag one or more photos (one at a time) into query box to find other similar pictures
- drag images in AND out of the query box.
- toggle photos on and off while in the query box. useful while finding photos of interest.
- keywords/phrase can also be toggled on and off.
* Does the content-based image search work? Yes, and here are some examples:
a. sunflower
- results for query "sunflower": http://www.xyggy.com/image.php#&sunflower
- drag photo to find other similar ones: http://www.xyggy.com/image.php#128591463,&sunflower
- drag another picture: http://www.xyggy.com/image.php#128591463,194630700,&sunflower
b. sunflower + pendant
- results for query "sunflower": http://www.xyggy.com/image.php#&sunflower
- drag non-sunflower photo to find other similar ones: http://www.xyggy.com/image.php#147387916,&sunflower
* But, why don't many of the queries return meaningful results?
Because, there aren't any visually similar photos in the flickr image data set to match the query.
* The performance is slow?
The service runs on a hosted virtual server in the US.

I Hate Your Paper
Article from www.the-scientist.com/
Twenty years ago, David Kaplan of the Case Western Reserve University had a manuscript rejected, and with it came what he calls a “ridiculous” comment. “The comment was essentially that I should do an x-ray crystallography of the molecule before my study could be published,” he recalls, but the study was not about structure. The x-ray crystallography results, therefore, “had nothing to do with that,” he says. To him, the reviewer was making a completely unreasonable request to find an excuse to reject the paper.
Kaplan says these sorts of manuscript criticisms are a major problem with the current peer review system, particularly as it’s employed by higher-impact journals. Theoretically, peer review should “help [authors] make their manuscript better,” he says, but in reality, the cutthroat attitude that pervades the system results in ludicrous rejections for personal reasons—if the reviewer feels that the paper threatens his or her own research or contradicts his or her beliefs, for example—or simply for convenience, since top journals get too many submissions and it’s easier to just reject a paper than spend the time to improve it. Regardless of the motivation, the result is the same, and it’s a “problem,” Kaplan says, “that can very quickly become censorship.”
“It’s become adversarial,” agrees molecular biologist Keith Yamamoto of the University of California, San Francisco, who co-chaired the National Institutes of Health 2008 working group to revamp peer review at the agency. With the competition for shrinking funds and the ever-pervasive “publish or perish” mindset of science, “peer review has slipped into a situation in which reviewers seem to take the attitude that they are police, and if they find [a flaw in the paper], they can reject it from publication.”
“When it comes to journals and publications, I’m highly skeptical that [the peer review] process adds much value at all,” adds Richard Smith, former editor of theBritish Medical Journal, who has written extensively about peer review. “In fact, it detracts value because it wastes a lot of time of a lot of people,” he says. “There’s lots of evidence of the downside of peer review, and very limited evidence of the upside.”
Now, scientists and editors are taking alternative approaches to tackle some of the pervasive problems with traditional peer review and put the “scientific” back into scientific publishing. They include enabling authors to carry reviews from one journal to another, posting reviewer comments alongside the published paper, or running the traditional peer review process simultaneously with a public review.
“We thought that it’s time to change the atmosphere of how we communicate scientific knowledge,” says Idan Segev, a co-founder ofFrontiers, one of a handful of journals cropping up that aim to better this system that most consider essential to the scientific community.
