Image Processing on LineA new way to publish?A new way to organize research in a lab?
Jérôme Darbon (UCLA and ENS Cachan), Nicolas Limare (ENS Cachan), Jean-Michel Morel (ENS Cachan)

Image Processing on Line: main goal
01/10/2009
Achieve « reproducible research » and therefore:
Allow EVERYBODY to try the algorithms on their own images (including deciderswho DO NOT program)Make all results of trials accessible in a Web archive (experiment sharing)Downloadable codeGive a list of examples AND counterexamples, and explain themDescribe the algorithms carefully (pseudocode+comments)Testing independent of any platform (no code download, no system requirement…)
This is particularly adapted to image processing!

The website of each algorithms shows and explains the failure cases. For instance for SIFT and ASIFT, failure comparing objects with night and day illumination

The online demo gives also access to the online archive. More than 1550 different images have been so far tried by on line users. They are grouped in pages of 50. Here are threeexamples tried by users, on a simple box, a building and a landscape.

Plans
-Make a substantial database of algorithms. New ones. But many classic ones
-Pass from atoms to molecules : . Stereo (calibration, stereorectification, matching, reconstruction. Image processing (noise, blur, color, contrast: requires reliable estimates)
-Official publication? . Needs a scientific AND technical committee
. Needs a union of labs to start (right now three labs volunteer)
. Needs to fix very carefully the rules for code description, examples, etc.
. Needs €€€€€ + $$$$$
