Yesterday and today, Barron and I worked on responding to referee on the USNO-B paper. We resubmitted. It was a pleasure to update the paper according to constructive referee comments. The paper is improved.
Barron and I discussed several other blind
astronomy image meta-data projects including: We have shown some success in determining the date at which an image was taken, using the USNO-B-tabulated proper motions of the stars in the image. We are writing that up. We believe we can also determine the bandpass of an image, using the brightness ranking of USNO-B stars of different colors.
In related news, Roweis, Yann LeCun (NYU), Barron, and I may start a new project to perform morphological classification of galaxies. Both of my readers will be stunned, because they know that I am adamantly against morphological classification! However, we have a very new idea, which is to build models of galaxies in three dimensions, and try to explain all galaxy image data with a small number of three-dimensional models plus Euler angles. That is, the project is to create a fundamentally three-dimensional generative model of all images of galaxies. That would be new, and not be subject to my usual wrath.
