SIFT flow

Got SIFT flow working, producing Euclidean and FPLBP distances. Since we need to process lots of files in lots of configurations, I wrote a controller in Scala. Just kicked off a job to get ROC curve data for all easy conditions matched to pose-2 and easy otherwise. SIFT flow takes maybe 20s per image pair, so I'm going to pick it up again tomorrow.

face.com performance characterization and DB class

Spent today getting stuff in order so that face.com's performance on the Comcast MURI dataset can be systematically characterized. Most of the time went into building an HDF5 database storing a bunch of metadata for each image, including the face.com information. The data for the database was stored across a bunch of directories and file formats, so it took me a few attempts to get it constructed. Now that the database exists, I'm writing a script to automatically generate detection and miss examples by condition, including marking up the example image.

Also spent maybe 80min on db-class.org.
