Image packages
Case A (Synthetic)
Total size of the images are 550MB.
Followings are the list of the images (HTTP download).
All images for A1 series (174MB)
All images for A2 series (193MB)
All images for A3 series (174MB)
All images for A4 series (10MB)
Files are compressed by ZIP.
Case A has correct vector information because of synthetic image. If you need the correct vector information, please contact organizer by e-mail.

Case B (Synthetic)
Total size of the images are about 37MB.
Followings are the list of the images (HTTP download).
ALL IMAGES (37MB)
Files are compressed by ZIP. The file contains 120 images.
Case B has correct vector information because of synthetic image. If you need the correct vector information, please contact organizer by e-mail.

Case C (Experimental)
Total size of the images are about 37MB.
Followings are the list of the images (HTTP download).
ALL IMAGES (37MB)
Files are compressed by ZIP. The file contains 100 image pairs.
Case C does not have correct vector information. The high-speed camera runs under 10,000fps with frame straddling of 10 micro-s time interval.
So each pair has 10 micro-s time interval, and time interval between 001a and 002a is 200 micro-s.
