TRACK 1: OBJECT DETECTION IN POOR VISIBILITY ENVIRONMENTS

TRACK 2: ACTION RECOGNITION FROM DARK VIDEOS

4th Workshop and Challenge on Learned Image Compression

image compression track

images need to be compressed to 0.075 bpp, 0.15 bpp, and 0.3 bpp (bits per pixel).

video compression track

short video clips need to be compressed to around 1 Mbit/s.
