Dear participants,

  1. So far we received submissions from 7 teams. 4/7 submissions were successful.
  2. 3/7 teams faced issues with a few slides in the test set.
  • The issue arises either from Open Slide library (not sure about the particular version) : openslide.lowlevel.OpenSlideError: Corrupt JPEG data: premature end of data segment
  • The issue also arises from tiffile (not sure about the particular version): imagecodecs._imcd.ImcdError: imcd_lzw_decode returned IMCD_LZW_CORRUPT or imagecodecs._jpeg8.Jpeg8Error: Unsupported marker type 0x8b

We did not face these issues with our baseline: https://github.com/DIAGNijmegen/LEOPARD-challenge-baseline, which uses whole-slide-data with ASAP backend.

We will work with participants whose algorithms failed to find out the solution. In case this issue will not be resolved before the deadline, we might need to extend it / run the evaluation locally.

Kind regards, Khrystyna
