Why I downloaded 25331 images but not 25332?


I downloaded 25331 images but saw the instructions explaining there were 25332 images…

Does it mean I did wrong processing and deleted 1 image?


Hi @mwald,

Thanks for bringing this to our attention. You are right, there are only 25,331 images in the 2019 Training set. The instructions were inaccurate, but I’ve just corrected them.

To be totally clear, the ISIC_2019_Training_Input.zip bundle contains 25,333 files within:

  • 25,331 JPEG images
  • LICENSE.txt

Please let us know if you have any other questions.
