I found that labels provided in task 2 may overlap with each other. For example, a region marked as globules may also has the label pigmented network. Is this normal? This has been observed in several images. Could you please check whether there is something wrong?
Thanks for bringing up this case. It is possible for multiple dermoscopic attributes overlap within a region. So, you may consider each of the 5 attribute labels to be independent (though possibly correlated) non-exclusive properties to detect.
