About how to generater Normal_*.json about ncrf HOT 8 CLOSED

@ilikewind yes, for Normal_*.json files they were generated by random sampling coordinates from the normal tissue mask at some higher level, e.g. level 6.

from ncrf.

@yil8 I think the Normal_*.json should include all normal tissue, e.g. Normal_001.json represent the tissue area of Normal_001.tif. so I was confused about random sampling...
thanks.

from ncrf.

@ilikewind It's always impossible to enumerate all the tissue regions of a normal samples, so you have to do subsampling.

from ncrf.

@yil8 In order to check what Normal_.json are, I translate Normal_001.json to Normal_001.xml, so I can visualiize it. but it is obvious that normal_.json include all normal tissue. It is a intersting to use normal*.json than normal tissue mask images.

and I also want to know more detail you employ for the normal_.json generated. thank you .

@ilikewind I'm not quite sure how you generated this figure, it seems the blue dots are concentrated about boundary regions. This might due to the effect of hard negative mining.

from ncrf.

@yil8 the figure was generated by your file Normal-001.json at NCRF/jsons/train/.
And I am not sure if you mistake the json file for coordinates/normal_train.txt . It seems we are discuss different issues.
Best wish.

@ilikewind I am so sorry, I was completely wrong about your question, and indeed I confused between Normal_001.json with coordinates/normal_train.txt. Normal_001.json was not really used through out this code base. Honestly, I forgot how Normal_*.json were generated, but they were probably not generated base on tissue mask

@yil8 Ok, thanks for your patient. I will do something about it.
