Dot annotation to segmentation mask #19

Open tand826 opened 4 years ago

current

Dot annotation does not give precise information for segmentation tasks because the precise contour information can not be single coordination.

add

Add function to guess the contour from a dot annotation. It might be a light-weighted NN or watershed-based method?

bnapora commented 4 years ago

Watershed-based methods have had some success, primary challenge is over-segementation. Use of a the dot annotation to define precise location to identify ROI should help with that.

Implementation could use a configurable square padding around the dot eg (90px x 90px) to identify the area the watershed function should be applied.
