Dot annotation to segmentation mask

[tand826]

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?

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.
