To extract the drawn features we need to cancel out noise and threshold the image pixel values.

[ ] A well lit environment would help tremendosly. I.e. an aparatus which ensures constant lighting conditions.
OpenCV offers thresholding capabilities:
adaptiveThresholding
globalThresholding with various methods. Needs investigation which one works the best.

In case lighting conditions are good and we use a thick black edding, simple global thresholding should work fine.

matthaeusheer commented 5 years ago

Needs hairline 0.05 thickness.

Done.
