How to extract numerical data from plot images automatically?

how can we automatically extract numerical data from plot images in MMA (.dat or .csv file)?

For the test image (two curves in one image), x=[0 40]; y=[0 1]

if we use e.g. "getdata-graph-digitizer"

we have to grab points by clicking on points. it take some times ...

Can we extract these data automatically ("AI") in MMA?

P.S. @Alexei Boulbitch I have used your MMA app (How to make a curve selectable from a scaned image and convert it to a list of coordinates), it does not support this kind of image.

Thanks a lot in advance!
