    Hello. I'm a new guy here. Thanks in advance for those who could help me.
    My groupmates and I are having a design project which has the title "A Design to produce digital copy of electrocardiogram thermal printout"
    The plan is, to design a way to retrieve drawn out results from a thermal paper, specifically the ECG results, then turn it into a digital data, or at most, a signal that could be processed (pretty much like from track recordings like audacity, garageband)
    certain things should be considered like:
    1.) detection of grid (measurement of the wave itself)
    2.) Detection of plot

    we plan to use a hand scanner, or scanner to scan in the results

    the design is described basically this way:

    What algorithm could we do to retrieve the scanned results and plot out a signal

    I think you will need computer power for image processing. There are open libraries that can do that work for you. Try to ask at processing forum.
