Software to convert black-and-white image lines into digital data?

Hello. You need to convert the files of images (ECG, EEG, etc) to a file with the coordinates of the vertex points, or coordinates of the lines, or some other kind of data you can work with mathematically.

And where, if not secret, are the data?
If the equipment, then is it no regular export function into something digestible?
I assume that's a scan of the paper) - Brody_Dickins commented on July 8th 19 at 16:23
: Yes, no, if the picture is real - it is clearly not a scan in the screenshot. - Daphne_Roob commented on July 8th 19 at 16:26
A picture from the Internet
Equipment allows you to export only high-resolution images and PDF files.. - Rashad_Sporer commented on July 8th 19 at 16:29
: It may well be that the PDF will be vector. Try to open such a file some vector editor, Illustrator, Korel, or, at worst, Inkscape. - cortney.Kuhic commented on July 8th 19 at 16:32
And on the disc it does not store these files?
Perhaps their internal format, you can either find or it will be obvious and text. - Daphne_Roob commented on July 8th 19 at 16:35

Specific software under this deed are not met, I don't think it exists, but not much complexity to write no, leave on the strength of a couple of hours. Can help with this if you need, only need to specify what you need at the output.
I understand it would be ideal according to the chart to get an array of the height values of the chart (from -1 to +1), but the data will be cropped, because in some places visible overlay one chart on another.
Overlay is possible in the graphic editor to manually correct - Brody_Dickins commented on July 8th 19 at 16:25
It is possible, but I think more likely that not really need anything above a certain threshold just to cut the perfect precision, given that the picture is still limited in resolution. - Daphne_Roob commented on July 8th 19 at 16:28
then pour on github) - Rashad_Sporer commented on July 8th 19 at 16:31

The Matlab function findpeaks(x) (there is setting) find all local maxima. Accordingly, findpeaks(-x) lows.
What to recognize? You can also Matlab. But it is easier, as advised, to find a communication interface with the instrument.
