Hi
I have some paper graphs and need to extract data in (x, y) format. I scan all graphs to convert them in *.png file format. My problem is extract data from *.png files.
I search and find some codes, but they ask me to click over graph line manually. I need a practical code to do that automatically.
I google about my problem and find a website which extract data automatically. I test website with attached "chart1.png" file and set parameters as "SetParameters.png". It works perfectly.
I'm looking for a solution in MATLAB to extract data from my *.png files. Please help me to solve my problem.
Thanks a lot
Mani

I am certain that there is no "practical" code that can handle all of the various cases automatically. Possibly there might be practical code for one particular kind of graph, especially if it is all generated by the same software.
