I'm not familiar with image processing at all I have table that represent in logarithm and it's hard to extract accurate data from it I wonder it's possible to use image processing for reading the data??1

if you have matlab


if you Google plot data extraction software

you will likely find what you need

  • $\begingroup$ Hi! Any chance to elaborate on that? Having a link to the file which might disappear tomorrow is not enough. If you could describe the algorithm that is implemented then it would be great! $\endgroup$ – jojek Jun 11 '17 at 10:46
  • $\begingroup$ I checked and it's still there . It's been there for some time. The question was "if it was possible". Answer , "yes" based on link provided. Question was not "how to do it?" If I had to do it, I would pull the image into matlab and use ginput and eyeball some number of points on each curve. I would convert those points from pixel coordinates to plot coordinates and interpolate $\endgroup$ – Stanley Pawlukiewicz Jun 11 '17 at 18:59
  • $\begingroup$ Each of those steps can be automated to to some success for some effort. If I just need the numbers for just this plot. Problem solved. If I had to do this a lot. I'd spend more time. If I had something really good, I'd have a product. This was not what was asked. $\endgroup$ – Stanley Pawlukiewicz Jun 11 '17 at 19:05
