Recover experimental data from a heat map?

Nodata
Is there a R package (or something similar) available to recover experimental data from a heat map like the one shown here? Like the digitize package does for scatter plots...

I asked this question on BioStar too and people were kind enough to point out that ideally, I could just email the corresponding author and get the data. Ideally, the data would have been available from the supplementary information anyway. It is also pointed out that text-mining is inaccurate, and I would not know the units and/or transformations. Obviously, my bad for not adding these things in the question; they felt besides the point.

Well, I guess it is a win for science that people think Open Data is the norm already :)
