I have an old heatmap raster image and I would like to produce a new heatmap layer. Could this be done, taking as an input the old heatmap image instead of point values?

For example, suppose we have this image:

enter image description here

Can I create a new heatmap layer based on this image?

    Can you tell us anything else about the data you're working with? Do you know the location of the points that were used to produce it? This could be tough without knowing the original distribution of points and other factors like the smoothing bandwidth that was used for the KDE. – lambertj Aug 29 '18 at 15:36
