I have an image of terrain that has presumably had an embossed effect applied (exact technique unknown) and I would like to convert that image into a grayscale depth/displacement map (ie. Digital Elevation Model), effectively un-embossing the image. How would I do that? Are there any tools/libraries that might help me?Example of embossed input imageExample of desired output (from a different input)
