Hello, I have an image of a fatigue crack that I want to analyse. It is simular to a photograph of the cross section of a (non-circular) tree showing the tree rings that indicate the growth of the tree. I would like to determine the spacing of the repeated growth patterns without actually picking off individual points (there are too many). Could someone give me an indication of how I could tackle this. It may be similar to a geographical mapping approach. Can anyone recommand any R packages that I should look at ?
