(a,b) Two examples of OA cartilage reconstruction (sample size : \(512\, \upmu \hbox {m}\)\(*\, 512\, \upmu \hbox {m}\)) directly generated from confocal microscopy, respectively from MMT and MIA samples. Average wavelengths \(\lambda _x\) and \(\lambda _y\) for the whole study vary between 8 and \(28 \,\upmu \hbox {m}\). (c) Decomposition of the spatial frequencies of the gradients of the cartilage morphologies.
