3D Texture Analysis of DESS images showed promising predictive
capability for the onset of Osteoarthritis occurring within three years. High
accuracy (86%) was achieved using Naïve Bayes classifier on selected textural
features from tibial cartilage.
Figure 2. Example of the
cartilage layers implemented in the 3D Texture Analysis. Blue dashed line
represents the thickness of the cartilage. L10, L50, L90 show the layer
heights, in which the cartilage was analyzed. SUM represents the full cartilage
thickness.

per each layer using Naïve Bayes
and selected tibial features.
