Encoding Scratch and Scrape Features for Wear Modeling of Total Joint Replacements
Figure 2
((a), (b)) Diffused-light images of a femoral head displaying both scratch and scrape damages, captured from two orientation directions 30° apart circumferentially. (The black dot in the center of the images is from camera lens reflection. This refection required that multiple view directions be utilized.) ((c), (d)) Image-processed results displaying identified damage regions. The sectors outlined in black indicate areas analyzed for this particular image. The top of the femoral head was captured and analyzed in companion polar images.
