From: Radiomics analysis using MR imaging of subchondral bone for identification of knee osteoarthritis
Region delineation and trabecular bone segmentation. a Four regions of interests (ROIs) were segmented from knee joint MR images named medial femoral condyle (MF), lateral femoral condyle (LF), medial tibial plateau (MT) and lateral tibial plateau (LT). b Obtained trabecular bone segmentation at the lateral femur. From left to right: binarized using adaptive threshold; after the distance transformation; after moving redundant pixels, which was obtained by multiplying the second one with the morphological skeletons
