Structure-enhanced local phase filtering using L0 gradient minimization for efficient semiautomated knee magnetic resonance imaging segmentation

Abstract: The segmentation of bone surfaces from magnetic resonance imaging (MRI) data has applications in the quantitative measurement of knee osteoarthritis, surgery planning for patient-specific total knee arthroplasty, and its subsequent fabrication of artificial implants. However, due to the problems associated with MRI imaging, such as low contrast between bone and surrounding tissues, noise, bias fields, and the partial volume effect, segmentation of bone surfaces continues to be a challenging operation.

“…Slice-based evaluation of the performance of a DLM was conducted using four-fold cross validation to reflect the performance of a DLM in every slice 28 . The overall segmentation performance was calculated by averaging the performance of every slice 28 . Each voxel of the CBCT image was defined as true positive (TP), true negative (TN), false positive (FP) and false negative (FN) by comparing the prediction to the GT.…”
