Title
Accurate Bone Segmentation in 2D Radiographs Using Fully Automatic Shape Model Matching Based On Regression-Voting
Abstract
Recent work has shown that using Random Forests (RFs) to vote for the optimal position of model feature points leads to robust and accurate shape model matching. This paper applies RF regression-voting as part of a fully automatic shape model matching (FASMM) system to three different radiograph segmentation problems: the proximal femur, the bones of the knee joint and the joints of the hand. We investigate why this approach works so well and demonstrate that the performance comes from a combination of three properties: (i) The integration of votes from multiple regions around the model point. (ii) The combination of multiple independent votes from each tree. (iii) The use of a coarse to fine strategy. We show that each property can improve performance, and that the best performance comes from using all three. We demonstrate that FASMM based on RF regression-voting generalises well across application areas, achieving state of the art performance in each of the three segmentation problems. This FASMM system provides an accurate and time-efficient way for the segmentation of bony structures in radiographs.
