From Local to Global Random Regression Forests: Exploring Anatomical Landmark Localization [link]Website  abstract   bibtex   
State of the art anatomical landmark localization algorithms pair local Random Forest (RF) detection with disambiguation of locally similar structures by including high level knowledge about relative landmark locations. In this work we pursue the question,how much high-level knowledge is needed in addition to a single landmark localization RF to implicitly model the global configuration of multiple,potentially ambiguous landmarks. We further propose a novel RF localization algorithm that distinguishes locally similar structures by automatically identifying them,exploring the back-projection of the response from accurate local RF predictions. In our experiments we show that this approach achieves competitive results in single and multi-landmark localization when applied to 2D hand radiographic and 3D teethMRI data sets. Additionally,when combined with a simple Markov Random Field model,we are able to outperform state of the art methods.
