Robust Estimation for Brain Tumor Segmentation

  title={Robust Estimation for Brain Tumor Segmentation},
  author={Marcel Prastawa and Elizabeth Bullitt and Sean Ho and Guido Gerig},
Given models for healthy brains, tumor segmentation can be seen as a process of detecting abnormalities or outliers that are present with certain image intensity and geometric properties. In this paper, we propose a method that segments brain tumor and edema in two stages. We first detect intensity outliers using robust estimation of the location and dispersion of the normal brain tissue intensity clusters. We then apply geometric and spatial constraints to the detected abnormalities or… CONTINUE READING
