View ArticleGraph Based Spatial Position Mapping of Low-Grade Gliomas
AbstractLow-grade gliomas (WHO grade II) are diffusively infiltrative brain tumors arising from glial cells. Spatial classification that is usually based on cerebral lobes lacks accuracy and is far...

View ArticlePrior Knowledge, Random Walks and Human Skeletal Muscle Segmentation
AbstractIn this paper, we propose a novel approach for segmenting the skeletal muscles in MRI automatically. In order to deal with the absence of contrast between the different muscle classes, we...
View ArticleEstimating Shadows with the Bright Channel Cue
AbstractIn this paper, we introduce a simple but efficient cue for the extraction of shadows from a single color image, the bright channel cue. We discuss its limitations and offer two methods to...
View ArticleJoint Tumor Segmentation and Dense Deformable Registration of Brain MR Images
AbstractIn this paper we propose a novel graph-based concurrent registration and segmentation framework. Registration is modeled with a pairwise graphical model formulation that is modular with respect...

AbstractThe Random Walks (RW) algorithm is one of the most efficient and easy-to-use probabilistic segmentation methods. By combining contrast terms with prior terms, it provides accurate segmentations...
View ArticleMRF-Based Blind Image Deconvolution
AbstractThis paper proposes an optimization-based blind image deconvolution method. The proposed method relies on imposing a discrete MRF prior on the deconvolved image. The use of such a prior leads...
View ArticleModeling Shapes with Higher-Order Graphs: Methodology and Applications
AbstractExtrinsic factors such as object pose and camera parameters are a main source of shape variability and pose an obstacle to efficiently solving shape matching and inference. Most existing...
