    Abstract : Medical imaging continues to permeate the practice of medicine, but automated yet accurate segmentation and labeling of anatomical structures continues to be a major obstacle to computerized medical image analysis (MIA). Deformable models, with its profound roots in estimation theory, optimization, and physics-based dynamical systems, represent a powerful approach to the general problem of medical image segmentation.

    Abstract : Two important components of a visual recognition system are representation and model. Both involves the selection and learning of the features that are indicative for recognition and discarding those features that are uninformative. READ MORE

  4. 4. Automatic Shape Modelling with Applications in Medical Imaging

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Anders Ericsson; Lunds universitet.; Lund University.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung-embolie; heart-infarction; Parkinson; DaTSCAN; SPECT; SCINT; affine shape; MDL; automatic shape models; Deformable models; active shape; Mathematics; Matematik;

    Abstract : This thesis consists of two parts. The first part is devoted to automatic shape analysis and the second part is devoted to decision support systems in medical imaging. Shape models are widely used in segmentation and shape analysis. The thesis begins with a review of deformable models and the preliminaries of shape modelling. READ MORE

  5. 5. Adaptive Bounding Volume Hierarchies for Efficient Collision Queries

    University dissertation from Västerås : Mälardalen University

    Author : Thomas Larsson; Mälardalens högskola.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bounding volume hierarchies; Collision detection; Rigid bodies; Deformable models; Data structures; Simulation; Animation; Three-dimensional graphics and realism; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; Datavetenskap;

    Abstract : The need for efficient interference detection frequently arises in computer graphics, robotics, virtual prototyping, surgery simulation, computer games, and visualization. To prevent bodies passing directly through each other, the simulation system must be able to track touching or intersecting geometric primitives. READ MORE
