   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape modeling; deformable models; principal component analysis; echocardiography; snakes; active shape models; deformable spatio-temporal shape models; medial-based shape profiles; statistical shape variation; spatio-temporal shape analysis; magnetic resonance imaging; hierarchical regional principal component analysis; oral lesions; dynamic programming; segmentation; spring-mass model; shape deformation; optical flow; medical image analysis; artificial life; physics-based modeling; deformable organisms; digital color images; medial axis; active contour models;

   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.

5. 3. Automatic Shape Modelling with Applications in Medical Imaging

   Author : Anders Ericsson; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heart-infarction; lung-embolie; 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

6. 4. Pattern Recognition Methods for Oral Lesion Classification using Digital Color Images

   Author : Artur Chodorowski; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oral lesions; supervised classification; pattern recognition; computer-aided diagnosis; support vector machines; color; cancer; shape;

   Abstract : The present thesis addresses the development and application of pattern recognition methods for classification of oral lesions using digital color images as input. The human oral cavity is a site of numerous diseases and two of the common and visually similar lesions are oral leukoplakia and oral lichenoid reactions. READ MORE

7. 5. How hands shape the mind : The P400 as an index of manual actions and gesture perception

   Author : Marta Bakker; Gustaf Gredebäck; Amy Needham; Uppsala universitet; []
   Keywords : goal-directed actions; action processing; EEG; ERP; P400; gestures; grasping; embodiment; social development; give-me gesture; dynamic system theory; Psychology; Psykologi;

   Abstract : Being able to perform and understand actions is crucial for proper functioning in the social world. From birth, we use our bodies to act and to promote learning about ourselves, our environment and other people’s actions and intentions. Our mind is embodied; thus, our actions play a crucial role in cognitive and social development. READ MORE
