  1. 1. Perceptual Surface Reconstruction

    Författare :Jens Månsson; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; system; kontroll; Psychology; Psykologi; numerisk analys; Datalogi; systems; control; numerical analysis; Surface; Contour; Depth; Vision; Binocular; Computer science;

    Sammanfattning : How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theoretical and computational perspective, as well as through empirical investigations. In paper one, the fundamentals of stereopsis are briefly reviewed, and the difficulties related with resolving the (stereo) correspondence problem are particularly discussed. LÄS MER

  3. 2. On massive weight loss and body contour

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Excess skin; överskottshud; obesitas; obesity; bariatric surgery; bariatrisk kirurgi; brösthypertrofi; breast hypertrophy;

    Sammanfattning : Abstract Background/Aims: Bariatric surgery is an effective treatment for severe obesity. However, massive weight loss is associated with adverse effects, such as excess skin. LÄS MER

  4. 3. Binding Three Kinds of Vision

    Författare :Leo Poom; Myron Braunstein; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Attribute-invariance; binding; contours; edge linking; gestalt-laws; illusory contour; lateral interactions; neuronal mechanisms; tilt effect; vision; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Pictorial cues, together with motion and stereoscopic depth fields, can be used for perception and constitute ‘three kinds’ of vision. Edges in images are important features and can be created in either of these attributes. LÄS MER

  7. 5. Towards Intelligent Deformable Models for Medical Image Analysis

    Författare :Ghassan Hamarneh; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.
