    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.

  4. 4. Sar Remote Sensing of Sea Ice: Towards automatic extraction of geophysical information

    Detta är en avhandling från Department of Applied Electronics, Lund University

    Författare :Yan Sun; [1995]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; deformation; SAR; segmentation; cross-correlation; rotation; optical flow; motion detection;

    Sammanfattning : Synthetic Aperture Radar (SAR) images from the ERS-1 satellite have great potential for sea ice remote sensing due to its independence of daylight and clouds. The very high data rate of SAR (over 100 million bits per second) results in an enormous volume of data that threatens the ability of human interpreters. LÄS MER

  5. 5. White Layer Formation during Hard Turning of Through-Hardened Martensitic and Bainitic AISI 52100 Steel

    Detta är en avhandling från Department of Applied Electronics, Lund University

    Författare :Seyed Hosseini; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layers; residual stresses; phase transformation; dynamic recovery; bainite; dynamic recrystallization; carbide deformation; retained austenite; steel; martensite;

    Sammanfattning : Increased demands for flexible manufacturing lines, shorter cycle times and reduced impact on the environment drives the need for optimization of today’s manufacturing. For machining of hardened steel parts (>45 HRC), grinding has been the obvious choice for many decades. However, hard turning has often been considered as a replacement due to e. LÄS MER
