1. Enhanced image analysis, a tool for precision metrology in the micro and macro world
Sammanfattning : The need for high speed and cost efficient inspection in manufacturing lineshas led to a vast usage of camera-based vision systems. The performance ofthese systems is sufficient to determine shape and size, but hardly to an accuracylevel comparable with traditional metrology tools. LÄS MER
2. Robust Real-Time Estimation of Region Displacements in Video Sequences
Sammanfattning : The possibility to use real-time computer vision in video sequences gives many opportunities for a system to interact with the environment. Possible ways for interaction are e.g. augmented reality like in the MATRIS project where the purpose is to add new objects into the video sequence, or surveillance where the purpose is to find abnormal events.

3. An Event-Reconstructing Silicon Detector for 1 µm Resolution Spectral Computed Tomography
Sammanfattning : Computed tomography (CT) is a medical imaging modality in which cross-sectional images of the human body are created using x-rays. Commercial CT scanners utilize energy-integrating detectors to measure the x-ray attenuation. However, photon-counting detectors with energy-discriminating abilities have started to emerge. LÄS MER
4. Preattentive gaze control for robot vision
Sammanfattning : A framework for a hierarchical approach to gaze control of a robot vision system is presented, and a implementation on a simulated robot is described. The robot is equipped with a heterogeneous sampled imaging system, a fovea, resembling the varying resolution in a human retina. LÄS MER
5. Fast Methods for Vascular Segmentation Based on Approximate Skeleton Detection
Sammanfattning : Modern medical imaging techniques have revolutionized health care over the last decades, providing clinicians with high-resolution 3D images of the inside of the patient's body without the need for invasive procedures. Detailed images of the vascular anatomy can be captured by angiography, providing a valuable source of information when deciding whether a vascular intervention is needed, for planning treatment, and for analyzing the success of therapy.
