  2. 16. Optimization of paediatric CT examinations - An approach to minimize absorbed dose to patients with regard to image quality and observer variability

    Author : Kerstin Ledenius; Göteborgs universitet; []
    Keywords : Computed Tomography; Paediatrics; Radiation Dosage; Computer Simulations; Nonparametric Statistics; Observer Variation; Radiographic Image Enhancement;

    Abstract : The absorbed dose to paediatric patients is important bearing in mind the increased risk of radiation-induced cancer due to exposure to X-rays at young ages. Questions have also been raised of whether a CT examination of the paediatric brain might lead to a reduction in cognitive function. READ MORE

  4. 17. Enhancement of Salient Image Regions for Visual Object Detection

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geodesic distance; graph spectral decomposition; video processing; visual attention; color contrast and distribution; propagation; salient region; figure-ground segmentation;

    Abstract : Salient object/region detection aims at finding interesting regions in images and videos, since such regions contain important information and easily attract human attention. The detected regions can be further used for more complicated computer vision applications such as object detection and recognition, image compression, content-based image editing, and image retrieval.

  5. 18. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

    Author : Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Abstract : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. READ MORE

  6. 19. Low Power Wireless Technologies for IIoT : Analysis and enhancement of communication delay, reliability and scalability

    Author : Raúl Rondón; Mikael Gidlund; Fortunato Santucci; Mittuniversitetet; []
    Keywords : ;

    Abstract : In recent years, the implementation of wireless communication systems in industrial environments has significantly increased. As a result, new applications such as Industrial Internet-of-Things (IIoT) have arisen, reshaping the future of industrial automation. READ MORE

  7. 20. Direction of Arrival Estimation and Localization of Multiple Speech Sources in Enclosed Environments

    Author : Mikael Swartling; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beamforming; Detection and classification; Speech enhancement; Source localization;

    Abstract : Speech communication is gaining in popularity in many different contexts as technology evolves. With the introduction of mobile electronic devices such as cell phones and laptops, and fixed electronic devices such as video and teleconferencing systems, more people are communicating which leads to an increasing demand for new services and better speech quality.
