1. 1. Enhancement of Salient Image Regions for Visual Object Detection

   Författare :Keren Fu; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

   Författare :Keren Fu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

   Sammanfattning : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. LÄS MER

5. 4. Promised Soils : Senses of Place Among Yezidis in Dalarna and Sheikhan

   Författare :Maria Lindqvist; Lena Roos; Simon Sorgenfrei; Göran Larsson; Södertörns högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Yezidi; Yezidi cemetery; Dalarna; Borlänge; Zahmanê Êzîdîa Li Dalarna; Iraq; Iraqi Kurdistan; Sheikhan; Lalish; transfer of ritual; social memory; jema’iyye; Çarşema-sor; Wednesday ritual; berat; diaspora; funeral rituals; mortuary practices; Historical Studies; Historiska studier;

   Sammanfattning : This is an ethnographic study that focuses on Zahmanê Êzîdîa Li Dalarna, the Yezidi cemetery, in Borlänge. The Swedish town of Borlänge has one of the largest Yezidi diaspora communities in Western Europe; a majority emigrated from the Northern Iraqi region of Sheikhan during the 1990s and early 2000s.

7. 5. Near-Field Study of Multiple Interacting Jets : Confluent Jets

   Författare :Shahriar Ghahremanian; Bahram Moshfegh; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple interacting jets; confluent jets; axisymmetric round jet; Low Reynolds number jet; Particle Image Velocimetry PIV ; Laser Doppler Anemometry LDA ; Hot-Wire anemometry HWA ; RANS turbulence models; SST ? − ?; Low Reynolds ? − ?; Response Surface Method;

   Sammanfattning : This thesis deals with the near-field of confluent jets, which can be of interest in many engineering applications such as design of a ventilation supply device. The physical effect of interaction between multiple closely spaced jets is studied using experimental and numerical methods. LÄS MER
