1. 1. Robust Visual Object Tracking mean shift, particle filters and point features

   Författare :Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

   Sammanfattning : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. LÄS MER

3. 2. Learning and Optimizing Camera Pose

   Författare :Lucas Brynte; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; structure-from-motion; camera pose estimation; machine learning;

   Sammanfattning : Plenty of computer vision applications involve assessing the position and orientation, i.e. the pose , of one or several cameras, including object pose estimation, visual  localization, and structure-from-motion. LÄS MER

4. 3. Imaging vision : functional mapping of intermediate visual processes in man

   Författare :Jonas Larsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The human visual system is highly adept at recognizing objects independent of changes in viewing conditions, such as viewpoint, illumination, and partial occlusions by other objects in the visual environment. This invariance to viewing conditions is believed to be achieved by generating invariant shape representations from the variable visual input. LÄS MER
