2. 1. Reinforcement Learning for Active Visual Perception

   Author : Aleksis Pirinen; Mathematical Imaging Group; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer vision; reinforcement learning; deep learning; active vision; object detection; human pose estimation; semantic segmentation;

   Abstract : Visual perception refers to automatically recognizing, detecting, or otherwise sensing the content of an image, video or scene. The most common contemporary approach to tackle a visual perception task is by training a deep neural network on a pre-existing dataset which provides examples of task success and failure, respectively.

4. 2. Investigations of neural attractor dynamics in human visual awareness

   Author : David N. Silverstein; Pawel Herman; Martin Ingvar; Karl Friston; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; attractor dynamics; visual awareness; visual perception; visual attention; attentional blink; backward masking; gliomas; brain tumor; white matter; cell assemblies; neocortical model; threat response; fear signaling; amygdala; Biological Physics; Biologisk fysik; Computer Science; Datalogi; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

   Abstract : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. READ MORE

5. 3. Interactive Perception : From Scenes to Objects

   Author : Niklas Bergström; Danica Kragic; Yiannis Aloimonos; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis builds on the observation that robots, like humans, do not have enough experience to handle all situations from the start. Therefore they need tools to cope with new situations, unknown scenes and unknown objects. In particular, this thesis addresses objects. READ MORE

6. 4. The perception of actions and interactions : And the importance of context

   Author : Joshua Juvrud; Gustaf Gredebäck; Denis Mareschal; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; action understanding; action perception; motion; perception; context; environment; eye-tracking; pupil dilation; Psychology; Psykologi;

   Abstract : The perception of actions and interactions is a dynamic process linked with perceptual processes, the internal and external states of the individual, prior experiences, and the immediate environment. Given these differential contexts, it is very likely there are differences in how infants perceive, interpret, and respond to actions. READ MORE

7. 5. Human response to wind turbine noise : perception, annoyance and moderating factors

   Author : Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; wind turbines; noise annoyance; sound perception; audio-visual interaction; low-level noise exposure;

   Abstract : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.
