1. 1. Enhancement-basedSmall TargetDetection for InfraredImages

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Yang Hanqi; [2023]
   Keywords : Infrared Images; Small targets; Dilated Convolution; Infraröda bilder; Små mål; Dilaterad konvolution;

   Abstract : Infrared small target detection is widely used in fields such as military and security. UNet, which is a classical semantic segmentation method proposed in 2015, has shown excellent performance and robustness. However, U-Net suffers from the problem of losing small targets in deep layers after multiple down-sampling operations. READ MORE

3. 2. How spatial split-attention effects in multimedia relate to cognitive load and visuospatial capabilities

   University essay from Lunds universitet/Institutionen för psykologi

   Author : Alfred Norén; Daria Lindholm; [2022]
   Keywords : Cognitive load; multimedia learning; spatial contiguity principle; spatial split-attention; object-spatial imagery; visuospatial capabilities; OSIVQ; cognitive style; Social Sciences;

   Abstract : The present study investigated firstly how spatial split-attention conditions in multimedia affects cognitive load, and secondly how individual differences in objectspatial imagery styles may affect this interplay. To test this, we included both objective measures (response time) and subjective measures (self-reports) of extraneous cognitive load in four different multimedia learning trials with spatially integrated versus separated multimedia presentations.

4. 3. THE EFFECT OF DIFFERENT INSTUNCTIONS ON SPATIAL LEARNING IN A VIRTUAL ENVIROMENT

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Khonde Triphose; [2021]
   Keywords : virtual environment; silcton; spatial knowledge; human navigation; instructions ; gender; mental rotation test; SBSOD; virtuella miljöer; silcton; rumsligt minne; navigera; instruktion; kön; mental rotation test; SBSOD;

   Abstract : A desktop virtual reality environment of a campus area (called Silcton) was used to examine how instructing participants on performing exploration in an unfamiliar environment impacts the acquired spatial knowledge. Participants explored the Silcton virtual environment, after having received differing instructions on what to do. READ MORE

5. 4. A HOPE FOR STROKE REHABILITATION : EXPLORING THE REHATT MIXED REALITY APPLICATION

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Mattias Widengren; [2021]
   Keywords : mixed reality; virtual reality; spatial attention; spatial neglect; stroke; mixed reality; virtual reality; spatial uppmärksamhet; spatial neglekt; stroke;

   Abstract : Unilateral spatial neglect (USN) is a common disorder after stroke. An application especially developed for stroke rehabilitation, the RehAtt Mixed Reality (MR) intends to train cognitive and motor functions that are affected by USN, by the means of interactive 3D games played in mixed reality, through smart glasses.
