1. 1. Fiat Lux : En undersökning om användningen av projection mapping i projektionskonst

   Kandidat-uppsats, Högskolan Dalarna/Institutionen för kultur och samhälle

   Författare :Kristina Edlund; [2023]
   Nyckelord :Projection mapping; video mapping; spatial augmented reality; SAR; augmented reality; AR;

   Sammanfattning : Projection mapping är en teknik som används vid projektionsinstallationer. Denna uppsats undersöker teknikens påverkan på upplevelsen av en installation på en tredimensionell arkitektur. LÄS MER

3. 2. Coverage Motion Planning for Search and Rescue Missions : A Costmap Based Approach for fixed wing UAVs using Simulated Annealing &Cubic Splines

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Författare :Fredrik Rönnkvist; [2023]
   Nyckelord :Motion planning; Path planning; Cubic splines; Coverage path planning.;

   Sammanfattning : The present study proposes a novel approach to Coverage Path Planning for unmanned aerial vehicle (UAV) inspired by the Orienteering Problem. The main goal is to develop an algorithm suitable for Search and Rescue Missions, which can produce a search pattern with dynamical constrains, that is not limited to the traditional back-and-forth motion or spiral patterns.

   Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

5. 4. Towards topology-aware Variational Auto-Encoders : from InvMap-VAE to Witness Simplicial VAE

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Aniss Aiman Medbouhi; [2022]
   Nyckelord :Variational Auto-Encoder; Nonlinear dimensionality reduction; Generative model; Inverse projection; Computational topology; Algorithmic topology; Topological Data Analysis; Data visualisation; Unsupervised representation learning; Topological machine learning; Betti number; Simplicial complex; Witness complex; Simplicial map; Simplicial regularization.; Variations autokodare; Ickelinjär dimensionalitetsreducering; Generativ modell; Invers projektion; Beräkningstopologi; Algoritmisk topologi; Topologisk Data Analys; Datavisualisering; Oövervakat representationsinlärning; Topologisk maskininlärning; Betti-nummer; Simplicielt komplex; Vittneskomplex; Simpliciel avbildning; Simpliciel regularisering.;

   Sammanfattning : Variational Auto-Encoders (VAEs) are one of the most famous deep generative models. After showing that standard VAEs may not preserve the topology, that is the shape of the data, between the input and the latent space, we tried to modify them so that the topology is preserved.

7. 5. Neural Networks for Material Decomposition in Photon-Counting Spectral CT

   Uppsats för yrkesexamina på avancerad nivå, KTH/Medicinteknik och hälsosystem

   Författare :Hugo Charrier; [2022]
   Nyckelord :PCCT; X-ray; scanner; photon counting; AI; neural networks;

   Sammanfattning : Photon counting computed tomography scanners constitute a major improvement of the field of computed tomography, opening various prospective and enabling the decomposition of computed tomography images into different materials. The material decomposition algorithm, mapping photon counts to material pathlengths, relies on a forward model with Poisson statistics. LÄS MER
