1. 1. Bildkomprimering med autoencoder och discrete cosine transform

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Martin Larsson; [2022]
   Nyckelord :compression; images; dct; machine learning; komprimering; bildanalys; dct; maskininlärning;

   Sammanfattning : Millions of pictures are captured each year for different purposes, making digital images an ubiquitous part of modern day life. This proliferation was made possible by image compression standards since these images need to be stored somewhere and somehow. LÄS MER

4. 3. Impact of Video Compression on the Performance of Object Detection Algorithms in Automotive Applications

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

   Författare :Kristian Kajak; [2020]
   Nyckelord :;

   Sammanfattning : The aim of this study is to generally expose the impact of using video compression methods on the performance accuracy of a neural network-based pedestrian detection system. Moreover, the emphasis is on investigating the consequences of using both compressed training and testing images with such neural network applications. LÄS MER

5. 4. Enhancing the JPEG Ghost Algorithm using Machine Learning

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Siddharth Rao Gondlyala; [2020]
   Nyckelord :JPEG Ghost; Splicing forgery; Localization; Image Processing; Machine Learning;

   Sammanfattning : Background: With the boom in the internet space and social media platforms, a large number of images are being shared. With this rise and advancements in technology, many image editing tools have made their way to giving rise to digital image manipulation. LÄS MER

7. 5. 3D Reconstruction of Small SolarSystem Bodies using Rendered and Compressed Images

   Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Gabriel Jörg Schwarzkopf; [2020]
   Nyckelord :deep space exploration; simulation; Small Solar System Bodies; compression; image rendering; computer vision;

   Sammanfattning : Synthetic image generation and reconstruction of Small Solar System Bodies and theinfluence of compression is becoming an important study topic because of the adventof small spacecraft in deep space missions. Most of these missions are fly-by scenarios,for example in the Comet Interceptor mission. LÄS MER
