  1. 1. Compression of Sequential Voxel Data for Sequence-based Animation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Filip Antonijevic; [2023-10-23]
    Keywords : voxel; octree; grid; compression; animation; spatiotemporal; sorting; reordering; DXT; HSV;

    Abstract : This thesis presents a method for lossy compression of voxel data in an animation sequence. Uncompressed voxel animation can become very memory intensive and therefore need a more efficient method to store and render such data. READ MORE

  3. 2. Robust visual SLAM with compressed image data : A study of ORB-SLAM3 performance under extreme image compression

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

    Author : Guangzhi Wang; [2023]
    Keywords : ORB-SLAM3; compression; image feature; localization accuracy; internal parameter; hybrid compressing; brightness enhancement; ORB-SLAM3; kompression; bildfunktion; lokaliseringsnoggrannhet; intern parameter; hybridkomprimering; ljusstyrkeförstärkning;

    Abstract : Offloading SLAM to the edge/cloud is now becoming an attractive option to greatly decrease device energy usage. The new SLAM solution involves compressing image data on the device before transmission, allowing a further decrease in the network bandwidth when performing SLAM at the edge/cloud. READ MORE

  4. 3. An Open-Source Autoencoder Compression Tool for High Energy Physics

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Axel Gallén; [2023]
    Keywords : Physics; Particle Physics; Analysis; Machine Learning; Neural Networks; Autoencoders; Data Compression; Lossy Compression; Baler; Physics and Astronomy;

    Abstract : A common problem across scientific fields and industries is data storage. This thesis presents an open-source lossy data compression tool with its foundation in Machine Learning - Baler. Baler has been used to compress High Energy Physics (HEP) data, and initial compression tests on Computational Fluid Dynamics (CFD) toy data have been performed. READ MORE

  5. 4. Saliency driven lossy image compression using machine learning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Sebastian Fällman; [2023]
    Keywords : machine learning; image compression;

    Abstract : Since the introduction of digital media for consumers in the 1990s, the amount of images used in everyday life has grown exponentially. All these images need to be stored and broadcasted from some storage device, which has been made possible with the use of image compression algorithms such as JPG. READ MORE

  6. 5. Comparison of lossy and lossless compression algorithms for time series data in the Internet of Vehicles

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Joseph Hughes; [2023]
    Keywords : Data compression; Lossy compression; Lossless compression; Time series; Internet of Vehicles;

    Abstract : As automotive development advances, connectivity features are continually added to vehicles that, in conjunction, form an Internet of Vehicles. For numerous reasons, it is vital for vehicle manufacturers to collect telemetry from their fleets. READ MORE
