  1. 11. Industrial 3D Anomaly Detection and Localization Using Unsupervised Machine Learning

    University essay from Linköpings universitet/Datorseende

    Author : Kevin Bärudde; Marcus Gandal; [2023]
    Keywords : Machine Learning; 3D Anomaly Detection; Feature Extraction; Manufacturing; Computer Vision; Vision Transformer; PointNet;

    Abstract : Detecting defects in industrially manufactured products is crucial to ensure their safety and quality. This process can be both expensive and error-prone if done manually, making automated solutions desirable. READ MORE

  3. 12. Skattning av HGV och stamvolym med data från stereomatchade drönarbilder genom befintliga modeller från Skogliga grunddata

    University essay from SLU/Dept. of Forest Resource Management

    Author : Erik Forslöw; [2023]
    Keywords : drönare; stereofotogrammetri; skogliga grunddata; skogsbruksplanläggning;

    Abstract : Inom den svenska skogsbruksplanläggningen sker idag datainsamlingen traditionellt med subjektivt fördelade relaskopsytor. Den subjektiva mätningen varierar mellan och inom planläggare och har generellt ett relativt medelfel (rRMSE) på 9 % för grundytevägd medelhöjd (HGV) och 15–20 % for volym/ha. READ MORE

  4. 13. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tómas Halldórsson Alexander; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  5. 14. Anomaly Detection with Machine Learning using CLIP in a Video Surveillance Context

    University essay from Linköpings universitet/Datorseende

    Author : Christoffer Gärdin; [2023]
    Keywords : Datorseende; maskininlärning; CLIP; anomalidetektion; videoövervakning;

    Abstract : This thesis explores the application of Contrastive Language-Image Pre-Training (CLIP), a vision-language model, in an automated video surveillance system for anomaly detection. The ability of CLIP to perform zero-shot learning, coupled with its robustness against minor image alterations due to its lack of reliance on pixel-level image analysis, makes it a suitable candidate for this application.

  6. 15. Using the James Webb Space Telescope to Find Carbon Dioxide on Ganymede

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

    Author : Olof Helgesson; Oscar Lundin; [2023]
    Keywords : ;

    Abstract : The aim of this bachelor's thesis is to search for CO₂ on Ganymede by studyingobservations taken by the James Webb Space Telescope and in doing so, create aprocessing pipeline for JWST data. The data is collected by JWST's Near InfraredSpectrograph instrument which is used for spectroscopy in the near infrared spectrum. READ MORE
