  1. 11. Efficient Recycling Of Non-Ferrous Materials Using Cross-Modal Knowledge Distillation

    University essay from Linköpings universitet/Datorseende

    Author : Sebastian Brundin; Adam Gräns; [2021]
    Keywords : Recycling; Ferrous; Non-Ferrous; Knowledge Distillation; Hallucinogenic; Hyperspectral; HSI ;

    Abstract : This thesis investigates the possibility of utilizing data from multiple modalities to enable an automated recycling system to separate ferrous from non-ferrous debris. The two methods sensor fusion and hallucinogenic sensor fusion were implemented in a four-step approach of deep CNNs. READ MORE

  3. 12. Pretraining a Neural Network for Hyperspectral Images Using Self-Supervised Contrastive Learning

    University essay from Linköpings universitet/Datorseende

    Author : Natalie Syrén Grönfelt; [2021]
    Keywords : computer vision; hyperspectral imaging; self-supervised learning; pretraining; contrastive learning; pretext task;

    Abstract : Hyperspectral imaging is an expanding topic within the field of computer vision, that uses images of high spectral granularity. Contrastive learning is a discrim- inative approach to self-supervised learning, a form of unsupervised learning where the network is trained using self-created pseudo-labels. READ MORE

  4. 13. Reconstruction of Hyperspectral Images Using Generative Adversarial Networks

    University essay from Linköpings universitet/Reglerteknik

    Author : Jacob Eek; [2021]
    Keywords : Coded aperture snapshot spectral imaging; CASSI; Raman; Raman spectroscopy; Explosive; Detection; Hyperspectral Image; HSI; Compressed sensing; Compressive Sensing; CS; Machine Learning; Reconstruction; Inverse problem; Generative Adversarial Network; GAN; CGAN; BEGAN; Latent variable optimization;

    Abstract : Fast detection and identification of unknown substances is an area of interest for many parties. Raman spectroscopy is a laser-based method allowing for long range no contact investigation of substances. READ MORE

  5. 14. Hyperspectral Image Registration and Construction From Irregularly Sampled Data

    University essay from Linköpings universitet/Datorseende

    Author : Hannes Freij; [2021]
    Keywords : ;

    Abstract : Hyperspectral imaging based on the use of an exponentially variable filter gives the possibility to construct a lightweight hyperspectral sensor. The exponentially variable filter captures the whole spectral range in each image where each column captures a different wavelength. READ MORE

  6. 15. Image simulations of the mission Martian Moons eXploration

    University essay from KTH/Rymdteknik

    Author : Romain Domagala; [2020]
    Keywords : ;

    Abstract : Martian Moons eXploration is a JAXA-lead mission aiming at exploring the moons of Mars, Phobos and Deimos. The hyperspectral infrared camera provided by France should perform global mapping of Phobos at high resolution in order to characterize surface composition and therefore help determine the origins of the moons.
