1. 1. Land cover classification using machine-learning techniques applied to fused multi-modal satellite imagery and time series data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Anastasia Sarelli; [2024]
   Keywords : Geography; GIS; Land Cover Classification; Landsat; Machine Learning; Earth and Environmental Sciences;

   Abstract : Land cover classification is one of the most studied topics in the field of remote sensing, involving the use of data from satellite sensors to analyze and categorize different land surface types. There are numerous satellite products available, each offering different spatial, spectral, and temporal resolutions. READ MORE

3. 2. Development of a Level-0 Geoprocessing Platform for a Multispectral Remote Sensing Payload

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Sergio Santiago Bernabeu Peñalba; [2022]
   Keywords : Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

   Abstract : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

5. 4. Tracking Under Countermeasures Using Infrared Imagery

   University essay from Linköpings universitet/Datorseende

   Author : Sara Modorato; [2022]
   Keywords : computer vision; infrared imagery; tracking; countermeasures; discriminative correlation filters; Efficient Convolution Operator tracker; Spatial-Temporal Regularized Correlation Filter tracker; Visual Object Tracking; flare; DIRCM; multiple wavelength bands; features;

   Abstract : Object tracking can be done in numerous ways, where the goal is to track a target through all frames in a sequence. The ground truth bounding box is used to initialize the object tracking algorithm. Object tracking can be carried out on infrared imagery suitable for military applications to execute tracking even without illumination. READ MORE

6. 5. Predicting biodiverse semi-natural grasslands through satellite imagery and machine learning

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Adrian Baggström; [2021]
   Keywords : Machine learning; remote sensing; biodiversity; plant species richness; semi-natural grasslands; Sentinel-2;

   Abstract : Semi-natural grasslands are amongst the most biodiverse ecosystems in Europe, though their importance they are experiencing a declining trend. To monitor and assess the health of these ecosystems is generally costly, personnel demanding and time-consuming. READ MORE
