1. 1. Oscillations in a complex sunspot: From theory to data

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Femke Kranenbarg; [2024]
   Keywords : ;

   Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

4. 3. 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
