  1. 16. Object Detection in Infrared Images using Deep Convolutional Neural Networks

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Markus Jangblad; [2018]
    Keywords : Object detection; Infrared images; Deep Convolutional Neural Network; Objektdetektering; Infraröda bilder; neurala nätverk;

    Abstract : In the master thesis about object detection(OD) using deep convolutional neural network(DCNN), the area of OD is being tested when being applied to infrared images(IR). In this thesis the, goal is to use both long wave infrared(LWIR) images and short wave infrared(SWIR) images taken from an airplane in order to train a DCNN to detect runways, Precision Approach Path Indicator(PAPI) lights, and approaching lights.

  3. 17. Tree species classification using multi-temporal Sentinel-2 data

    University essay from SLU/Dept. of Forest Resource Management

    Author : Magnus Persson; [2018]
    Keywords : sentinel-2; tree species; random forest; recursive feature elimination;

    Abstract : The Sentinel-2 program provides the opportunity to monitor terrestrial ecosystems with a high temporal- and spectral resolution. In this study, the utilization of multi-temporal Sentinel-2 imagery and it’s spectral variation due to phenology for classification of common tree species is evaluated at the forest estate Remningstorp in central Sweden.

  4. 18. Compressive Sensing: Single Pixel SWIR Imaging of Natural Scenes

    University essay from Linköpings universitet/Datorseende

    Author : Andreas Brorsson; [2018]
    Keywords : Compressed sensing; Compressive sensing; CS; Compressive imaging; compressed imaging; CI; SPC; Single pixel camera; single pixel imaging; SWIR; Short-wavelength infrared; IR; infrared; Natural Scenes; DMD; Digital micromirror device; FOI;

    Abstract : Photos captured in the shortwave infrared (SWIR) spectrum are interesting in military applications because they are independent of what time of day the pic- ture is captured because the sun, moon, stars and night glow illuminate the earth with short-wave infrared radiation constantly. A major problem with today’s SWIR cameras is that they are very expensive to produce and hence not broadly available either within the military or to civilians. READ MORE

  5. 19. Comparison of multi-temporal and multispectral Sentinel-2 and Unmanned Aerial Vehicle imagery for crop type mapping

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stephania Zabala Ramos; [2017]
    Keywords : classification; Random Forest; precision agriculture; UAV; remote sensing; Micasense; GEM; Earth and Environmental Sciences;

    Abstract : Precision Agriculture aims to maximize crop production and the efficiency of land use to meet the increased demand for food while minimizing environmental impact and economic cost of food production. Crop type maps are needed for Precision Agriculture applications and remote sensing techniques are an efficient way to produce this information. READ MORE

  6. 20. Landsat and MODIS Images for Burned Areas Mapping in Galicia, Spain

    University essay from KTH/Geodesi och geoinformatik

    Author : Pablo Mazuelas Benito; Ana Fernández Torralbo; [2012]
    Keywords : ;

    Abstract : The extent, frequency and intensity of forest fires in Mediterranean regions have become an important problem in recent decades. Nowadays, remote sensing is an essential tool for the planning and management of the land at different scales. READ MORE
