  1. 1. Computer Vision for Camera Trap Footage : Comparing classification with object detection

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Fredrik Örn; [2021]
    Nyckelord :computer vision; camera traps; classification; object detection; neural networks; artificial intelligence; machine learning; datorseende; kamerafällor; klassificering; detektering; neurala nätverk; artificiell intelligens; maskininlärning;

    Sammanfattning : Monitoring wildlife is of great interest to ecologists and is arguably even more important in the Arctic, the region in focus for the research network INTERACT, where the effects of climate change are greater than on the rest of the planet. This master thesis studies how artificial intelligence (AI) and computer vision can be used together with camera traps to achieve an effective way to monitor populations. LÄS MER

  2. 2. Detecting exoplanets with machine learning : A comparative study between convolutional neural networks and support vector machines

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Jacob Tiensuu; Maja Linderholm; Sofia Dreborg; Fredrik Örn; [2019]
    Nyckelord :Machine learning; Exoplanet; Support vector machine; Convolution neuralnetwork;

    Sammanfattning : In this project two machine learning methods, Support Vector Machine, SVM, and Convolutional Neural Network, CNN, are studied to determine which method performs best on a labeled data set containing time series of light intensity from extrasolar stars. The main difficulty is that in the data set there are a lot more non exoplanet stars than there are stars with orbiting exoplanets. LÄS MER
