  1. 1. Unsupervised Change Detection Using Multi-Temporal SAR Data : A Case Study of Arctic Sea Ice

    Master-uppsats, KTH/Geodesi och geoinformatik

    Författare :Linda Fröjse; [2014]
    Nyckelord :sea ice; the Arctic; Kittler-Illingworth; generalized Gaussian distribution; log-normal distribution; ERS; ENVISAT; SAR; ASAR; havsis; Arktis; Kittler-Illingworth; generaliserad normaldistribution; lognormal distribtion; ERS; ENVISAT; SAR; ASAR;

    Sammanfattning : The extent of Arctic sea ice has decreased over the years and the importance of sea ice monitoring is expected to increase. Remote sensing change detection compares images acquired over the same geographic area at different times in order to identify changes that might have occurred in the area of interest. LÄS MER
