Application of Deep Learning for Environmental Information Extraction from Remote Sensing Imagery
thesisposted on 2019-02-19, 12:48 authored by Guang Xu
Convolutional Neural Network (CNN) is most promising for remote sensing imagery classification. However, a CNN model usually contains multiple convolutional and pooling layers for image feature extraction, which consumes lots of computational resources and makes it difficult for environmental scientists to utilize it. This study proposed the innovative Hierarchical Active Learning framework to deal with the situation when working with large satellite imagery with no need for a large number of labelled samples and expensive computational resources. The results of the study have demonstrated the value of multi-sourced data, which has opened up a new area in citizen science.
