報告題目:Automated Terrain Feature Identification from Remote Sensing Imagery: A Deep Learning Approach
主 講 人:李文雯 副教授(美國亞利桑那州立大學地理科學與城市規(guī)劃學院)
報告摘要:This talk introduces a novel deep learning framework to support terrain feature identification for automated landscape scene recognition and interpretation. Developing landscape scene recognition techniques are of critical importance for geospatial researchers to differentiate terrains, support autonomous driving and navigation, detect interesting targets, identify anomalies, aid search and rescue operations, inspect living conditions of refugee camps, among others. This work takes advantage of the rapid advancement in deep learning (DL) and convolutional neural networks (CNN), the maturation of high-performance computing hardware chips, and cloud platform as well as the proliferation of geospatial big data. It achieves automatic and high-performance terrain feature detection in the following ways: (1) it extends a popular object detection network by integrating deep and deeper CNNs, boosting up its capability in feature extraction; (2) it provides a comprehensive evaluation to identify the best combination of hyper-parameters that optimize the model performance; (3) it introduces ensemble techniques to further enhance the model’s predictive accuracy by the collective intelligence of multiple classifiers. We expect this work to contribute significantly to the advancement of terrain analysis and deep learning.
