Deep anomaly detection in hyperspectral images based on membership maps and object area filtering

作者:

Highlights:

• A framework is developed to detect anomalies in hyperspectral images accurately.

• First, principal component analysis (PCA) is applied to reduce dimensionality.

• A convolutional network is then proposed to learn the pixel pair similarities.

• A novel method entitled Object Area Filtering is used to remove undesired objects.

• The results are compared to other anomaly detection methods in time and accuracy.
