ZHANG Bing. Advancement of hyperspectral image processing and information extraction[J]. Journal of Remote Sensing, 2016,20(5):1062-1090. DOI: 10.11834/jrs.20166179.
Hyperspectral remote sensing is an important technique in Earth observation. Hyperspectral image processing and information extraction is one of the key issues in hyperspectral remote sensing. This paper introduces the major characteristics of hyperspectral remote sensing. It also summarizes and reviews the development history and current advancements of hyperspectral image processing and information extraction
which mainly comprises four aspects: data dimensionality reduction
pixel unmixing
image classification
and target and anomaly detection. Moreover
the high-performance computing technique in hyperspectral image processing and information extraction is summarized and analyzed. In the future
the technical developments of intelligent information analysis and high-performance processing based on hardware indicate that the hyperspectral remote sensing satellite system will enter an intelligent era. Therefore
the present studyindicates three aspects that should be considered in hyperspectral image processing and information extraction. First
a multidisciplinary connection should be emphasized
and new achievements in the fields of machine learning and artificial intelligence should be fully adopted.Second
close attention should be given to the integration of software and hardware to develop a high-performance technique for processing hyperspectral images in real time. Finally
the advantages and characteristics of hyperspectral remote sensing should be extensively explored
and the development of new theories and new methods should integrate the requirements of various applications.
