PRRS 2020/2021

The International Association for Pattern Recognition (IAPR) Technical Committee 7 (TC-7 Remote Sensing and Mapping) organizes the 11th IAPR International Workshop on Pattern Recognition in Remote Sensing (PRRS 2020/2021). This workshop is held in conjunction with the International Conference on Pattern Recognition (ICPR 2020) ( The workshop is sponsored by IAPR and International Society for Photogrammetry and Remote Sensing (ISPRS).

Aims and Scope

As one of the flagship events of the International Association for Pattern Recognition, Pattern Recognition in Remote Sensing Workshop serves as an event bringing together researchers from both pattern recognition and remote sensing, with emphasis on the application of pattern recognition methods to remotely sensed data. The steady progress in the development of new remote sensing devices and remote sensing technology has led to ever increasing data and new challenges. Thus, need arises to apply the latest methods of machine learning and pattern recognition for automated analysis of this kind of data. This workshop will provide an ideal forum for spreading and exchanging the latest experiences of international researchers. Topics might be related to a large range of topics, including, but not limited to:
– Hyperspectral and multispectral image analysis
– Extraction, selection, learning, and reduction of features
– Deep learning for Earth observation data
– Clustering
– Active and transfer learning
– Multi-modal and multi-temporal analysis
– Image analysis of SAR and airborne thermal data
– Recognition of man-made objects from aerial and space platforms
– Novel pattern recognition tasks in remote sensing applications
– Technical reviews on related topics
