11th IAPR Workshop on Pattern Recognition in Remote Sensing

January 2021 - virtual event


This workshop has established itself as an important event for scientists involved in the combined fields of pattern recognition and remote sensing. These two research fields have always overlapped, but an ever-increasing amount of observations at varying scale, temporal, and spatial resolution provided by a multitude of different sensors require novel advanced algorithms and techniques for automated analysis.
