General scope of activities


      Since the beginning of SAR imagery, the image processing and understanding team of Telecom Paris is working on the developpement of image processing tools dedicated to these particular data. The following research axes are developed :
      •  Speckle reduction and enhancement of SAR data (deep learning methods, non local approaches, dictionnary based approaches, TV regularization, markovian modeling and adapted optimization tools)
      •  Multi-temporal analysis (deep learning methods, non local approaches, statistical tests, local descriptors)
      • Understanding and information extraction (statistical modeling, phase vortex, graphs of primitives, stable points and corner reflectors, deep learning methods)
      • 3D reconstruction (interferometric and tomographic approaches with regularization priors)
      • Fusion of SAR and optical data (SVM, statistical methods)
      More recently the group is evolving towards multi-spectral and hyperspectral imaging.
