  • Date: January, 23 (usual seminar, 11:30)
  • Room : D106
  • Speaker: François Merciol (IRISA-OBELIX)
  • Title: Korrigan project
  • Abstract: This is the name of a R&T project with CNES, build upon our library for hierarchical trees called Triskele. The main goal is to provide a tool for data mining in a database of very larges images (several giga-pixels). The user makes a request by selecting a “patch” in one of the image in the database. Then the software looks in all the images using a sliding windows of the same size than the patch. The comparison is made using a method called Pattern Spectra. No learning phase is needed here. Also the object searched can be of any size and of any nature. The process uses 2 main stages: 1) an indexing stage that produces a set of reduced information for each image of the database. 2) a stage for finding the matching patches and creating a list of results.
    Keywords: remote sensing image, big image, tree representation, pattern spectra, linear algorithme
