    Covenantee:   Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de Barcelona
    Surface polaritons are key elements in multiple applications within the field of nanopho- tonics because of their ability to concentrate electromagnetic energy down to length scales comparable to the wavelength λ0 of ...
  • Automatic pattern detection on images for multiple-sensor calibration 

    Torras Estruch, Joan (Universitat Politècnica de Catalunya, 2021-09-10)
    Master thesis
    Restricted access - author's decision
    Covenantee:   Institut de Ciències Fotòniques (ICFO) / Universitat de Barcelona / Universitat Autònoma de Barcelona
    Sensor calibration can be done by identifying known points of interest of a calibration pattern into the intensity images captured with the sensor. If the same exact points are identified using multiple sensors, then ...
