Improving the sharpness of an image

Centre National d'Etudes Spatiales CNES - 10/17/2016


Procedure for correcting a digital image containing artefacts due to aliasing. The spectral folding occurs when the sampling frequency of a continuous signal for the digitisation of said signal does not abide by Shannon's Theorem.


Universality - Processing of all types of digital image


Effective processing - Detection of aliasing of an edited digital image - Generation of an over-sampled output image from an input image containing aliasing Practical procedure - Applicable to all types of image acquisition
