Fractional Charlier Moments for Image Reconstruction and Image Watermarking

FrCPs are derived algebraically using the spectral decomposition of Charlier polynomials (CPs), then the Lagrange interpolation formula is used to derive the spectral projectors. Then, each spectral projector matrix is dec...

Higher-order reconstruction: from finite volumes to discontinuous Galerkin

This work is concerned with the introduction of a new numerical scheme based on the discontinuous Galerkin (DG) method. We follow the methodology of higher order finite volume (FV) and spectral volume (SV) schemes and introduce a reconst...
