A-contrario ringing detection and Shannon-compliant images (2009)
Blanchet, Gwendoline, Moisan, Lionel, Rougé, Bernard
According to Shannon Sampling Theory, cardinal sine (sinc) interpolation is the optimal way to reach subpixel accuracy from a properly sampled digital image. However, for most images sinc...

Measuring the global phase coherence of an image (2008)
Blanchet, Gwendoline, Moisan, Lionel, Rougé, Bernard
The Fourier phase spectrum of an image is well known to contain crucial information about the image geometry, in particular its contours. In this paper, we show that it is also strongly related to...

Deconvolution by thresholding in mirror wavelet bases (2003)
Jérôme Kalifa, Stéphane Mallat, Bernard Rougé
The deconvolution of signals is studied with thresholding estimators that decompose signals in an orthonormal basis and threshold the resulting coefficients. A general criterion is established to...
