Meyer wavelet

The Meyer wavelet is an orthogonal wavelet proposed by Yves Meyer.

Quadrature mirror filter

Orthogonal wavelets -- the Haar wavelets and related Daubechies wavelets, Coiflets, and some developed by Mallat, are generated by scaling functions which, with the wavelet, satisfy a quadrature mirror filter relationship.

Stéphane Mallat

Specifically, he collaborated with Yves Meyer to develop the Multiresolution Analysis (MRA) construction for compactly supported wavelets, which made the implementation of wavelets practical for engineering applications by demonstrating the equivalence of wavelet bases and conjugate mirror filters used in discrete, multirate filter banks in signal processing.

Texture gradient

In 2000, a paper about the texture gradient equation, wavelets, and shape from texture was released by Maureen Clerc and Stéphane Mallat.
