AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Digital holographic microscopy (DHM) is an interferometric technique, providing quantitative mapping of the phase shift induced by semi- transparent microscopic specimens, such as cells, with sub-wavelenght resolution along the optical axis. Thanks to actu ...
A Fourier-based approach is presented for the investigation of multilayer superpositions of periodic structures and their moire effects. This approach fully explains the properties of the superposition of periodic layers and of their moire effects, both in ...
Motivated by the fractal-like behavior of natural images, we propose a new smoothing technique that uses a regularization functional which is a fractional iterate of the Laplacian. This type of functional has previously been introduced by Duchon in the con ...
A new code, SEMAL, has been developed which solves the linearized Vlasov-Maxwell wave equations to all orders in Larmor radii. Arbitrary density and temperature profiles as well as non-uniform magnetic fields are considered in slab geometry. The vacuum reg ...
In this report we propose a new coding scheme based on the Matching Pursuit algorithm and exploiting some of the new features introduced by H.264 for motion estimation. Main points of this work are the design of a redundant dictionary suitable for coding d ...
A new approach is presented for investigating the superposition of any number of periodic structures, and the Moire effects which may result. This approach, which is based on an algebraic analysis of the Fourier-spectrum using concepts from the theory of g ...
In the present article we give a full quantitative analysis of the multichromatic moire effects in the superposition of coloured periodic layers, which is based both on the Fourier theory and on the theory of colorimetry and colour vision. This is done by ...
