PDE-based denoising of complex scenes using a spatially-varying fidelity term
The widely used denoising algorithms based on nonlinear diffusion, such as Perona-Malik and total variation denoising, modify images toward piecewise constant functions. Though ed...

Light Logics and Optimal Reduction: Completeness and Complexity
Typing of lambda-terms in Elementary and Light Affine Logic (EAL , LAL resp.) has been studied for two different reasons: on the one hand the evaluation of typed terms using LAL ...

Complex Objects Pose Estimation based on Image Moment Invariants
— Moments are generic (and usually intuitive) descriptors that can be computed from several kinds of objects defined either from closed contours or from a set of points. In this...

Complexity of Compact Proofreading for Self-assembled Patterns
Abstract. Fault-tolerance is a critical issue for biochemical computation. Recent theoretical work on algorithmic self-assembly has shown that error correcting tile sets are possib...
