In this paper, we propose a new technique for the estimation of contrast enhancement curves of Dynamic Contrast Enhanced sequences, which takes the most from the interdependence between this...

We address the problem of computing a local orientation map in a digital image. We show that standard image grey level quantization causes a strong bias in the repartition of orientations, hindering...
Significant edges in the case of a non-stationary Gaussian noise (2007)
Abraham, Isabelle, Abraham, Romain, Desolneux, Agnes
In this paper, we propose an edge detection technique based on some local smoothing of the image followed by a statistical hypothesis testing on the gradient. An edge point being defined as a...

Classically, percolation critical exponents are linked to the power laws that characterize percolation cluster fractal properties. It is found here that the gradient percolation power laws are...
Variational Snake Theory (2002)
Agnes Desolneux, Variational Snake Theory, Lionel Moisan, Jean-michel Morel
In this chapter, we review briey the theory of edge detection and its non local version, the \snake", or \active contour" theory. The snakes are curves minimizing locally a contrast and...
