Abstract: Disclosed is a method for diagnosis by reflectometry of a bundle of power lines including an input point and a plurality of branches, including the following steps: inserting (S50) electric markers having different frequency characteristics onto the branches of the bundle; injecting (S52) a test signal into the bundle from the input point; receiving (S54) a set of reflected signals produced by reflections of the test signal in the branches; analyzing all the reflected signals by identifying the markers and by assigning (S56) each reflected signal to one of the branches according to the frequency characteristic of the marker inserted onto the branch; and identifying the presence/absence of a defect in the branch by comparing (S58) the reflected signal assigned to the branch with a reflected signal model obtained by modelling the reflection of the test signal in the branch in the absence of any defect in the branch.

Abstract: The invention concerns a method for deformable fusion of a source multi-dimensional image (s(x)) and a target multi-dimensional image (t(x)) of an object, each image being defined on a multi-dimensional domain by a plurality of image signal samples, each sample having an associate position in the multi-dimensional domain and an intensity value, the method comprising estimating a smooth deformation field (d(x)) that optimizes a similarity criterion between the source image and the target image using a Markov Random Field framework, in near real-time performance. The similarity criterion is computed on transform coefficients obtained by applying a sub-space hierarchical transform to the image samples of the target image and to image samples obtained from the source image, an optimal tradeoff between a smoothness condition and the similarity criterion being automatically determined.

Abstract: A method and device for elastic registration of a two-dimensional source digital image of an object of interest with a slice of a three dimensional target volume of the object of interest is provided which defines a Markov Random Field framework having at least one undirected pairwise graph superimposed a two-dimensional image domain having at least a set of regular vertices and at least a set of edges, and defines a grid of control points, each control point corresponding to a vertex of the set of regular vertices, and a neighborhood system of edges associated with vertices. The method also defines a set of multi-dimensional labels of a discrete space to apply a displacement to each control point, the control point displacement defining a transformation adapted to obtain a plane slice of the target volume and an in-plane deformation transformation of the source digital image.
