    Soutenance de thèse de Imen MELKI

    Le 22 Juin 2015 à 10h 00, Amphi 110, ESIEE Paris VERS UN SYSTEME AUTOMATISE POUR LA DETECTION ET LA QUANTIFICATION DES LESIONS CORONAIRES DANS DES ANGIOGRAPHIES CT CARDIAQUES Résumé : Les maladies coronariennes constituent l'ensemble des troubles affectant les artères coronaires. Elles sont la première cause mondiale de mortalité. La détection précoce de ces maladies en utilisant des techniques peu invasives permet de réduire les coûts et les risques liés à une approche interventionnis ...

    Séminaire LIGM - Understanding deep features with computer-generated imagery

    Logo Laboratoire Gaspard Monge

    Date : Wednesday, May 13 at 15:00 Understanding deep features with computer-generated imagery Mathieu AUBRY LIGM/ENPC and UC Berkeley Abstract: We introduce an approach for analyzing the variation of features generated by convolutional neural networks (CNNs) trained on large image datasets with respect to scene factors that occur in natural images. Such factors may include object style, 3D viewpoint, color, and scene lighting configuration. Our approach analyzes CNN feature responses with r ...

    Séminaire LIGM - Efficient Incremental Computation of Families of Component Trees

    Logo Laboratoire Gaspard Monge

    Date : Tuesday, May 12th from 1:30 p.m. to 2:30 p.m. "Efficient Incremental Computation of Families of Component Trees" Ronaldo Fumio Hashimoto University of São Paulo, Brazil Abstract: Component tree allows an image to be represented as a hierarchy of connected components. These components are directly related to the neighborhood chosen to obtain them and, in particular, a family of component trees built with increasing neighborhoods allows the linking of nodes of different trees acco ...

    Séminaire LIGM - Labeling the world

    Logo Laboratoire Gaspard Monge

    Date : Thursday, May 7 at 11:00 "Labeling the world" Bryan C. Russell Adobe Research Abstract: Much of our 3D visual world is described in auxiliary data, such as online text and maps. In this talk I will describe two works that reason about such auxiliary data, together with reconstructed 3D geometry. In the first part I'll describe an approach for analyzing Wikipedia and other text, together with online photos, to produce annotated 3D models of famous tourist sites. The approach is ...

    Séminaire LIGM - Stable radial distortion calibration by polynomial matrix inequalities programming

    Logo Laboratoire Gaspard Monge

    Date : Wednesday, 15 April - 11:00 "Stable radial distortion calibration by polynomial matrix inequalities programming" Tomas Pajdla Czech Technical University in Prague Abstract: Polynomial and rational functions are the number one choice when it comes to modeling of radial distortion of lenses. However, several extrapolation and numerical issues may arise while using these functions that have not been covered by the literature much so far. In this paper, we identify these problems and ...
