    Seminar LIGM : Convergent geometric estimators with digital volume and surface integrals

    Logo LIGM

    The next seminar of the team A3SI FILM (joint research unit of the East Paris University) will be held Tuesday, June 7 from 11:00 to 12:00, room 260 (ESIEE Paris). Convergent geometric estimators with digital volume and surface integrals Jacques-Olivier Lachaud LAMA, Université de Savoie Résumé : This talk presents several methods to estimate geometric quantities on subsets of the digital space Z^d. We take an interest both on global geometric quantities like volume and area, and on local geometric qu ...

    Seminar LIGM : Multidisciplinary Computational Anatomy for Medical Image Analysis: From Shape to Function and Pathology

    Logo LIGM

    Date : Friday, March 18 from 11:00 to 12:00, room 160 Yoshinobu Sato, NAIST, Japan Abstract: Computational anatomy models statistically represent inter-subject variability of human anatomy including individual organ shapes and their interrelations. These models are regarded as prior probabilities of human anatomy and can be utilized for Bayesian estimation problems related to anatomical identification. This talk presents medical image analysis of the abdominal organs and musculoskeletal structures usin ...

    Seminar LIGM : on connectivity of discretized explicit 2D curve and 3D surface

    Logo LIGM

    Date : Thursday, February 18 from 13:00 to 14:00, room 260 Akihiro Sugimoto - NII, Japan Abstract: Preserving connectivity is an important property commonly required for object discretization. Connectivity of a discretized object differs depending on how to discretize its original object. The morphological discretization is known to be capable of controlling the connectivity of a discretized object, by selecting appropriate structuring elements. The analytical approximation, which approximates the morpho ...

    Thesis Laurent Noël

    Abstract : Nowadays, computer generated images can be found everywhere, through a wide range of applications such as video games, cinema, architecture, publicity, artistic design, virtual reality, scientific visualization, lighting engineering, etc. Consequently, the need for visual realism and fast rendering is increasingly growing. Realistic rendering involves the estimation of global illumination through light transport simulation, a time consuming process for which the convergence rate generally decr ...

    Software Defined Radio for Cognitive Wireless Sensor Networks: A reconfigurable IEEE 802.15.4 Standard Date: Wednesday 14th of October, 14:00 The Increasing number of Wireless Sensor Networks (WSNs) applications has led industries to design the physical layer (PHY) of these networks following the IEEE 802.15.4 standard. The traditional design of that layer is on hardware suffering from a lack of flexibility of radio parameters, such as changing both frequency bands and modulations. This problem is emph ...

    Séminaire LIGM - Stereo camera based drivable area detection for autonomous driving

    Logo LIGM

    Date: Monday 12th of October, 1:30 p.m. to 2:30 p.m., room 160 Stereo camera based drivable area detection for autonomous driving Takuya Nanri - Nissan Co., Japan Abstract: We propose a general-purpose road boundary detection method, which can detect low height curbs, curved curbs, vegetation and ditches. Many conventional methods based on Digital Elevation Map (DEM) can only deal with ordinary curbs because they focus on step-edge detection in DEM. The proposed method adopts a dedicated edge detectio ...

    THE USE OF GEOMETRIC STRUCTURES IN GRAPHICS AND OPTIMIZATION Date: Wednesday 7th of October 2015 - 10:00 - AMPHI 160, ESIEE Paris, Noisy-le-Grand Abstract: Real-world data has a large geometric component, exhibiting significant geometric patterns. Therefore exploiting the geometric nature of data to design efficient methods has become a very important topic in several scientific fields, e.g., computational geometry, discrete geometry, computer graphics. In this thesis we use geometric structures to desig ...

    Soutenance de thèse Hironobu Fujiyoshi

    Date : Friday 25th of September - 1:30 p.m. to 2:30 p.m., room 160 Fast object detection with binary feature representation Abstract: Object detection involves classification of a huge number of detection windows obtained by raster scanning of an input image. In this talk, we introduce an approximate computation of linear SVM with binary feature representation to object detection. We will show that the proposed method is about 16 times faster than the conventional HOG and linear SVM and improves the clas ...
