Multiresolution co-clustering for uncalibrated multiview segmentation
(2019-05-04)
Article
Restricted access - publisher's policyWe propose a technique for coherently co-clustering uncalibrated views of a scene with a contour-based representation. Our work extends the previous framework, an iterative algorithm for segmenting sequences with small ... -
Scientific, artistic and documentary investigation of a Picassian anonymous oil painting
(2017)
Article
Restricted access - publisher's policyAn anonymousoilpainting(The Comedians)with several and relevant Picassian features has been investigated in a global manner includingIRreflectometric analysis, non destructive pigment analysis with Raman ... -
Benchmark on automatic 6-month-old infant brain segmentation algorithms: the iSeg-2017 challenge
(2019-02-27)
Article
Restricted access - publisher's policyAccurate segmentation of infant brain magnetic resonance (MR) images into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF) is an indispensable foundation for early studying of brain growth patterns and ... -
Measuring traffic lane-changing by converting video into space–time still images
(2019-06)
Article
Open AccessEmpirical data is needed in order to extend our knowledge of traffic behavior. Video recordings are used to enrich typical data from loop detectors. In this context, data extraction from videos becomes a challenging task. ... -
The global navigation satellite systems reflectometry (GNSS-R) microwave interferometric reflectometer: hardware, calibration, and validation experiments
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-27)
Article
Open AccessThis manuscript describes the Microwave Interferometric Reflectometer (MIR) instrument, a multi-beam dual-band GNSS-Reflectometer with beam-steering capabilities built to assess the performance of a PAssive Reflectrometry ... -
Correspondence matching in unorganized 3D point clouds using Convolutional Neural Networks
(2019-03-08)
Article
Restricted access - publisher's policyThis document presents a novel method based in Convolutional Neural Networks (CNN) to obtain correspondence matchings between sets of keypoints of several unorganized 3D point cloud captures, independently of the sensor ... -
Depth estimation and semantic segmentation from a single RGB image using a hybrid convolutional neural network
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-04-15)
Article
Open AccessSemantic segmentation and depth estimation are two important tasks in computer vision, and many methods have been developed to tackle them. Commonly these two tasks are addressed independently, but recently the idea of ... -
Architectural optimization framework for earth-observing heterogeneous constellations : marine weather forecast case
(2019-01-25)
Article
Open AccessEarth observation satellite programs are currently facing, for some applications, the need to deliver hourly revisit times, subkilometric spatial resolutions, and near-real-time data access times. These stringent requirements, ... -
L-band vegetation optical depth seasonal metrics for crop yield assessment
(2018-06-01)
Article
Restricted access - publisher's policyAttenuation of surface microwave emission due to the overlying vegetation is proportional to the density of the canopy and to its water content. The vegetation optical depth (VOD) parameter measures this attenuation. VOD ... -
Incorporation of acoustic sensors in the regulation of a mobile robot
(2019-01-17)
Article
Restricted access - publisher's policyThis article introduces the incorporation of acoustic sensors for the localization of a mobile robot. The robot is considered as a sound source and its position is located applying a Time Delay of Arrival (TDOA) method. ... -
Spatial mode detection by frequency upconversion
(2019-02-01)
Article
Open AccessThe efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon bit-rates in classical and quantum communications. Such mode creation/detection is traditionally ... -
Tutorial on remote sensing using GNSS bistatic radar of opportunity
(Institute of Electrical and Electronics Engineers, 2014-12)
Article
Restricted access - publisher's policyIn traditional GNSS applications, signals arriving at a receiver's antenna from nearby reflecting surfaces (multipath) interfere with the signals received directly from the satellites which can often result in a reduction ...
