A segmentation-based coding system allowing manipulation of objects (sesame)
(IEEE, 1996)
Conference report
Open AccessWe present a coding scheme that achieves, for each image in the sequence, the best segmentation in terms of rate-distortion theory. It is obtained from a set of initial regions and a set of available coding techniques. The ... -
Active mesh coding and rate-distortion theory
(Institute of Electrical and Electronics Engineers (IEEE), 1996)
Conference lecture
Open AccessThis paper presents a video coding scheme for very low bit rate applications. The coding approach relies on active meshes and can be viewed as a particular case of region-based coding. The active mesh is used to efficiently ... -
Analysis of stereo images using connected operators
(IEEE COMPUTER SOCIETY, 1997)
Conference report
Open AccessConnected operators are increasingly used in image processing due to their properties of simplifying the image with various criteria, without loosing contour's information. These properties are related to the connected ... -
Analysis of video sequences: table of content and index creation
(., 1999)
Conference report
Open AccessThis paper deals with the representation of video sequences useful for tasks such as long-term analysis, indexing or browsing. A Table Of Content and index creation algorithm is presented, as well as additional tools ... -
Anti-extensive connected operators with application to image sequences
(1997)
Conference lecture
Open AccessConnected operators are increasingly used in image processing They are at tractive in applications where the signal has to be simplified without loosing information about the contours A large number of simplification ... -
Antiextensive connected operators for image and sequence processing
(1998-04)
Article
Open AccessThis paper deals with a class of morphological operators called connected operators. These operators filter the signal by merging its flat zones. As a result, they do not create any new contours and are very attractive for ... -
Application of error modeling at the output of maximum likelihood decoder to concatenated coded 16 PSK
(Institute of Electrical and Electronics Engineers (IEEE), 1989)
Conference report
Open AccessThe authors study the performance of coded 16 PSK (phase shift keying) (inner code) concatenated with a Reed-Solomon (RS) code (outer code). The overall redundancy introduced by the codes is 33% (spectral efficiency 2.7 ... -
Arbre de partition binaire: Un nouvel outil pour la représentation hiérarchique et l’analyse des images hyperspectrales
(2011)
Conference report
Restricted access - publisher's policyThis problem discusses here is the hierarchical representation and processing of the hyperspectral imaging. In this framework, Binary Partition Trees (BPTs) are proposed as new hierarchical region-based representation. ... -
Auto-dual connected operators based on iterative merging algorithms
(Kluwer Academic Publishers, 1998)
Conference report
Open AccessThis paper proposes a new set of connected operators that are autodual. Classical connected operators are analyzed within the framework of merging algorithms. The discussion highlights three basic notions: merging order ... -
Bilateral distance based filtering for polarimetric SAR data
(2013-10-30)
Article
Open AccessThis paper introduces a non-linear Polarimetric SAR data filtering approach able to preserve the edges and small details of the data. It is based on exploiting the data locality in both, the spatial and the polarimetric ... -
Binary partition tree as a polarimetric SAR data representation in the space-time domain
(IEEE, 2011)
Conference lecture
Restricted access - publisher's policyThe aim of this paper is to present a Polarimetric Synthetic Aperture Radar data processing technique on the space-time domain. This approach is based on a Binary Partition Tree (BPT), which is a region-based and multi-scale ... -
Binary partition tree as an efficient representation for filtering, segmentation and information retreival
(Institute of Electrical and Electronics Engineers (IEEE), 1998)
Conference report
Open AccessThis paper discusses the interest of binary partition trees as shape-oriented image representations. Binary partition trees concentrate in a compact and structured representation a set of meaningful regions that can be ... -

(2000-04)
Article
Restricted access - publisher's policyThis paper discusses the interest of binary partition trees as a region-oriented image representation. Binary partition trees concentrate in a compact and structured representation a set of meaningful regions that can ... -
Combining graph neural networks and computer vision methods for cell nuclei classification in lung tissue
(Elsevier Ltd, 2024-04-15)
Article
Open AccessThe detection of tumoural cells from whole slide images is an essential task in medical diagnosis and research. In this article, we propose and analyse a novel approach that combines computer vision-based models with graph ... -
Comparison of MPEG-7 descriptors for long term selection of reference frames
(2009)
Conference lecture
Open AccessDuring the last years, the amount of multimedia content has greatly increased. This has multiplied the need of efficient compression of the content but also the ability to search, retrieve, browse, or filter it. Generally, ... -
Connected operators based on region-tree pruning strategies
(Barcelona, 2000)
Conference lecture
Open AccessThis paper discusses region-based representations useful to create connected operators. The filtering approach involves three steps: 1) a region tree representation of the input image is constructed; 2) the simplification ... -
