On the correspondence between objects and events for the diagnosis of situations in visual surveillance tasks
TLDR
A key problem in visual surveillance systems (VSS) is to find an effective procedure for linking the geometric descriptions of a scene at the object level with the corresponding descriptions of the agents intervening in this scene, as they are labelled by the same expert from geometric descriptions.

A block-based model for monitoring of human activity
TLDR
We present BB6-HM, a block-based human model for real-time monitoring of a large number of visual events and states related to human activity analysis, which can be used as components of a library to describe more complex activities in such important areas as surveillance, biomechanics or sports applications. Expand
On the effect of feedback in multilevel representation spaces for visual surveillance tasks
TLDR
In this work we propose a general top-down feedback scheme between adjacent description levels to interpret video sequences. Expand
Knowledge modeling for the image understanding task as a design task
TLDR
We model the image understanding task as a design task and define a generic problem solving method (PSM) that allows us to tackle the task in a hierarchical and recursive way. Expand
Segmentation of Moving Objects with Information Feedback Between Description Levels
TLDR
We propose a generic knowledge-based model to improve the segmentation process for detecting humans in video sequences. Expand
Towards a Semi-automatic Situation Diagnosis System in Surveillance Tasks
TLDR
This paper describes an ongoing project that develops generic components to help humans (semi-automatic system) in surveillance and security tasks in several scenarios. Expand
Well structured robot positioning control strategy for position based visual servoing
TLDR
We study a 3D visual servoing system composed of a robot manipulator, a CCD camera mounted on the end effector of the robot and a specific hardware. Expand
An Automatic System for the Location of the Optic Nerve Head from 2D Images
TLDR
In this paper, we present a vision system in order to improve the diagnosis process of patients with glaucoma. Expand
A Modular Scheme for Controller Design and Performance Evaluation in 3D Visual Servoing
TLDR
In this paper we present a modular scheme for designing and evaluating different control systems for position based dynamic look and move visual servoing systems. Expand
Tridimensional part modelling based on shape global features. Applications to recognition of parts measure by range finder sensors
TLDR
A new tridimensional modelling using a set of shape global features and a method for solving the 3D part recognition problem is described in this paper. Expand
