LaViRIA

Research

Computer Vision

The main developments in computer vision at LaViRIA are:

  • Analysis of visual characteristics such as color and texture in order to automate tasks that use images as the key information.
  • Image classification and segmentation, in which the computer automatically determines the component elements of a scene.
  • Pattern and shape recognition, where visual models are independently searched for in an image.
  • Object tracking and visual servo-control that allow computers to perform dynamic vision tasks based on mathematical and computational models.

Mobile Robots

Our work in mobile robotics uses the XidooBot robot as the main experimental platform. Our goal is to equip this robot with artificial intelligence so that it can perform high-level robotic tasks.The developments we have made to date include:

  • Robotic navigation systems, which consist of getting the robot to carry out movement tasks between two points that can be specified both geometrically, as from sensory references or even using topological references.
  • Scenario modeling tasks, in order for the robot to generate useful representations to be able to complete the tasks entrusted to it.
  • Reactive navigation methods, which allow the robot to avoid obstacles present in its operating environment and which impede the efficient execution of the task in progress.

Computational Intelligence

At LaViRIA, the primary approach used to develop intelligent systems is based on flexible computing. Flexible computing is understood as a set of techniques and methods (among which are fuzzy systems, genetic algorithms and neural networks) that aims to solve engineering problems, synergistically integrating the benefits of the methods in a collaborative way more than competitive.

Over time, we have applied this expertise to real-time systems for image processing, computer vision, and mobile robotics applications.
