  • Image boundary analysis and applications

    Implementation of an Edge Detection Method with Sub-pixel Accuracy in a Graphic Environment and Comparative Study for Applications in 2D and 3D Images.

  • Medical image analysis

    We developed a suite of techniques and processes to create images of the human body or parts thereof, for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and function).

  • Optical flow

    The computation of the optical flow in a sequence of images is a basic topic in the field of computer vision. It is the basis for a wide range of applications, such as: stereoscopic vision and three-dimensional scene reconstruction, motion analysis of objects in image sequences, medical image analysis, robot guidance and collision detection, among others. It consists in the estimation of the displacement experienced by objects in a scene from an image sequence. Our research center has spent many years working on this subject and has specialized in variational techniques. Such techniques are especially useful for optical flow estimation. These are currently among the most precise techniques that are known.

  • Stereoscopic and three-dimensional reconstruction of scenes

    Stereoscopic vision is the system that can capture the depth of a scene through a pair of related cameras. It has received much attention from the scientific community and has a special relevance, since it is equivalent to the human visual system. When we have two calibrated cameras that obtain images of a scene, then it is possible to know the 3D position of objects in space. It covers different topics such as: camera calibration, finding correspondences between images (similar to the problem of optical flow estimation) and three-dimensional reconstruction.

  • Land visualization

    The field of geographical information systems has suffered an important advance during the last years. This is due largely to the emergence of land visualization tools that are available through the Internet, and are able to handle large amounts of information. Moreover, government agencies have promoted greater transparency in access and transmission of such information. The emergence of new standards for managing geographic information has reinforced the fact that many organizations are providing free-form data.

    Our research center has participated in the development of technologies for the management of geographic information. We have created several graphics tools for terrain visualization, using these standard protocols.We have participated in several projects addressing the deployment of geo-referenced information to solve complex planning and management tasks. On the other hand, we have developed basic tools for displaying virtual globes on new mobile devices.
