ISSIA VISION LAB

 ISSIA Vision Laboratory

We acquire and process images and multidimensional data to improve our understanding of the world around us, through  dedicated algorithms, the development of new prototypes and the study of complete intelligence

Our current research topics include:

  • Development of image acquisition prototypes with strict specifications
  • High resolution 3D vision systems for reconstruction of dense point clouds
  • Complex image processing
  • Machine learning algorithms in computer vision
  • New models for data analysis
  • Integration with field robotics for modeling and automatic interpretation of data
