Jónatas Miguel de Almeida Valença

Researcher

My research interests lie in Smart Structural Health Monitoring and Characterization; and Conservation of Structures and Built Heritage. In this scope, I have been developed tools based on computer vision (also applying machine and deep learning), and including processing hyper and multispectral images.
 
Domain of activity: Structural Health Monitoring
 
Research topics:
  • Automatic Inspection of Structures
  • Smart Structural Monitoring
  • Conservation of Concrete Heritage
  • Computer Vision
  • Photogrammetry
  • Image Processing and Correlation
  • Multi and Hyper-spectral Image Analysis
