Probabilistic Vision Group

The probabilistic vision group is part of the McGill Centre for Intelligent machines. The focus of our research is on developing probabilistic inference techniques for computer vision problems. Such problems often involve processing noisy data; probabilistic approaches are then appropriate as they allow for uncertainty to be modelled and propagated through the solution process. Choosing to represent the solution to a computer vision problem as a probability distribution over many possible solutions makes it possible to measure the ambiguity of the results and provide guidelines as to whether more data should be acquired, when possible. Applications include, but are not limited to

  • Object recognition
  • Active vision
  • Image segmentation
  • Image registration
  • Image-guided neurosurgery
