The field of computer vision has its roots in the modeling of the human
visual system (HVS); an extremely challenging task that generations of
researchers have attempted with limited success. Vision is a very
natural capability and it is commonly accepted that about 80% of what
we perceive is vision-based. The highly intuitive nature of the HVS
makes it difficult for us to understand the myriad of problems
associated with computer vision, in contrast to sophisticated analytic
tasks such as playing chess.

Thus computer vision became a widely underestimated scientific problem,
maybe one of the most underestimated problems of the past decades. Many
AI researchers believed that the real challenges were symbolic and
analytic problems and visual perception was just a simple sub-problem,
to be dealt with in a summer project, which obviously failed. The truth
is that computers are better than humans at playing chess since Deep
Blue, but first now computers are, thanks to modern machine learning,
superior to humans on generic vision tasks.

The research at the Computer Vision Laboratory (CVL) has a strong focus
on theory and methods, which are applied in application domains where
technical systems are supposed to coexist with – and therefore predict
actions of – humans, e.g. regarding self-driving cars sharing road
space and interacting with humans. Other addressed application domains
are monitoring of greenhouse gases, sustainable forestry, and
monitoring of animals on the individual level.

CVL's research topics cover a wide range of problems within machine
learning for computer vision and robot perception:

  • Continuous-time modeling of 3D motion
  • Estimation of pose and 3D structure
  • Few-shot and weakly supervised learning
  • Geometric deep learning
  • Human and animal motion analysis
  • Medical imaging
  • Quantum machine learning
  • Reinforcement learning
  • Remote sensing
  • Semi- supervised and incremental learning
  • Scene flow estimation
  • Uncertainty representation
  • Video and semantic segmentation
  • Vision for action

Swedish AI research gets more muscle

The supercomputer Berzelius was inaugurated in the spring of 2021, and was then Sweden's fastest supercomputer for AI. Yet, more power is needed to meet the needs of Swedish AI research.

Successful premiere for ISY's PhD Workshop

For the first time the Department of Electrical Engineering organized an all-day conference dedicated solely to the department's PhD-students. Afterwards the director of PhD studies, Mark Vesterbacka, was more than satisfied when he summed up the day

Human vision – a challenge for AI

Achieving diversity in human vision is one of the major challenges for AI research. In the vast majority of cases, we are better than machines at understanding the world around us. But machines are catching up – slowly but surely.

AI: Helping criminal investigators find digital evidence

Cyberattacks are an increasing threat to society. So, for crime investigators, digital evidence is becoming more important in the hunt for criminals. And the technology exists – not least at Linköping University, where AI is an area of excellence.

Facial recognition

Facial recognition used in more and more ways

Research into facial recognition has been under way for a long time, but has really taken off in recent years. “The technology is beginning to be used in more and more contexts”, says Jörgen Ahlberg, researcher in computer vision.
