Career and research
In 1984, he started to work in the field of computer vision at the University of Edinburgh. Together with Andrew Blake they wrote the book Visual reconstruction published in 1987, which is considered one of the seminal works in the field of computer vision. According to Fitzgibbon (2008) this publication was "one of the first treatments of the energy minimisation approach to include an algorithm (called "graduated non-convexity") designed to directly address the problem of local minima, and furthermore to include a theoretical analysis of its convergence."
In 1987, he moved back to England to the University of Oxford, where he joined Mike Brady's newly founded robotics research group as a University Research Lecturer, and started to work on multiple-view geometry. According to Fitzgibbon (2008) his "geometry was successful in showing that computer vision could solve problems which humans could not: recovering 3D structure from multiple images required highly trained photogrammetrists and took a considerable amount of time. However, Andrew's interests turned to a problem where a six-year-old child could easily beat the algorithms of the day: object recognition."
