Hans Knutsson has more than 300 publications in image processing and machine learning. The 10 most cited have a total of more than 2300 citations, h-index = 32. He is one of the founding members of CMIV - the Center for Image Science and Visualization. He obtained his PhD in 1982. In 1984 - 1986 he held a Postdoctoral Fellowship position at the Rockefeller University Neurobiology Laboratory headed by Nobel Laureate Torsten Wiesel.
He suggested and developed a novel method of representation and estimation of local structure of multi-dimensional signals using tensors and tensor fields. He introduced Canonical Correlation based fMRI analysis.
In collaboration with LMI , the Laboratory for Mathematics in Imaging at Harvard Medical School and the Surgical Planning Laboratory in Boston he has also started a new line of research aiming at developing a common theoretical framework for sampling, representation and visualization of in vivo diffusion processes using MRI.
