Researcher

Bartomeu Coll

Bartomeu Coll is a mathematician and computer-vision researcher whose work includes non-local image denoising. He completed a UAB doctorate in 1987 and led research projects in mathematical image processing and differential equations. His 2005 paper with Antoni Buades and Jean-Michel Morel introduced non-local means and received CVPR's Longuet-Higgins Prize in 2015; he later co-authored a deep-learning model for hyperspectral and panchromatic image fusion. As of October 2026, he is a full professor of applied mathematics at the University of the Balearic Islands and directs IAC3.

Timeline

  1. 1987

    A doctorate at UAB

    He completes a doctorate at UAB in 1987, supervised by Jaume Llibre.

  2. 1992–2016

    Leading image research projects

    He leads national research projects from 1992 and French CNES projects from 2006 to 2016. His research spans mathematical image processing and qualitative differential equations.

  3. 2005–2015

    Non-local image denoising

    In 2005, he, Antoni Buades and Jean-Michel Morel publish “A non-local algorithm for image denoising,” which proposes non-local means to average the colors of similar pixels. The paper receives the CVPR Longuet-Higgins Prize in 2015.

    Editing an imaging journal

    He edits SIIMS, the SIAM Journal of Imaging Sciences, from 2014 to 2018.

  6. 2023

    A deep unfolding network

    With Jamila Mifdal, Marc Tomás-Cruz, Alessandro Sebastianelli and Joan Duran, he publishes a deep-learning model for fusing hyperspectral and panchromatic images at CVPR Workshops in 2023.

  7. 2025

    Limit cycles in equations

    In 2025, he coauthors “More limit cycles for complex differential equations with three monomials.”

  8. As of October 2026
