An Enduring Dialogue between Computational and Empirical Vision

Susana Martinez-Conde, Stephen L. Macknik, David J. Heeger

Research output: Contribution to journalShort surveypeer-review


In the late 1970s, key discoveries in neurophysiology, psychophysics, computer vision, and image processing had reached a tipping point that would shape visual science for decades to come. David Marr and Ellen Hildreth's ‘Theory of edge detection’, published in 1980, set out to integrate the newly available wealth of data from behavioral, physiological, and computational approaches in a unifying theory. Although their work had wide and enduring ramifications, their most important contribution may have been to consolidate the foundations of the ongoing dialogue between theoretical and empirical vision science.
