Urai AE & Wimmer K (2016). Spatiotemporal motion energy filtering: a Matlab implementation. Zenodo, http://doi.org/10.5281/zenodo.594505. Implements motion energy filtering as described in Adelson & Bergen (1985), on 3D moving dot stimuli as done in Kiani et al. (2008) and others. See tutorial.m for explanation of how to use the code. See also these excellent tutorials on the 2D equivalent of these filters http://www.georgemather.com/Model.html (George Mather) http://mplab.ucsd.edu/~marni/CSHL_Tutorials/MotionEnergy.tar (Simoncelli, Glimcher, Chichilnisky) http://www.cns.nyu.edu/~david/courses/perceptionGrad/syllabus2015.html (David Heeger) And see this version from the Gallant lab, which includes filtering over a color dimension: https://github.com/gallantlab/motion_energy_matlab Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
