motionEnergy

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 also these excellent tutorials on the 2D equivalent of these filters

INPUT

stimulus, a 3d matrix containing the x-y-t stimulus movie
display, structure containing the following fields:
- display.frameRate (in Hz)
- display.ppd (pixels/degree) OR all of the following:
- display.width (in cm of physical screen)
- display.res.width (in pixels)
- display.dist (between eyes and screen, in cm)
theta, the angles at which motion energy should be computed (rightwards = 0, counterclockwise).
plotme, generate graphical output (default = false);

OUTPUT

motionenergy, length(theta) x size(stimulus, 3) motionenergy filter output filters (optional)
