Whitening (i.e., flattening of the power spectra of retinal stimulation) under fixational eye movements.

This repo contains analysis scripts, figures, and some intermediate data for the paper "Exploration of Functional Consequences of Fixational Eye Movements in the Absence of a Fovea".

ConvertPPM2JPGand16to8Bit.m : used once for format conversion
ProcessRawEyeMovements.m : used once to process raw eye movements.
WhiteningSpectralAnalysisGPU.m : The MAIN analysis function. Uses GPU.
ComputeAveragePSDs.m : as the name suggests, it was used to compute average PSD. It must be run again if WhiteningSpectralAnalysisGPU is run again.
FancyFinalPlots.m : The final plotting script for publication quality images.

There are also several short scripts under utils/ to generate some of the intermediate data or figures.

We used 100 natural images from http://natural-scenes.cps.utexas.edu/db.shtml (~40deg field of view horizontally).
