Maxwellian Eye Fixation during Natural Scene Perception

Figure 3

Probability density function (PDF) of eye-movement amplitudes for each participant (P1 to P8). For each graph, we show the frequency (in percentage points) as a function of amplitudes (in arcmin). The experimental PDF is shown in the full line, and Maxwell’s theoretical PDF in the dotted line. For each participant, data of the 16 scenes were pooled together. Bin width was optimized using Nash and Sutcliffe’s criterion and set to 𝑚/2 arcmin, where 𝑚 is the mean amplitude of eye movements. KS: Kolmogorov-Smirnov (KS) two-sample test between experimental and theoretical PDFs.
