Fractal dimension and the navigational information provided by natural scenes - Fig 4

<p><b>The relationship between the Fractal dimension (FD) (top row) and the depth of the rotational image difference function (rotIDF) (bottom row)</b>. Shown are the rotIDFs for the same scene (location 1) when the Fractal Dimension (FD) is maximum (red) and minimum (blue) in the morning (<b>A</b>), the afternoon (<b>B</b>) and the evening (<b>C</b>). Note that there appears to be an inverse relationship between FD and the depth (d) of the rotIDF.
