Abstract

We observe a non-Gaussian heavy tailed distribution for the non-linear filter applied to the chromacity channel ’U’ (and equivalently to ’V’) on individual natural colour images in the colour space YUV. We fit a Generalised Gaussian Distribution (GGD) to the histogram of the filter response, and observe the shape parameter (α) to lie within the range 0 < α< 2, but rarely α> 1.
