The uniformity measure shows slight variation in values
for evening, mid-day and sunny due to the obvious reason
that this parameter is selected to detect dynamic variation in
images, while these categories differ in only light
composition. Variation in this feature is very distinct for both
indoor classes as well. These two features have proven to be
valuable for classification purposes as they show variations
which are independent of each other. If a drastic change is
observed in these features with respect to previous values,
environment classification takes place which will redefine the
Canny parameter (Senv).
