Shadow detection and removal is an important task when dealing with colour outdoor images. Shadows are
generated by a local and relative absence of light. Shadows are, first of all, a local decrease in the amount of
light that reaches a surface.

In this paper, we analyze the performance of
spectrum sensing based on energy detection. We do not assume
the exact noise variance is known a priori. Instead, an estimated
noise variance is used to calculate the threshold used in the
spectrum
