Where is the reflectance of pure vegetation while is
the reflectance ofnon-vegetation.
v R s R
We assume that the vegetation coverage proportion of a pixel is
, that is the vegetation fraction, then the non-vegetation
coverage proportion of the pixel is . If the whole pixel
is covered by vegetation, the reflectance we gain is ; if it
has no vegetation coverage, the reflectance is , so
and of a mixed pixel can be presented as a product of
and (Eq(5)), and (Eq(6)),
respectively:
