Weighted Version of a Measure
Description
Given a measure m
(object of class "msr"
)
and a spatially-varying weight function, construct the
weighted version of m
.
Usage
measureWeighted(m, w)
Arguments
m |
A measure (object of class |
w |
A pixel image (object of class |
Details
For any region of space B
,
the weighted measure wm
has the value
wm(B) = \int_B w(x) dm(x)
In any small region of space, the increment of the
weighted measure wm
is equal to the increment of the
original measure m
multiplied by the weight w
at that
location.
Value
Another measure (object of class "msr"
)
on the same spatial domain.
