mean method for class "im".## S3 method for class 'im':
mean(x, \dots)"im").mean.default.x. An object of class "im"
describes a pixel image. See im.object)
for details of this class.
The function mean.im is a method for the generic
function mean for the class "im".
If the image x is logical-valued, the mean value of x is
the fraction of pixels that have the value TRUE.
If the image x is factor-valued, then the mean of x
is the mean of the integer codes of the pixel values.
Any arguments in ... are passed to mean.default.
In particular, using the argument trim will compute the
trimmed mean, as explained in the help for mean.default.
Other information about an image can be obtained using
summary.im.
