Description
Examples
Intensity( img, meas )
img
-
Image; input image
meas
(optional) name; intensity measure
The Intensity command computes an intensity measure of the layers of an image.
The img parameter specifies the input image. It may be a GrayImage, a ColorImage, or a ColorAImage. If a GrayImage, then a numeric value is returned. If a ColorImage or a ColorAImage, then a list of numeric values is returned, with each element corresponding to the value of the computation for the corresponding layer.
Intensity Measures
The optional meas parameter is a name that selects the computed measure of the intensity. Following are the allowable names and the meaning of each:
energy : energy of the pixel values (rms2)
maximum : maximum pixel value
mean : mean pixel value
minimum : minimum pixel value
range : range of the pixel values (minimum..maximum)
rms : rms of the pixel values
variance : variance of the pixel values
The default is range.
