Description
|
|
|
•
|
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 ( )
|
|
|
maximum : maximum pixel value
|
|
|
minimum : minimum pixel value
|
|
|
range : range of the pixel values ( )
|
|
|
rms : rms of the pixel values
|
|
|
variance : variance of the pixel values
|
The default is range.
