Package: proto
Usage
imscale input output mean
Parameters
- input
- Input image to be scaled.
- output
- Output scaled image.
- mean
- Scale the output image to this mean value.
- lower = INDEF
- Lower limit of window for calculating the input image mean. INDEF corresponds to the minimum possible pixel value.
- upper = INDEF
- Upper limit of window for calculating the input image mean. INDEF corresponds to the maximum possible pixel value.
- verbose = no
- Print the calculated input and output image means.
Description
The mean of the input image between the limits lower and upper is computed. The image is then scaled to the specified output mean.
Examples
To scale an image to a unit mean excluding deviant points below 1000 and above 5000.
