vnormal(1)

PROGRAM
vnormal - Normalize an image, forcing the pixel values to lie within a specified range.

SYNTAX

vnormal

-i  input image filename

-o  output image filename

-n  specifies normalization factor

[-V]
    Gives the version for vnormal

[-U]
    Gives the usage for vnormal

[-P]
    Prompts for command line options

[-A [file1]]
    Creates the answer file called vnormal.ans or file1

[-a [file1]]
    Uses vnormal.ans or file1 as the answer file

DESCRIPTION
vnormal computes that scale factor required to force the most positive pixel value in an image to be equal to the specified normalization target value, and then performs the required scaling.

This routine is really just a front-end for lvconvert(3).

REQUIRED ARGUMENTS

-i  type: infile
    desc: input image filename

-o  type: outfile
    desc: output image filename

-n  type: float
    desc: specifies normalization factor

OPTIONAL ARGUMENTS
none

EXAMPLES
vnormal -i input.image -o output.image -n 10

This scales all of the pixels in input.image so that the most positive pixel is equal to 10. All pixels are multiplied by the same factor to accomplish this. The result in stored in output.image.

RESTRICTIONS
vnormal will not operate on transform input files.
