dmimgdist

Synopsis

Computes the distance transform of image

dmimgdist  infile outfile [tolerance] [clobber] [verbose]

Description

`dmimgdist' finds how far away each pixel is away from the border; where 'the border' is determined from the actual image boundary, any NULL/NaN values , or values less-than or equalto the tolerance value.

Example

dmimgdist img.fits dist.fits tol=0

computes the distance from the edge of the image, any null/nan pixels, and pixels below or equal to 0.

Parameters

Detailed Parameter Descriptions

Parameter=infile (file required filetype=input)

Input image

Parameter=outfile (file required filetype=output)

Output image

The image represents the distance to the edge

Parameter=tolerance (real)

Value below which to consider background

the distance to pixels above this tolerance are computed

Parameter=clobber (boolean default=no)

Remove output if it exists?

Used to specify whether or not to clobber existing file that has the same name as the specified output file

Parameter=verbose (integer default=0 min=0 max=5)

The tool chatter level

Verbose can be from 0 to 5, generating different amounts of debugging output.
