Synopsis
Computes the distance transform of image
Syntax
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
name | type | ftype | def | min | max | reqd |
---|---|---|---|---|---|---|
infile | file | input | yes | |||
outfile | file | output | yes | |||
tolerance | real | |||||
clobber | boolean | no | ||||
verbose | integer | 0 | 0 | 5 |
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.
