Name: WlzSampleObj - efficient sub-sampling of domain objects.

Synopsis

WlzSampleObj [-o<output object file>]
           [-x<column sampling factor>]
           [-y<line sampling factor>]
           [-z<plane sampling factor>]
           [-a] [-e] [-i] [-g] [-m] [-p] [-h] [<input object file>]

Options

-x	column sub-sampling factor.
-y	line sub-sampling factor.
-z	plane sub-sampling factor.
-a	maximum value convolution kernel.
-e	median value convolution kernel.
-i	minimum value convolution kernel.
-g	gaussian convolution kernel.
-m	mean convolution kernel.
-p	point sampling.
-o	Output object file name.
-h	Help - print help message
-v	Verbose operation

By default the input object is read from the standard input and the output object is written to the standard output.

Description: Sub-samples a woolz interval domain object with grey values.

Examples

# An example of using WlzSampleObj to apply a scale transform
# (scale = 0.5) using point sampling:

WlzSampleObj -x 2 -y 2 -p <infile.wlz > outfile.wlz

# Sub-sampling an object using a gaussian convolution kernel
# with scale along rows = 0.3333 and the scale down columns
# 0.5.

WlzSobel -x 3 -y 2 -g -o outfile.wlz infile.wlz
