NAME
optimize2bw - automatic thresholder of the ExactImage toolkit
SYNOPSIS
optimize2bw [option...] {-i | --input} input-file
{-o | --output} output-file
optimize2bw --help
DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other
library frameworks it allows operation in several color spaces and bit
depths natively, resulting in low memory and computational
requirements.
optimize2bw reads image files and performs automatic thresholding and
optional scaling on the data. It is useful for long term archiving of
documents that have to be stored in sub-byte black and white data to
reduce storage requirements.
OPTIONS
-i file, --input file
Read image from the specified file.
-o file, --output file
Save output image to the specified file.
-n, --denoise
Remove (“denoise”) single bit pixel noise.
-d n, --dpi n
Scale the image to the specified resolution.
-h n, --high n
Set high normalization value.
-l n, --low n
Set low normalization value.
-r n, --radius n
Set “unsharp mask” radius. The default is 0.
-s n, --scale n
Set output scale factor. The default is 1.0.
-sd x, --standard-deviation x
Set standard deviation for Gaussian distribution. The default is
0.0.
-t n, --threshold n
Set threshold value. The default is 0.
--help
Display help text and exit.
EXAMPLES
$ optimize2bw -i logo.jpg -o logo.tif
Scale: 0
