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
