optimize2bw - optimzed color/gray image to bw conversation

SYNOPSIS

optimize2bw [-n|--denoise] [-d|--dpi DPI] [-h|--high VALUE] [-l|--low VALUE] [-r|--radius RADIUS] [-s|--scale SCALE] [-sd|--standard-deviation DEVIATION] [-t|--threshold VALUE] -i|--input FILE -o|--output FILE

optimize2bw --help

DESCRIPTION

ExactImage is a fast C++ image processing library. Unlike ImageMagick, it allows operation in several color spaces and bit depths natively, resulting in much lower memory and computational requirements. Some optimized algorithms operate in 1/20 of the time ImageMagick requires, and displaying large images can be as fast as 1/10 of the time the "display" program takes.

optmize2bw reads shaded, color or gray image files and does perform 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, --input FILE

Input file.

-o, --output FILE

Output file.

-n, --denoise

Remove ("denoise") single bit pixel noise.

-d, --dpi DPI

Scale to specified DPI.

-h value, --high value

High normalization value.

-l, --low VALUE

Low normalization value.

-r, --radius RADIUS

"unsharp mask" radius.

-s, --scale SCALE

Scale output by factor.

-sd, --standard-deviation DEVIATION

Standard deviation for Gaussian distribution.

-t, --threshold VALUE

Threshold value.
