NAME

puzzle-diff - Compare pictures with libpuzzle

SYNOPSIS

[ -b <contrast barrier for cropping >] [ -c ] [ -C <max cropping ratio >] [ -e ] [ -E <similarity threshold >] [ -h ] [ -H <max height >] [ -l <lambdas >] [ -n <noise cutoff >] [ -p <p ratio >] [ -t ] [ -W <max width >] <file 1> <file 2>

DESCRIPTION

puzzle-diff compares two pictures and outputs the normalized distance.

Try puzzle-diff -h for more info.

EXAMPLES

Output distance between two images:

$ puzzle-diff pic-a-0.jpg pics-a-1.jpg
0.102286

Compare two images, exit with 10 if they look the same, exit with 20 if they don’t (may be useful for scripts):

$ puzzle-diff -e pic-a-0.jpg pics-a-1.jpg
$ echo $?
10

Compute distance, without cropping and with computing the average intensity of the whole blocks:

$ puzzle-diff -p 1.0 -c pic-a-0.jpg pic-a-1.jpg
0.0523151
