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 inten‐
     sity of the whole blocks:

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