puzzle-diff

PUZZLE-DIFF(1)															    PUZZLE-DIFF(1)

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
