imgdiff
Faster than the fastest in the world pixel-by-pixel image difference tool.
imgdiff isn't as fast as a tool like this should be and I'm not proud of it, but it is 3X faster than the fastest in the world pixel-by-pixel image difference tool, so maybe you'll find it useful.
Features
It can do everything odiff can. Faster.
Benchmarks
I've tested it on Linux, Intel(R) Core(TM) i7-4700HQ CPU @ 2.40GHz, 8 cores.

Usage
Usage: imgdiff [--threshold THRESHOLD] [--diff-image] [--fail-on-layout] BASE COMPARE OUTPUT
Positional arguments:
BASE Base image.
COMPARE Image to compare with.
OUTPUT Output image path.
Options:
--threshold THRESHOLD, -t THRESHOLD
Color difference threshold (from 0 to 1). Less more precise. [default: 0.1]
--diff-image Render image to the diff output instead of transparent background. [default: false]
--fail-on-layout Do not compare images and produce output if images layout is different. [default: false]
--help, -h display this help and exit
Download
You can find pre-built binaries here. imgdiff is written in Go, so there shouldn't be any troubles to compile it for the most of popular platforms.
