Library for image hashing and deduplication.

Project description

# SDHash [![Build Status](](

A Python library for computing hashes of images which ignore perceptual differences.

## Usage

import sdhash
from PIL import Image

i1 ='test1.png')
i2 ='test1_noise.png')
i3 ='test2.png')

sdhash.test_duplicate(i1, i2) # True
sdhash.test_duplicate(i1, i3) # False
sdhash.hash_image(i1) # [ an md5 output ]

## Background

Suppose you want to test that two images are identical. The naive approach of simply comparing the byte-array representation of the two is not good.

## Algorithm

## Installation ##

The Python image library and NumPy/SciPy etc.

Installation is simple, via `pip`:

pip install sdhash


Resistance to rotation, mirroring etc.
Tunable knobs (for similarity detection etc.)
