pHashPy 0.1.2

Python bindings for the pHash (perceptual hashing) library.

pHashPy

Python bindings for the pHash (perceptual hashing) library.

Copyright (c) Dries007 2020.
Licensed under GPLv3 (or later), as is pHash itself.

The project uses cppyy to create a small wrapper around pHash functions.

Features

Working:

• Video hashing
• Image hashing (dct & mh)

Missing:

• Audio
• Text

Usage

As a Command Line Tool

You can use the tool as a command line utility to generate a list of hashes from a list of files.

Run python -m pHashPy --help for more info.

As a Library

Import functions from the package's __init__, this will automatically load the required library files. If you import the functions from the individual py files, you must call helper.init yourself.
