DINOHash ONNX

Python implementation of DINOHash using ONNX Runtime, from https://www.arxiv.org/abs/2503.11195

This is a Python port of the Node.js implementation, providing perceptual image hashing using ONNX models.

Installation

uv add dinohash-onnx

Usage

from dinohash_onnx import DINOHash
import os

hash = DINOHash()
hash_hex = hash.hash(image_path)
print(f"Hex: {hash_hex}")

Example

See examples/example.py for a complete working example.
