phash2 - npm explorer

Node pHash Wrapper

A wrapper for pHash using N-API and Promises.

Supported:
* Images (DCT and MH hashses, and respective hamming distance calculators)
* Video (DCT hashing and distance calculator). Note that this segfaults in pHash. Possibly due to deprecated ffmpeg code.

Usage

For API documentation please see types/index.d.ts.

Also see test.js for an example usage.
