This plugin filters duplicate images using perceptual image hashing.


  1. Git clone to plugins.local/af_img_phash

If you can't use count bits on PostgreSQL, you can do the following:

  1. Install the SQL function in sql/bitcount_funcdef_pgsql.sql
  2. Add the following option to config.php:

    	define('IMG_HASH_SQL_FUNCTION', true);

Note that using native SQL hashing function would be several orders of magnitude slower than count bits which may affect overal tt-rss performance.
