ttrss-perceptual-image-hash

This plugin filters duplicate images using perceptual image hashing

• Hashing library: https://github.com/jenssegers/imagehash
• Count bits extension for PostgreSQL: https://github.com/sldab/count-bits

Installation

• Git clone to plugins.local/af_img_phash
• Install plugin schema into tt-rss database (sql/phash_schema_pgsql.sql or sql/phash_schema_mysql.sql)
• Enable in feed editor for specific feeds (after enabling the plugin)

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

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

• Install SQL hashing function in sql/bitcount_funcdef_pgsql.sql

• Add the following option to config.php:

  	define('IMG_HASH_SQL_FUNCTION', true);
