PostPic: A PostgreSQL extension for image-processing
PostPic is an extension for the open source PostgreSQL dbms that enables image processing inside the database, like PostGIS does for spatial data. It adds the new 'image' type to the SQL, and several functions to process images and to extract their attributes.
select * from images where date(the_img) > '2009-01-01'::date and size(the_img) > 1600;
Traditional relational clauses can be combined in queries with image-related ones, and basic image processing can be performed in SQL.
Contents of this package
This package contains the following:
- server: sources for the server extension
