imgSeek is a collection of free open source visual similarity projects. The query (image you are looking for) can be expressed either as a rough sketch painted by the user or as another image you supply (or an image in your collection). The searching algorithm makes use of multi resolution wavelet decomposition of the query and database images. Screenshot for the desktop version: by drawing that lousy red rectangle with black windows, a pale blue sky and the gray asphalt (on the left drawing widget), you get these 10 best matches (along with their score) from your collection of thousands of images.
This is a tool to create, design and edit database files compatible with SQLite.
