Image-based similarity search
This service provides an image-based similarity search. The only criterion is the similarity of motifs based on characteristics such as colors, textures, shapes and contrasts. The image-based similarity search currently offers access to a growing portfolio of more than 200,000 digitized objects (manuscripts, rare books, maps). Some of them belong to the absolute core and peak inventory of the cultural heritage of Bavaria and also to the national patrimony.
Instructions for useInstructions for use
You can use a picture from this thematic selection page to access the initial screen. However, you can also use any other image from bavarikon's extensive collection as a search template. To do this, activate the option "Zeige Bildähnlichkeitssegmente" (Show image recognition segments, eye icon), when viewing a certain image or an illustrated page of a book. Existing image segments are marked with a blue frame and can be used as a search template; one click triggers the recognition search. The search results can be opened and inspected in the viewer; they can also be used as a template for further recognition searches. Please note that the image segments are selected automatically. Incorrect or incomplete sections may occasionally occur, or segments with irrelevant content may be detected. Take your time: you will probably need several successive search attempts until you start getting useful results.
Search with upload
Upload your own image as a template for an image search
Please note:
- Format JPG/JPEG or PNG only! The recommended resolution is 150 to 300 ppi. Limit is 1500 KB per file.
- Images can be colored or grayscale (black & white), but should not be too pale. To avoid negative effects on the search result, use motifs without borders, without text and without much white space.
- Please note that a search with uploaded files takes longer than usual (about 15 to 20 seconds). The uploaded file will be deleted after the search.
