argentum1 Posts: 602 Registered: Apr 2004	posted 05-28-2006 01:40 PM There are many request for identification of marks. So, I am wondering if anyone has attempted to put togeather a recognition program. If there are facial recognition programs why not one for marks. This would be a massive project. Maybe a dissertation project? Anyone have 20 years to spare? IP: Logged

Abstract Establishing the identity of the craftsmen of old Norwegian silver objects can be accomplished through the recognition of master-marks. Manually searching through the 6000 master-marks and 250 city-marks is tedious and unreliable. Our-goal is to develop an efficient retrieval of images of master- and city-marks from large databases based on the shape content of the image. We are building an automatic retrieval system to browse through the entire database. The first step is to extract primitive visual features from the images and to retrieve images on the basis of these features. We have developed a prototype image database of master-marks from a catalog by scanning 171 of these marks which appear on silver tankards. We have successfully extracted shape features from these marks and matched master-marks in the database against the unknown query images. Initial experiments on master-marks are encouraging. The same shape-based matching techniques are used to match city-marks. Our future work will involve building an expert system for a stylistic analysis of the silver tankards Interesting, no?

IJP Posts: 326 Registered: Oct 2004	posted 05-28-2006 09:15 PM Very clever, and perhaps it would cut down on the hours I might spend with my nose in books, but it would eliminate one often advantageous side-effect of having to manually research marks... Say I'm trying to track down the identity of a particular maker, and in poring through the pages of a reference book, I stumble across a familiar mark; I pull out some of the long-forgotten mystery pieces I've been wondering about, and voilà, there's the mark I accidentally encountered while trying to research the first unidentified maker. This wouldn't happen with software that automates the search. So much interesting knowledge is discovered accidentally when you do things the long way. I find that most decent makers' mark identification references are well-enough organized that it shouldn't really take so long anyhow to find what you are looking for. A program that does the work for you could be highly convenient, but as for me, I think I'll be sticking to my books when I can. IP: Logged
