Preliminary, but at least we can conclude that the colors are diverse, and that black-on-white is rather common. I hope to be able to detect and read these eventually, but I'll have to come up with something better than the current color-histogram matching technique. :) - Tijs On Wed, Aug 19, 2009 at 7:30 AM, Teemu Koskinen teemu.koski...@mbnet.fiwrote: On Wed, 19 Aug 2009 14:26:29 +0300, Erik Johansson e...@kth.se wrote: Since this version can't be trained to handle white background signs, I wonder what color are streetname signs around the world?

Perhaps would be a good idea to set up a wiki page for the signs with the colors and a sample photo? Here in Rio de Janeiro, Brazil they're a rectangle with the street name in white on blue, and a blue on white stripe with the first and last building numbers of the block and the street's postcode (which are not like zip codes, they're different for every single street).

Not to mention the habit of some municipalities here to clarify the name of the street on a separate line. Or what about Belgian bilingual signs, with a creative Rue actual name Straat system, cleverly making use of the fact that in French the 'street' word goes at the beginning and in Dutch it goes at the end. building numbers of the block and the street's postcode (which are not like zip codes, they're different for every single street).

here, whatever the local council decides to put up often reflective silverish background, black letters may be black on yellow may be white on blue may be green on white Where's here? The UK seems to be rather variable, black on white is most common but I've seen white on green, white on black, and rarely, other schemes such as white on blue. The UK seems to be particularly heterogeneous with regards to colour and font compared to other countries I've visited such as Germany and the USA. Other countries have more tendency for a national scheme, whereas the UK seems to depend on the local council, and even they are inconsistent (my own city has about 10 to 15 different styles, some introduced within a few months of each other!)

In Massachusetts, US, street sign coloring can vary at each town (where there are ~350 towns, many of which have ~ afew thousand people). There are a lot of white on green (my town), but the next town west has white on red. Plus, the town I grew up has black raised lettering on white with a black border (think pretty wrought iron) for old signs, but I think is replacing them with white on green. I would think the solution is an easy way to train/teach, not a giant database of the world, as it seems too variable in time to keep up with at that scale. pgp652sJyUrYr.pgp Description: PGP signature ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Hey All, As of yesterday, the Google Summer of Code has ended. With some appropriate pride, I offer you signFinder: http://code.google.com/p/signfinder/ . As part of the OpenStreetPhoto project, this program detects, segments, and reads dutch street-signs. For high-quality pictures (and not too old street-signs), performance is good. The project is right now trained to read dutch street-signs, but as long as they have a distinct color, there's no reason why it couldn't read foreign street-signs. Read this: http://code.google.com/p/signfinder/wiki/TrainingOtherCountries document on how to adapt the signFinder to street-signs of other countries. The end of the summer of code, doesn't mean that I'll stop working on this project. There are still methods to explore, and performance to improve. More importantly: I'm looking for practical applications for this software. I'll be working with Stefan and others on an integration with the OpenStreetView / OpenStreetPhoto project, but suggestions on an exact use are welcome, as well as wholly unrelated ideas. I just saw that a discussion going on about video in OpenStreetView. I expect to have a video to play with soon, and will report if results are reasonable. - Tijs ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
