Latest on what it will do…

Monday, January 14th, 2008

So we are pretty happy with the colour guessing now, although at this stage we are limited to a named palette of 254 colours.  Try it.

The guessing is based on a sample of the most frequently occurring 400 colours, that are then compared to each other to match those that are within 10%, then de-duplicated at the named colour stage.  This seems to give a fairly accurate representation of the main colours in the image.  Next stage is capturing that info in some sort of data model. So we are looking into the semantic web’s best friend RDF.

Learning …

Friday, January 11th, 2008

This week has been mostly about learning, although it is worth mentioning that we have got better at analysing a particular image, and you also get a best guess shade, and the colour that that shade belongs to.

A few of the blogs we follow brought up something related that could be very useful in the future of colourphon – namely this article about HTML imagemaps. Something like this could be used to give focus on the images that we analyse – meaning that a more accurate colour can be obtained – the development experiments have begun – but confined to localhost (I’m afraid).

Our main aim is to help build the semantic web with images – our focus on just getting the data at the moment, but with the potential of harvest and storage (RDF) in the future. We found this which really helped me understand some of the simpler parts of RDF (triples etc… I told you we were learning this week :D ).
