We been spotted :)

Thursday, March 13th, 2008

Dave Pattern up in Huddersfield has reminded me that he has already done some work on identifying colours in book jackets and then retrieving them to good effect.  Now I have been prompted, I vaguely remember having looked at Dave’s work.  Yet when Richard suggested we could do something interesting with book jackets… nope… blank… Thanks dave for reminding me!  I see also that Ed Vielmetti has spotted us at work…  Ed, a bit of the back story can be found on the Colourphon Wiki ;) .

Of course this little project is in very early days – we are not even storing anything yet!! – so come back later and see how we are getting on.  And of course, If you have any ideas or things that you think might be rather cool applications – let us know, either here, or on the aforementioned Wiki.

Exif captured from jpg images

Saturday, March 8th, 2008

Tonight I added support for Exif data capture from the image (if it is a JPEG). We will need to map this to something useful, but I have already found a schema and a potential description vocabulary.

Try this example.

Weighted colour matches

Thursday, March 6th, 2008

We were figuring that it might be useful to have a colour match that was in some way relevancey ranked, so I have been working on ways to achieve this.

What we have now is a result set that is sorted according to the position of the frequent colours in the image.  We also know where each cell is in the image, and can calulate – at it’s simplest – a sort order based on centre weighting.

Need an example?  These examples will take a moment or two to calculate…

Try this one: Test number one.
Or this one: Test number two.

We divide the image into an odd number of cells, ensuring that there is one in the middle. We then scan each cell and analyse the colour content.  Then we give you the results.

Simple yet strangely satisfying, and not only that, but you can analyse an image from any source, be it File, URL or book jacket retrieved by isbn search courtesy of the Talis Platform.
