Matlab MPEG 7 descriptors

Question

Hello, I need some descriptors of MPEG7 in Matlab. The descriptors are dominant color, color layout, color structure, scalable color, edge histogram and homogeneous texture. Do you know where can I find Matlab source code for these descriptors?

Thanks

Answer 1

Can you extract the descriptors from the MPEG7 file using ExifTool?

If you can, and you're using Windows, then it's possible to run Exiftool from Matlab using the dos command. The result from the dos command contains the output of Exiftool as text which you can parse to get the descriptors you require.

If you can find a Java tool that does the trick, then accessing it via Matlab is possible (I've got this to work for a few things, but I'm not clear how it works!)

I get the impression that MPEG7 is an XML based format - there are a number of ways of parsing XML using Matlab...

I couldn't quickly find any MPEG7 files to try these routes out...
