[ome-users] CBIR systems in Matlab

[Tom Macura]

GuangHui,

I don't know of any CBIR systems implemented in MATLAB either,  
although our classification work has much in common with CBIR.

We convert (in MATLAB) an image into a vector (about 800 values) in  
order to extract numerical content descriptors for supervised machine  
learning. The same features could be used in a CBIR system, however  
you will have to define the distance metric (based on your  
application, I'm sure).

The feature extraction code is open-sourced and available here:

2Fmatlab%2FOME%2F
