Hi Aymen,

[there is a FIRE mailinglist, which I added to the reply. Please use this mailinglist for any further questions or I may not respond to it].

Sounds like your image is stored in a format that the FIRE jpeg reading routines don't understand. 

Maybe you could try to convert it to another color space and retry?

The imagemagick tools should allow for a very easy conversion.

Cheers,

thomas

Hello Thomas,

I'm working on images indexing and retrieving on similarity based search. I've tried to install  the Flexible Image Retrieval Engine on an ubuntu machine (https://code.google.com/p/fire-cbir/).

When i tried to do the histogram color extraction, it gave this error : 

(10) [FeatureExtractors/extractcolorhistogram.cpp:93:main] Processing '/home/loukil/images/143_0071.jpg' (1/101). [Features/imagefeature.cpp:136:load] ERROR: Unknown color space13

Could you please help me ?

Thank you in advance

Regards 

Aymen

Hi,
I had the same problem as you, I replaced : in    Features/imagefeature.cpp:136:

if(loaded.colorSpace()==RGBColorspace && !forceGray) {
    zsize_=3;
    DBG(30) << "found image in RGB" << endl;
  } else if ( loaded.colorSpace()==GRAYColorspace || forceGray) {
    DBG(30) << "found image in gray" << endl;
    zsize_=1;
  } else {


    ERR << "Unknown color space" << loaded.colorSpace() << endl; return false;

by

  zsize_=3;
  DBG(30) << "found image in RGB" << endl;

I forced to choose three, I had a correct histogram.

Youssef.
