PHOG bins with zero values

[GoogleCodeExporter]

Sometimes I've got phog bins with zero values. I don't know if it is an error 
in phog descriptor or not. 

I'm using chi-square distance to measure the distance between two phog feature 
vectors. Since this metric doesn't allow bins with zero values, it results with 
error.

I attach an image (28.jpg) which I got this behaviour (phog.txt, see 24th bin). 
Phog parameters are the deafults: bins=8 and recursions=1 

I used the Extractor utility to extract phog features. My command line: java 
-cp JfeatureLib.jar de.lmu.dbs.jfeaturelib.utils.Extractor -D PHOG -c c -d 
/home/patricia/imgs/ -o phog.txt

Best regards,
Patricia
