Batch mode Processing of images

[swapnil barai]

Hi

I have got FIRE's upload feature working, and it gives the images
similar to the uploaded image as the result.

However if I have a test-dataset of say 500 images, manually uploading
each image on the interface of FIRE and checking for results is very
inefficient. If I Just want to do it using a script, can someone give
me a idea on how to go about tweaking the code of 'fire.py' (or other
files if required).

Would appreciate your help.

Thanks
Swapnil

Dear Swapnil,

The fire distribution contains a few example scripts for batch processing.

e.g. querylist.py

these should allow you to customize everything quite easily.

One option to learn about the capabilities is to telnet into fire:

say your FIRE server (not the webserver) is running on port 12960 (default)
then you do

telnet localhost 12869

then type help


then type random

then copy one of the filenames and type

retrieve <copied filename>

and so on.

@Thomas

Thanks, querylist.py was the perfect thing that I was looking for.

However one thing I found was, that the result for a particular image through the graphical interface and through the script querylist.py vary a bit. What is the reason for this? Can this be resolved?

Thanks
Swapnil

I cannot see how this can happen, unless you use some of the
non-documented randomized feature extractation (which I am not even
sure it is still in FIRE).

I rather guess, that there is a difference between the configuration
of the server for these two cases or are you using the same server?

Actually I use the same server for both querylist.py and the graphical interface.

I start the fire sever in one terminal window.

Then in another terminal window I run the querylist.py.

At the same time I also open a browser window and access fire's graphical interface and give an image as input.

However the results tend to differ partially.

This is strange and should not happen.

Can you please try to create a reproducible example?

fire.py puts a comment into the first few rows of the generated html
displaying the result... similar to that:

e.g. If you use this url:

http://www-i6.informatik.rwth-aachen.de/~deselaers/cgi_bin/fire.cgi?queryImage=images/427.jpg

This will show up in the HTML:

<!-- ['images/427.jpg', '1', 'images/460.jpg', '0.803545',
'images/420.jpg', '0.734208', 'images/481.jpg', '0.730597',
'images/401.jpg', '0.641704', 'images/413.jpg', '0.640427',
'images/474.jpg', '0.629051', 'images/467.jpg', '0.618669',
'images/447.jpg', '0.60276', 'images/418.jpg', '0.601587']-->

These values should be compared to the output of querylist.py.







Cheers,
thomas
