The German Traffic Sign Recognition Benchmark
**********************************************

This archive contains the training set of the 
"German Traffic Sign Recognition Benchmark".

This training set is supposed be used for the online competition 
as part of the IJCNN 2011 competition. It is a subset of the final
training set that will be published after the online competition is
closed. 


**********************************************
Archive content
**********************************************
This archive contains the following structure:

There is one directory for each of the 43 classes (0000 - 00043).
Each directory contains the corresponding training images and one 
text file with annotations, eg. GT-00000.csv. 


**********************************************
Image format and naming
**********************************************
The images are PPM images (RGB color). Files are numbered in two parts:

   XXXXX_YYYYY.ppm

The first part, XXXXX, represents the track number. All images of one class 
with identical track numbers originate from one single physical traffic sign.
The second part, YYYYY, is a running number within the track. The temporal order
of the images is preserved.


**********************************************
Annotation format
**********************************************

The annotations are stored in CSV format (field separator
is ";" (semicolon) ). The annotations contain meta information 
about the image and the class id.


In detail, the annotations provide the following fields:

Filename        - Image file the following information applies to
Width, Height   - Dimensions of the image
Roi.x1,Roi.y1,
Roi.x2,Roi.y2   - Location of the sign within the image
		  (Images contain a border around the actual sign
                  of 10 percent of the sign size, at least 5 pixel)
ClassId         - The class of the traffic sign
