    HOG features


    The file contains three sets of differently configured HOG features (Histograms of Oriented Gradients). The sets contain feature vectors of length 1568, 1568, and 2916 respectively. The features were calculated using the source code fromhttp://pascal.inrialpes.fr/soft/olt/. For detailed information on HOG, we refer to

    N. Dalal and B. Triggs. Histograms of Oriented Gradients for Human Detection. IEEE Conference on Computer Vision and Pattern Recognition, pages 886-893, 2005

    Haar-like features


    The file contains one set of Haar-like features. For each image, 5 different types of Haar-like features were computed in different sizes for a total of 12 different features. The overall feature vector contains 11,584 features.

     

    Hue Histograms


    For each image in the training set, the file contains a 256-bin histogram of hue values (HSV color space).

     

     

    Code snippets


    Matlab


    The Matlab example code provides functions to iterate over the datasets (both training and test) to read the images and the corresponding annotations.
    Locations where you can easiliy hook in your training or classification method are marked in the code by dummy function calls.
    Please have a look at the file Readme.txt in the ZIP file for more details

     

    C++


    The C++ example code demonstrates how to to train a linear classifier (LDA) using theShark machine learning library.
    This code uses the precalculated features. It was used to generate the baseline results.
    Please have a look at the file Readme.txt in the ZIP file for more details

     

    Python


    The Python example code provides a function to iterate over the training set to read the images and the corresponding class id.
    The code depends on matplotlib. Please have a look at the fileReadme.txt in the ZIP file for more details

    Result Analysis Application

    We provide a simple application to facilitate result analysis. It allows you to compare different approaches, analyse the confusion matices and inspect which images were classified correctly.
    The software is supplied under GPLv2. It depends on Qt 4.7, which is available here in source code and binary form. Qt is licensed under LGPL. Qt is a trademark of Nokia Corporation.

    The software is provided as source code and Win32 binary. The files can be found in thedownload section. The code is platform-independent, however, it has only been tested on Microsoft Windows with Visual Studio. So there might be a couple of issues left where GCC is more strict than Visual Studio. We appreciate any comments, patches and bug reports.

    The project uses CMake, an open-source, cross-platform build system which allows you to generate project files/makefiles for your preferred compiler toolchain.

    Here are some screenshots to get an idea of this tool.

    Training dataset


    This is the official GTSRB training set. If you either intend to participate in the final competition session at IJCNN 2011 or you want to publish experimental results based on GTRSB data, you must use this dataset for training.


    The training data set contains 39,209 training images in 43 classes.

    Test dataset


    Thís is the official GTSRB test set. It was first published at IJCNN 2011 during the special session "Traffic Sign Recognition for Machine Learning". All experimental results that are reported on GTSRB data must use this dataset for testing (apart from the ones already published at IJCNN 2011). The structure of the dataset follows the test set that was published for the online competition (and is now part of the training data).

    The test dataset contains 12,630 test images or the corresponding pre-calculated features in random order.
