Real-time traffic sign detection using Gielis curves

System & dependencies

System requirements:

• Ubuntu 14.04
• CMake 2.8.12
• Eigen 3.2.0
• OpenCV 2.4.8
• GTest 1.6.0

CMake Library

sudo apt-get install cmake

The version available in Ubuntu 14.04 repositories is CMake 3.2.2

Eigen Library

sudo apt-get install libeigen3-dev

The version available in Ubuntu 14.04 repositories is Eigen 3.2.0

OpenCV Library

sudo apt-get install libopencv-dev

The version available in Ubuntu 14.04 repositories is OpenCV 2.4.8

Google tests

sudo apt-get install libgtest-dev

The version available in Ubuntu 14.04 repositories is GTest 1.6.0

However, this command only downloads the source that you need to compile.

cd /usr/src/gtest
sudo cmake CMakeLists.txt
sudo make

# copy or symlink libgtest.a and libgtest_main.a to your /usr/lib folder
sudo cp *.a /usr/lib

The version available in Ubuntu 14.04 repositories is GTest 1.6.1

Compilation

• Create a build folder:

mkdir build

• Move to the created folder:

cd build

• Create the MakeFile via cmake:

cmake ../src

• Compile the code to generate the executable:

make or make -j n where n is the number of cores to use for the compilation

• A folder bin will be created at the same level as the build directory.

• In order to run the code:

../bin/main ../test-images/different0035.jpg

traffic-sign-detection's Issues

How to make it real-time and for video?

Awesome work! Here are several concerns from my using.

First, it said that the program runs in real-time. However, I run the sample test as the Readme said:
"../bin/main ../test-images/different0035.jpg"
but got a really long time to run:
"Elapsed time: 9864.11 ms"
Do you know how I can make it run in real-time?

Second, for real-time, it should be running on video or a webcam. Do you have any suggestions or code for video testing?

Thank you so much!

Make error

I'm getting this error when I try to run make. Any ideas why?

make:** No targets specified and no makefile found. Stop.
I'm running Mint 18
Any ideas why?

Thanks.

vector<vector<Point>> and vector<Point>

Dear Sir,

I would like to ask what is the difference between the two statements:

vector<vector<Point>> contour;
vector<Point> contour;

Thanks

find_package(OpenCV REQUIRED)

Can anyone with OpenCV 2.x confirm that
find_package(OpenCV REQUIRED core highgui imgproc features2d calib3d)
instead of
find_package(OpenCV 2.4.8 REQUIRED core highgui imgproc features2d calib3d)
works for them, in /src/cmake/findDependencies.cmake?

Research Paper needed

Do you have any research paper or any article so that understanding code will be easy ?

make error for undefined references

Nice work! But one point is that I followed the installation for traffic-sign-detection and got a make error in the final step as follows.

Do you have any suggestions for what might be the reason of the error? Thank you so much!

Bug found when fitting triangular signs in develop branch

There is a bug that has been introduce between the master branch and the develop branch.
It affects mainly the triangular signs. I would expect something inside SuperFormula.cpp file

Segmentation fault (core dumped)

Hi,
I am experiencing "Segmentation fault (core dumped)" on all input images.
I am beginner to the C++ (came from Java and Python) thus can't provide stack trace or whatever is equivalent in C++. However, by using std::cout I found that root source is in imageProcessing.cpp

cv::convertPointsToHomogeneous(contour, homogeneous_contour);

I am running on Ubuntu 16, Open CV 3.1.0. Compiled your code by make and in the QtCreator.
Both ways failed.
Describe me what information you do need for the analysis and how to get it.
I am more then interesting in your project.

log chromatic format

// Function to convert an RGB image (uchar) to log chromatic format (double)
void rgb_to_log_rb(const cv::Mat& rgbImage, std::vector< cv::Mat >& log_chromatic_image) {}

Could you tell me what the purpose of this funciton?And what is the log chromatic format ? I can not find any information about this .Thank you!
