Computer Vision: Real-time Pattern Recognition using C++

The algorithm recognizes patterns that are printed on a white sheet of paper. To detect the paper, it has to be placed on a darker background. It is possible to recognize over 100 different patterns. The steps of the algorithm include adaptive thresholding, detecting contours, histogram normalization and template matching. The algorithm is programmed in C++ and runs in real-time, using only a few milliseconds per frame. It is thus also applicable on embedded systems and cell phones.

where is the source code?

[x3n1337]

@ihmc3jn09hk Hi, it's part of the ai_vision code repository of the PIXHAWK project at pixhawk.ethz.ch

I don't know if the repository is open for public, but you can try and ask them.

Hey thats cool ! Did you base it on OpenCV or was it a custom code ?

[x3n1337]

@atirthah Hi, thanks! Yes, the code is based on OpenCV, but doesn't solely use OpenCV's functions. About 50% of the algorithm is custom-made. However one could likely use more of OpenCV's functions, but I tried to obtain maximum performance and full control of the code.

@x3n1337 Hi, can you send your source code for me via email(andyvebby@gmail.com)?. your video is very good.i'm an student and i want to study image processing.thanks

[nvramarajur1]

i am doing a project based on image recognisation so this code very useful to us

can you send that source code for me

[nvramarajur1]

this vedio is very good and it is very use ful
