Template matching is a technique for finding small parts of an image which match a template image. Download this example on how to perform template matching with OpenCV. Read more
If you have a webcam attached to your computer, you can display video stream using OpenCV easily. Here's the basic code. Read more
Using FFTW to perform FFT operation in OpenCV is a good choice. This is an example on how to use FFTW with OpenCV. It simply loads an image, compute FFT & IFFT, then display the final result. The resulted image has no difference with the original, as it should. Read more
FFTW is a collection of C routines for computing DFTs. It's very fast and freely available at http://www.fftw.org. Here's an example on how to compute the DFT of an array with FFTW and inverse the result back. Read more
A simple program that displays live video from a webcam and tracks user's eye. The system tracks user's eye with a given template, which was manually selected using mouse. Read more
