Using the libraries pkmFFT and pkm::Mat, you can very easily perform a highly optimized short time fourier transform (STFT) with direct access to a floating-point based object.

Apple’s Accelerate Framework can really speed up your code without thinking too much. And it will also run on an iPhone. Even still, I did bang my head a few times trying to get a straightforward Real FFT and IFFT …
As part of a system of numerous dynamic connections and networks, we are reactive and deterministic to a complex system of cause and effect. The consequence of our actions upon our selves, the society we live in and the broader …
Over the past 2 years, I have been working under the direction of Prof John M Henderson together with Dr Tim J Smith and Dr Robin Hill on the DIEM project (Dynamic Images and Eye-Movements). Our project has focused on …
Taken from the changelog:
…New functionality, features: <<< – General:
* The brand-new C++ interface for most of OpenCV functionality
(cxcore, cv, highgui) has been introduced.
Generally it means that you will need to do less coding to achieve the same
In 2007, a very nice implementation of a variational implementation of optical flow was described in: A Duality Based Approach for Realtime TV-L1 Optical Flow by C. Zach et. al. I won’t get into the details too much, but …
