This paper describes an optical flow estimation algorithm using directional filters and an AM-FM demodulation algorithm, and its efficient implementation on a NVIDIA GPU using CUDA. The resulting implementation is several thousand times faster than the corresponding MATLAB code, which makes the described scheme suitable for real-time applications. This(More)
A high performance low complexity algorithm for noise suppression in hearing aids, using spatial information for estimating the required noise and speech power spectral densities (PSDs), is proposed. The main assumption of the scheme is that the target is directly in front of the hearing aid user while the noise comes from the back hemisphere. Furthermore,(More)
