In this paper we propose an effective de-ringing method for DCT compressed images and videos. This method performs a subband decomposition provided by a translation invariant wavelet and processes only the high level subbands by means of a local adaptive equalization around the edges of the image. This makes the procedure suitable for both texture and flat(More)
Among all the techniques for 3D acquisition, stereo vision systems are the most common. More recently, Time-of-Flight (ToF) range cameras have been introduced. They allow real-time depth estimation in conditions where stereo does not work well. Unfortunately, ToF sensors still have a limited resolution (e.g., 200 × 200 pixels). The goal of this paper(More)
Block based recursive search for motion estimation is already suitable for real time applications thanks to its wide utilization, but the increase of resolution in modern displays and the need for real time software implementations demand for faster approaches. In this paper a new motion estimation procedure that has been developed for a parallel(More)
