We propose a novel fast inverse halftoning technique using a combination of spatial varying filtering and spatial invariant filtering. The proposed algorithm is significantly simp...

The SOVA and the log-MAP are commonly used in turbo decoding. In this paper, we propose to modify the sliding window MAP-algorithm in [5]to reduce the computational delay even fur...
This paper describes a high performance CMOS differential input front-end, designed for optical wireless communications. The front-end achieves a 50 MHz bandwidth and a 400 K tran...

This paper addresses the problem of bit-rate conversion of a previously compressed video. We provide an MPEG joint transcoder for transcoding several video bitstreams simultaneous...
MPEG-4 video consists of various video objects, rather than frames, allowing a true interactivity and manipulation of separate arbitrary shape object. Soware-based encoding of MPE...
