This paper proposes a novel approach of combining an unsupervised clustering scheme called AutoClass with Hidden Markov Models (HMMs) to determine the traffic density state in a R...
In multi-camera networks rich visual data is provided both spatially and temporally. In this paper a method of human posture estimation is described incorporating the concept of a...
This paper presents a low-complexity, high-speed 4-dimensional 8-ary Phase Shift Keying Trellis Coded Modulation (4-D 8PSK TCM) decoder. In the design, an efficient architecture f...
Low-density parity-check (LDPC) codes on par with convolutional turbo codes (CTC) are two of the most powerful error correction codes known to perform very close to the Shannon li...
Belief propagation has become a popular technique for solving computer vision problems, such as stereo estimation and image denoising. However, it requires large memory and bandwi...
This paper describes the sub-Nyquist rate digital-to-analog conversion technique for a direct waveform synthesis (DWS) transmitter. IEEE 802.22 TV band Cognitive Radio (CR) transm...

In this paper, we present a bio-inspired unified model to improve the recognition accuracy of character recognition problems for CAPTCHA (Completely Automated Public Turing Test t...
The upcoming Reconfigurable Video Coding (RVC) standard from MPEG (ISO/IEC SC29WG11) defines a library of coding tools to specify existing or new compressed video formats and deco...

In this paper we present the VLSI implementation of a high-throughput enhanced Max-log-MAP processor that supports both single-binary (SB) and double-binary (DB) convolutional tur...
In 2004, ISO/IEC SC29 better known as MPEG started a new standard initiative aiming at facilitating the deployment of multi-format video codec design and to enable the possibility...
