In the field of face recognition, the major challenge that encountered classification algorithms, is to deal with the high dimensionality of the space representing data faces. Many methods have been used to solve the issue, our focus, in this paper, is to compare the efficiency (in the term of complexity and recognition rate) of linear and non linear(More)
VoIP is a promising technology that has been expected to be the future of voice telecommunications. Thus, with the increasingly widespread use of internet-enabled devices, the interest for speaker recognition systems over VoIP networks will be increased day by day. In this paper, we intend to analyze and investigate the relation between the amount of VoIP(More)
The aim of this paper is to evaluate, analyze and compare the performance of the most popular MFCC variants for features extraction in text-independent speaker identification over VoIP Networks. The MFCC variants were tested and evaluated under a Gaussian mixture model (GMM)-based speaker identification system, which represents the speaker modeling(More)
In this paper we propose a novel method to automatically detect the polyp's ROI (Region Of Interest) based on a Gaussian Mixture Model, Esperance Maximization algorithm segmentation, Hough transform and region growing. Our main objective through this work is to help in the early detection and precise analyze for the polyps diagnosis, which is a huge apport(More)
Over the past several years, the Mel-Frequency Cepstral Coefficients (MFCCs) has become the state-of-the-art approach for features extraction in text-independent speaker recognition applications. However, the recently introduced Gammatone Frequency Cepstral Coefficients (GFCC) has shown a promising recognition performance in such speaker recognition(More)
The automotive industry is working to develop the Dedicated Short-Range Communication (DSRC) technology. It is an emerging technique and key enabling technology to push the intelligent transportation system with safety applications into our daily life. The DSRC standards generally make use of FM0 and Manchester codes to have good dc-balance, enhancing the(More)
This paper describes a low-power (LP) programmable generator producing pseudorandom test patterns with desired toggling levels and enhanced fault coverage gradient compared with the best-to-date built-in-self-test(BIST)-based pseudorandom test pattern generators. It is comprised of a linear finite state machine driving an appropriate phase shifter, and it(More)
The purpose of this paper is to design and develop a MAC Transmitter on Field Programmable Gate Arrays (FPGA) that converts 32 bit data in to 4 bit DATA for transmitter. The data which is used for transmission is UDP Packet. The entire UDP packet will go as data for MAC frame. In this paper we design the Ethernet (IEEE 802.3) connection oriented LAN Medium(More)
Over the past several years, The Mel-Frequency Cepstral Coefficients (MFCCs) and Gaussian mixture models (GMMs) using the well-known EM algorithm have become the state-of-the-art approach in text-independent speaker recognition applications. However, in recent few years, Self-Organizing Mixture Models which combines the strengths of Self-Organizing Maps and(More)
