Abstract

Fingerprints are claimed to be both unique and permanent, making it an ideal biometric trait for person identification in. Fingerprint images generally contain either a single fingerprint or a set of non overlapped fingerprints. However, there are situations where several fingerprints overlap on top of each other. Overlapped images are mainly encountered in latent fingerprints lifted from crime scenes. Overlapping may also occur in lives can fingerprint images when the surface of fingerprint sensors contains the residue of fingerprints of previous users. In this paper, we propose a novel algorithm to separate overlapped fingerprints into component or individual fingerprints and evaluate it using both real overlapped latent fingerprints. The proposed method involves two basic assumptions which involve overlapped fingerprint is combination of two fingers and two fingerprints has different orientation. It first estimate the orientation field of the given image with overlapped fingerprints and then separates it into component orientation field using a relaxation labeling technique. Most Automatic Fingerprint Identification Systems (AFIS) use some form of image enhancement. Once the Finger print was extracted Gabor filtered can be used to enhance the quality of extracted image.

Abstract

The systems engineers designing Personal Communication Products face issues that require a new approach to solve the balance act between end user perceived (GUI) performance and unnecessary applications developed on their products. In this paper we approach a new trend in designing personal communication devices. The hardware is based on a 32-bit Embedded microprocessor with low-power and high performance S3C2440A, the real-time operating system is Windows CE 6.0,is used to complete the work of programming. This paper mainly introduce concept of designing unique OS and unique application development to the individual customer based on the WinCE embedded operating system which will bring a new revolution in international markets.

Keywords

Abstract

The WiMAX Forum supports various scheduling algorithms to identify and classify the heterogeneous traffics. But the scheduling algorithm alone will not achieve the better quality of service in Mobile WiMAX IEEE 802.16e. The call admission control plays an important role especially when combined with scheduling service, as they are intended to manage and guarantee the QoS requirements. Hence we are proposing the Gateway Relocation Call Admission Control (GRAC) algorithm, it just accepts or rejects the Mobile Stations and Priority based scheduling algorithm differentiates the mobile stations with good channel conditions from  poor channel conditions, and to differentiate real-time traffics with the non-real-time traffics. For this reason, the network delay reduced while the throughput of a network can be improved compare to implementing one of them alone. In addition, our algorithm implementation also keeps fairness in mind, which diminishes the starvation of non-real-time traffics. Simulation result shows the increase the network performance in terms of throughput; maintain the long-term fairness, and low packet dropping and blocking ratios of real-time traffics.
