Face is considered to be one of the biometrics in automatic person identification. For face recognition system to be practical, it should be robust to variations in illumination, pose and expression as humans recognize faces irrespective of all these variations. In this paper, we present an illumination invariant face recognition method in the logarithm discrete cosine transform domain. We use an...
All public key cryptosystems, though being highly secure, have a common drawback: They require heavy computational effort. This is due to the reliance on modular multiplication of large operands (1024 bits or higher). The same problem arises in data encryption/decryption and digital signature schemes. Examples of such cryptosystems are RSA, DSA, and ECC. Now considering embedded platforms for applications...
The aim of this paper is to introduce the implementation of a MAC protocol on a Load-balanced short-path routing algorithm [1], and to show the effect of the MAC requirements on the behavior of the protocol. This work provides an estimate of how might the overhead introduced by the MAC protocol affect the behavior of the routing algorithm, i.e. how it would affect the load on the nodes of the network...
This paper proposes an enhancement to a novel end-to-end QoS framework that has been recently introduced in the literature and referred to as the on demand QoS path (ODP). The ODP provides the end-to-end QoS guaranty of the integrated service (IntServ) while keeping the scalability nature of the differentiated service (DiffServ). The proposed enhancement, named E-ODP, efficiently reconfigures network...
