Our earlier work [1] [2] shows interesting characteristics of transmission range/power of the MANET nodes on the performance of multipath MANET routing protocol. The objective of this work is to improve the performance of a MANET multi-path routing protocol without increasing or decreasing its default transmission range of the nodes. The proposed work is to control the routing process and only allow...
In pervasive environment various devices with varying medium of access, mobility and connectivity have different types of services available among themselves. We are in need of a computing scheme which can utilize this limited amount of resources in the network in an efficient way. In this paper, we have considered various aspects of routing to find out the most efficient devices for service provisioning...
This paper proposes a messy model based watermarking scheme for the authentication of medical images. The digital fundus images are one particular class of medical images which has been chosen for simulation and analysis of the proposed scheme in this paper. These images are given in TIF format in RGB color space. The proposed scheme dynamically generates the watermark using messy models. And, it...
Combined discrete wavelet transform-fan beam transform (DWT-FBT) has been explored as a new possible domain for colour image watermarking. The two schemes proposed in the combined domain are (i) wavelet fan beam watermarking on luminance and chrominance and (ii) wavelet fan beam watermarking on chrominance alone. After the application of DWT on the host image and after careful selection of the suitable...
In the healthcare sector quality demands are rising for designing expert systems for medical diagnosis. At the same time growing capture of biological, clinical, administrative data and integration of distributed and heterogeneous databases create a completely new base for medical quality and cost management. Against this background we applied intelligent data mining methods for analyzing medical...
In this paper, we propose a novel face recognition method based on local appearance feature extraction using dual-tree complex wavelet transform (DT-CWT). It provides a local multiscale description of images with good directional selectivity and invariance to shifts and in-plane rotations. In the dual-tree implementation, two parallel discrete wavelet transform (DWT) with different lowpass and highpass...
