In this paper, we propose an algorithm called Optimum Intensity Based Distributed Hiding (OIBDH) for secret data hiding inside cover images. The algorithm is a modified version of Bit Plane Splicing LSB technique with better hidden capacity and improved embedding process. The proposed algorithm outperforms Bit Plane Splicing LSB technique as more data can(More)
A benign chondroblastoma of the temporal bone in an 8-year-old boy is reported. Head CT showed an expansile mass with calcifications in the center. The tumor appeared as a well-lobulated, hypointense intraosseous mass on T1-weighted brain MR; it was isointense to brain parenchyma on intermediate-weighted images and enhanced homogenously with gadolinium.
In the current paper, we have presented a novel watermarking scheme with making watermark as robust while keeping the image fragile using Residue Number System (RNS) and Chaos. Residues of the image are made to keep it secure since, their sensitive to change is high. Only Region Of Interest (ROI) part of the image is residued. In making residues of ROI,(More)
Adaptive Resource Allocation is a prominent and necessary feature of almost all future communication systems. The transmission parameters like power, code rate and modulation scheme are adapted according to the varying channel conditions so that throughput of the OFDM system may be maximized while satisfying certain constraints like Bit Error Rate (BET) and(More)
