is adopted. To decide the edge, we consider 12 directional differences, from D1 to D12 , as shown in Fig. 3. Only those composed of noise-free pixels are taken into account to avoid possible misdetection. If a bit in B is equal to 1, it means that the pixel related to the binary flag is suspected to be a noisy pixel. Directions passing through the suspected pixels are discarded to reduce misdetection. In each condition, at most four directions are chosen for low-cost hardware implementation. If
there appear over four directions, only four of them are chose accordingt..................[:=> Show Contents <=:]

proposed by Nisha Mary Mathew and K. A. Navas a novel blind reversible data hiding algorithm in medical images based on non sub sampled contourlet transform is proposed. It has the advantages of high capacity, imperceptibility and robustness.

The advantages of contourlet transform over other transforms (wavelet & DCT)have been discussed by Minh N Do & Vetterli.

INTRODUCTION

Biometrics based personal identification is getting wide acceptance in the networked society, replacing passwords and keys due to its reliability, uniqueness and the ever in-creasing demand of security. Common modalities being used are fingerprint and face but for face authentication people are still working with the problem of pose and illu-mination invariance where as fingerprint does not have a good psychological effect on the user because of its wide use in crime investigations. If any biometric modality is to succeed in..................[:=> Show Contents <=:]

ABSTRACT

In this paper, a simple and effective fractal-based simultaneous image denoising and interpolation scheme is proposed and implemented. The denoising is performed during the fractal encoding process while the interpolation is performed during the decoding process. The fractal-based image denoising involves predicting the fractal code of the original noiseless image from the statistics ..................[:=> Show Contents <=:]
