The importance of watermarking digital databases has increased by leaps and bounds due to the high vulnerability of digital assets to piracy attempts when they traverse through the internet. To deter piracy, we propose a robust watermarking scheme for rel... see more


This article discusses linear complementary dual (LCD) codes over R = Fq+uFq(u2=1) where q is a power of an odd prime p. Authors come up with a new Gray map from Rn to F2nq and define a new class of codes obtained as the gray image of const... see more

A new technique for detecting the high density impulse noise from corrupted images using Fuzzy C-means algorithm is proposed. The algorithm is iterative in nature and preserves more image details in high noise environment. Fuzzy C-means is initially used ... see more

High dynamic range images contain both the underexposed and the overexposed regions. The enhancement of the underexposed and the overexposed regions is the main concern of this paper. Two new transformation functions are proposed to modify the fuzzy membe... see more
