Digital Watermarking for Medical Images using Biorthogonal Wavelet Filters and Transformed Watermark Embedding

Using several mathematical models and equations, we have shown how to capture the concerned conflicting watermark security problem into a game theoretic model and we have

The proposed weighted fuzzy fisherface method using Biorthogonal wavelet transform for face recognition is superior to fuzzy fisherface method by having full

Watermarking in sequential circuits is a process of embedding watermark sequence detection states in the state transition graph (STG) which detect the

In this paper we propose a DWT based dual watermarking technique wherein both blind and non-blind algorithms are used for the copyright protection of the

Though a number of biorthogonal wavelets are proposed in the literature, in this paper four new biorthogonal wavelets are proposed which gives better compression

The entropy of the watermarked image and correlation coefficient of extracted watermark image is very close to ideal values, proving the correctness of proposed

In case of stereo audio signal, same watermark information or the meta data used during the embedding process (redundancy factor, length of.. watermark,

ABSTRACT : This paper presents simple and efficient method for text detection, extraction and localization from video or static images using Haar wavelet and
