Figure 1. Embedding and Retrieval of the watermark
ABSTRACT
In this paper a novel algorithm based on wavelet transform is proposed for digital image watermarking. The algorithm is primarily combinations of TWT (discrete wavelet transform) and modified throsholding scheme to search exact coefficient for watermark embedding. The proposed algorithm gives good results of watermark retrieval also [...]

In this paper we presented a new image watermarking technique that can embed more number of watermark bits in the cover image without affecting the imperceptibility and increases the security of watermarks. To increase the embedding capacity the concept of watermark in watermark is used. Means it embeds an extra watermark into the main watermark [...]

FACE PROCESSING
SYSTEM –WAVELET AND
FSOFM ABSTRACT The
human face is one of the
most important patterns
our visual system receives.
It establishes a
person’s identity
and also plays a significant
role in everyday
communication. Humans
can recognize familiar faces
under varying lighting
conditions, different
scales, and even after the
face has changed due to
aging, hair style, glasses,
or facial hair. Our ease at
recognizing faces is a
strong motivation for
