i want ppt of the project qr code watermarking algorithm based on wavelet transform for my main project

Today, as the digitization develops day by day, the protection
of digital information becomes an urgent problem.
In order to resist different kinds of infringement, a new
technology that called watermarking had been put forward
to in the international scope. Watermark is sequence
carrying information about the copyright owner
to embed into the digital image [1], audios and videos in
order that owners can read it out while unauthorized users
cannot1 easily remove it.
There are many methods to embed the watermark. It
can be divided into two classes: spatial-domain watermarks
and transform-domain watermarks. The spatial
domain is so simple that the watermark can be damaged
easily, but the transform-domain algorithm can be resist
intensity attack, watermark information can’t be damaged
easily. The transform algorithm includes chiefly
DWT, DFT and DCT[2,3,4]. Wavelet transform is superior
to time-frequency transform for its inner predominance.
For example, wavelet has the character of
multi-resolution, which can avoid the rectangle brought
by DCT. In fact, it has more application fields in engineering
and computer science. In this paper, a new blind
watermarking algorithm that embeds a meaningful binary
image into the color images is proposed based HT-DWT
according to HT and DWT characteristics.
The rest of the paper is organized as follows. Section 2
introduces the hadamard transform and discrete wavelet
transforms analysis in briefly. In section 3, a new blind
watermark algorithm for color image based HT-DWT
domain is presented in detail. Experimental results are
described in section 4. Finally, in section 5 the conclusion
is given.
