DWT Based Blind Digital Video Watermarking Scheme for
Video Authentication


INTRODUCTION

Video is a three-dimensional array of color pixels. Two
dimensions serve as spatial (horizontal and vertical) directions of
the moving pictures, and one dimension represents the time
domain . Digital video offers a number of advantages over
analog video, including the ease of sharing and storage, no
degradation of data quality when replicated, easy and inexpensive
copying and the capa ....etc

Principle Component Analysis PCA is a classical feature extraction and data representation technique
widely used in pattern recognition. It is one of the most successful techniques in face recognition. But it has
drawback of high computational especially for big size database. This paper conducts a study to optimize
the time complexity of PCA (eigenfaces) that does not affects the recognition performance. The authors
minimize the participated eigenvectors which consequently decreases the computational time. A
comparison is done to compare ....etc

Plz, help me with the PCA code for doing image fusion. i need the program with an example. i tried for cameraman image but getting the output as complete black. i blurred it at two different places so i hav i1 n i2 which are blurred images which i converted to zero mean images i_1 n i_2.This is my program. what to do next?

clc;
close all;
clear all;
f1=imread('cameraman.tif');
figure(1);
imshow(f1);
=size(f1);
f1=im2double(f1);
level=input('enter the level of blur');
degradation=fspecial('average',);
i1=f1;
....etc
