ACKNOWLEDGEMENT
This thesis would have remained a dream had it not been for Allah who has
made me being well. I want to grant this dream to the 25th January martyrs, who paid
their lives for our country Egypt, irrigating its lands with their blood to allow us reap
the fruits of freedom, equality and social justice.
It is with immense gratitude that I acknowledge the support and help of Prof.
Dr. Mostafa Abd EI-Aziem Mostafa. I consider it an honor to work with him. This
thesis would not have been possible had it not been for the guidance and patience of my
advisor Assoc. Prof. Dr. Gouda Ismail. Without his insights, feedbacks, and
encouragement, this thesis would not have been a success. I share the credit of my work
with Eng. Mohammed Seyam, assistant lecturer in Infonnation Systems department,
Faculty of Computers and Infonnation, Mansoura University.
I am indebted to my parents, my family, my friends and my classmates for their
emotional support. They have shown the greatest care and patience which I truly
appreciate.

Abstract
Photographers have been developed to be small and equipped with a focus.
However, they suffer from limited lens capabilities. Objects, in multi-focus images for
the same scene, lie in different depths. Capturing such images will make some of these
objects focused while the others are out of focus or blurred. Acquiring images that
contain objects at different distances in focus requires advanced hardware capabilities.
lIDs makes people take many images of the same scene in different focuses to get all
objects in focus. lIDs leads to the terminology Image Fusion, which extracts
perceptibly clearer images from a set of distorted images of the same scene. The fused
image contains common features and important information in all input images without
noise.
lIDs thesis compares six algorithms, which are Simple Average, spatial pixel
base algorithm, Discrete Wavelet Transform with four different fusion rules, multi scale
decomposition pixel-based algorithms, and Spatial Frequency, region-based algorithm.
Utilizing two measurements, which are the mutual information (MI) and the mean and
standard deviation (SO), the Spatial Frequency image fusion algorithm is the superior
of the six compared algorithms. The differences between these algorithms in the MI are
up to about 3.6%, almost the same, 0.44%, 1.03% and 0.45, respectively, and in the SO
up to about 13.07%, almost the same, almost the same, 0.28% and 0.14%, respectively.
This thesis introduces a novel algorithm for multi-focus single-sensor image
fusion based on complexity measurements. The main idea is to convert each N-bit input
image into N binary images and then divide these binary images into a set of blocks.
Then, using one complexity measurement, weights are given for each block in each
binary image of each input image. Finally, the fmal fused image is acquired according
to these weights. The proposed algorithm utilizes five complexity measurements, which
are: Length of Black and White Border, Run-Length Irregularity, Border Noisiness,
Transition Density and 4-Connectivity.

Utilizing the same two quality measurements, which are Mutual Information
(Ml) and Mean and Standard Deviation (SD), the results show that the proposed
algorithm using Length of Black and White Border and the 4-Connectivity complexity
measurements are almost the same or better than the Spatial Frequency image fusion
algorithm. These algorithms are better than the Border Noisiness in the Ml and SD up
to about 0.74% and 2.95%, respectively. The differences between the Border Noisiness,
Transition Density and the Run Length Irregularity in the MI up to about 0.91 % and
0.31 %, respectively, and in the SD up to about 1.24% and 0.57%, respectively.
