dc.description The accomplishment of my M.Sc. research and write-up of this thesis are the most memorable events in my life so far, which might not be possible without the support of my supervisor, colleagues, friends, and family. At the end of this MSc research, it is a pleasure to thank everybody, who has helped me all the way. First and foremost, I would like to thank my supervisor, Major Hussain Md. Abu Nyeem, PhD, EME, who has been a perfect mentor for me. I am grateful to him for giving me directions, confidence and valuable advice, and for everything that I have learned from him. He has had a tremendous impact on the way I perceive research and life in general. Major Nyeem has also been very helpful in many ways to me and for my research. His feedback from different critical angles has always been encouraging and useful. He also has taught me many practical aspects of research from the elementary level. Once again I thank my supervisor, with whom I feel that I genuinely have been privileged to work. I profoundly thank Professor Satya Prasad Majumder; Air Commodore Md Hossam-E-Haider, PhD, BAF and Colonel A K M Nazrul Islam, PhD for their valuable and constructive feedback, assistance and being on my final defense panel. I thank Major Md Tawfiq Amin, PhD, EME for kind coordination and cooperation as the postgraduate course coordinator. Also thanks to all the reviewers, for their appreciation and feedback on my thesis and publications. I am grateful to my colleagues and friends for making my working at MIST and BMA, more than comfortable and enjoyable. I express my gratitude for their suggestions and help to find a solution, technical or otherwise. I would be pleased to extend my sincere thanks to all of my course teachers and staffs of EECE department, MIST for their kind support. Special thanks to Captain Mahbub, Captain Shafiul and Mr. Hafizur Rahman for their cordial assistance and official support to complete the administrative procedures. I thank each member of my family, for being understanding and supportive. I am most thankful to my parents, for their invaluable encouragement. My mother, in spite of her sickness from the last two years, who always encourages me all the ways, I can not express my gratitude to her in words. Similarly, I could not find words that express my gratefulness to my wife Farhat Ferdous Bonny, for her supportive and understanding attitude. Many conversations, laughs and sweet memories with her helped take the pressure off during my stressful times. Furthermore, I would also like iv ACKNOWLEDGEMENTS to thank Mrs. Luisa Fozila Chowdhury, the spouse of my supervisor, for her endless patience during my working days and nights with my supervisor. She was always loving and caring to me that never made me feel away from home. Although many of you may not understand, nor ever want to understand, much of what is written beyond this page, you should at least know that it could not have been done without you. MD.

dc.description.abstract Reversible Data Hiding (RDH) has emerged to be a significant multi-disciplinary research area. Different types of RDH schemes have already been developed and demonstrated their potentials for applications like media-content authentication, copy-right protection, integrity establishment and annotation. Recently, interpolation based RDH (IRDH) schemes have shown great promises for better rate-distortion performance with a set of unique advantages over their counterparts. Despite great promises, existing IRDH schemes, however, have no consideration of ‘effective’ capacity management for varying size of the payload. As a result, disregarding the varying embeddingcapacity requirement, existing IRDH schemes fail to maintain the minimum possible distortion in the embedded image. An IRDH scheme with adaptive embedding is therefore vital for better rate-distortion performance. In this thesis, a new IRDH scheme is developed and presented based on a simplified parabolic interpolation (SPI) and adaptive embedding. Additionally, an adaptive embedding approach is introduced with two new techniques, where a capacity control parameter is formulated and utilized to attain the varying capacity requirement by determining a minimum set of embeddable bits in a pixel for the best possible embedded image quality. The first technique introduces a flag bit for distinguishing the original payload bits from their complement which are embedded in the interpolated pixels. In the second embedding technique, the correlation between an embeddable pixel and estimated versions of an embedded pixel is utilized to avoid the use of any flag bit as such an extra payload bit per pixel can be embedded therein. Thereby, the embedding capacity significantly increases without compromising the image quality for similar values of the capacity control parameter. Computational modeling of the new IRDH scheme is presented and its performance is evaluated with a set of popular test-images. While compared with the prominent IRDH schemes, the proposed scheme both with or without flag demonstrated its efficiency for significantly better embedding rate-distortion performance. Moreover, being up-sampled, the embedded image would have a higher spatial resolution. It also does not require any location map, and thus the total capacity can be effectively used for data embedding. Nevertheless, it keeps the original pixels untouched and thus, would be useful in military and medical image applications that restrict minimum possible changes in the cover images. en_US
