The book provides insights into International Conference on Intelligent Systems and Signal Processing (ISSP 2017) held at G.H. Patel College of Engineering & Technology, Gujarat, India during March 24-25, 2017. The book comprises contributions by the research scholars and academicians covering the topics in signal processing and communication engineering, applied electronics and emerging technologies, computer vision and machine learning, big data and cloud computing and advanced intelligent power electronics and drives systems. The main emphasis of the book is on dissemination of information, experience and research results on the current topics of interest through in-depth discussions and contribution of researchers from all over world. The book is useful for research community, academicians, industrialists and post graduate students across the globe.

Digital Watermarking is the process of inserting a digital signal of a defined pattern into digital data. This is used to identify the owner of the work, to authenticated the content, to trace illegal copies of the work and other similar purposes. While the technology for information transmission has changed much with the advent of the digital age, the concerns related to protection and enforcement in intellectual property rights of the digital contents involved in the transaction has been raised. This has made digital watermarking one of the hottest research topics in recent times. In this book, we provides a comparative study of different digital watermarking techniques in spatial and transform domain. Number of watermarking techniques in each domain has been verified and are compared based on their performance against different noise factors and block size. The implementation of techniques has been demonstrated using an interactive graphical user interface (GUI).
