Book Description
Communications represent a strategic sector for privacy protection and for personal, company, national and international security. The interception, damage or lost of information during communication can generate material and non material economic damages from both a personal and collective point of view. The purpose of this book is to give the reader information relating to all aspects of communications security, beginning at the base ideas and building to reach the most advanced and updated concepts. The book will be of interest to integrated system designers, telecommunication designers, system engineers, system analysts, security managers, technicians, intelligence personnel, security personnel, police, army, private investigators, scientists, graduate and postgraduate students and anyone that needs to communicate in a secure way.

Book Description
Digital watermarking is a method in which the information is embedded directly and imperceptibly into digital data. Potential applications of digital watermarking include copyright protection and authentication. In this monograph a set of novel and generic watermarking scheme has been developed for colored digital images that can embed a holographic logo or a meaningful text. The general watermarking mechanism has been discussed in chapter 1, and a review of algorithms in chapter 2. The colored image watermarking using DCT transformation has been coined in chapter 3. The technique acts as a model for watermarking colored images. The model is advanced and an edge sensitive algorithm is discussed in chapter 4. This algorithm embeds watermark only in sensitive areas of the image thus securing the actual concerned content of the image. The algorithm has been sophisticated further with the incorporation of chaotic system in chapter 5. The algorithm used chaotic dynamical system for determining the strength factor for incorporation of watermark thereby addressing Kerckhoffs' principle. Finally, chapter 6 provides the nutshell of the work.

Computing Colour Image Processing

Book Description
This book proposes a new approach to colour in digital images, based on the standard sRGB colour space and Python scripting. It covers creating, storing, processing, displaying, printing, and viewing colour images. The fundamental ideas presented include systematic reduction of colour resolution to manageable sRGB sub-spaces, analysis of any image as a tabular colour scheme, general transformation and specific substitution of colours, and revival of the traditional notion of a neutral balance by adjusting all colours or by adjoining a colour frame. The text includes Python scripts for the processes discussed, downloadable in the e-book. It is of interest to artists, designers, and anyone who works with sRGB colour images.

Book Description
Learn to harness and capture infrared wavelengths with an infrared-converted digital camera. The authors teach you how those invisible light wavelengths will be recorded in-camera and the steps you’ll need to take to ensure the best-possible photographs. You’ll study myriad images that show how various materials—from skin, hair, and eyes to the sky, trees, grasses, and clouds—will appear in your images and learn to predict the way that the colors and tones you perceive with your naked eyes will be rendered in-camera. You will discover compositional techniques that will visually engage your audience. Finally, you’ll learn how to use artistic applications to add selective color to your black & white infrared images, how to create dramatic color infrared photographs that take infrared capture to a whole new level, and how to edit your images in postproduction for enhanced contrast and superb detail.

Book Description
Well-documented scenes can prove to be invaluable pieces of evidence at trial, and the ability to take compelling photographs is a critical skill for forensic scientists and investigators. Practical Forensic Digital Imaging: Applications and Techniques is an up-to-date and thorough treatment of digital imaging in the forensic sciences. Balancing practical considerations with scientific and standards-based requirements, the book’s clear, concise presentation illustrates the essentials of digital imaging required by professionals in the field. Enhanced with crisp color photos, the book covers a host of critical topics, including: The fundamentals of photographing crime scenes The history of photography and the transition to digital imaging Digital camera hardware and photographic techniques Light, filters, and macro/micro imaging Lay, professional, and expert witnesses, and the implications of Frye and Daubert Enhancement of images and digital panoramic camera scanning Storage of digital media Ultraviolet and infrared imaging Digital photo imaging microscopes Covering the full range of scenarios that forensic professionals encounter, the author includes special sections dedicated to photography involving footwear and tire impressions, vehicles, death and morgue scenes, and taphonomic and entomological imaging, as well as fingerprints, burglaries, fire and arson, sex offenses, blood, and trace evidence and microscopy. The techniques in this volume enable photographers to capture the images that will not only tell the story, but will also stand up in court.

Book Description
Digital sculpting is the use of tools to push, pull, smooth, grab, pinch or otherwise manipulate a digital object as if it were made of a real-life substance such as clay. Mudbox is the premier sculpting solution for digital artists, in that it allows them to naturally and easily sculpt detailed, organic characters and models in a way that feels like traditional sculpting. This book guides CG professionals through the process of creating amazing digital sculptures using the Mudbox arsenal of ground-breaking digital sculpting and 3D painting tools, and porting the models into their Maya or Max work. Artists will explore tried and true, traditional, sculpting techniques and learn to apply them to digital sculpting. A series of in-depth tutorials are incluced, each challenging them with progressively more complex models as they go on. Unique to this book are topics specific to fine art sculptors transitioning from traditional sculpting to digital sculpting. information found nowhere else for professional sculptors shows them how to successfully integrate digital sculpting into their workflow. Associated web site with: support files, models, materials, and textures for completing the tutorials in the book.

Book Description
The first edition of the Encyclopedia of Optical and Photonic Engineering provided a valuable reference concerning devices or systems that generate, transmit, measure, or detect light, and to a lesser degree, the basic interaction of light and matter. This Second Edition not only reflects the changes in optical and photonic engineering that have occurred since the first edition was published, but also: Boasts a wealth of new material, expanding the encyclopedia’s length by 25 percent Contains extensive updates, with significant revisions made throughout the text Features contributions from engineers and scientists leading the fields of optics and photonics today With the addition of a second editor, the Encyclopedia of Optical and Photonic Engineering, Second Edition offers a balanced and up-to-date look at the fundamentals of a diverse portfolio of technologies and discoveries in areas ranging from x-ray optics to photon entanglement and beyond. This edition’s release corresponds nicely with the United Nations General Assembly’s declaration of 2015 as the International Year of Light, working in tandem to raise awareness about light’s important role in the modern world.
