Biological systems are a source of inspiration in the development of small autonomous sensor nodes. The two major types of optical vision systems found in nature are the single aperture human eye and the compound eye of insects. The latter are among the most compact and smallest vision sensors. The eye is a compound of individual lenses with their own photoreceptor arrays. The visual system of insects allows them to fly with a limited intelligence and brain processing power. A CMOS image sensor replicating the perception of vision in insects is discussed and designed in this book for industrial (machine vision) and medical applications.
The CMOS metal layer is used to create an embedded micro-polarizer able to sense polarization information. This polarization information is shown to be useful in applications like real time material classification and autonomous agent navigation. Further the sensor is equipped with in pixel analog and digital memories which allow variation of the dynamic range and in-pixel binarization in real time. The binary output of the pixel tries to replicate the flickering effect of the insect's eye to detect smallest possible motion based on the change in state. An inbuilt counter counts the changes in states for each row to estimate the direction of the motion. The chip consists of an array of 128x128 pixels, it occupies an area of 5 x 4 mm2 and it has been designed and fabricated in an 180nm CMOS CIS process from UMC.
Rick Sammon's Evolution of an Image illustrates the creative photographic process from start to finish. In this book, Canon Explorer of Light Rick Sammon pulls back the curtain to prove that creating amazing photographs is a well-thought-out process that involves several stages.
Comprising 50 case studies that examine photographs taken by Rick around the world in a wide variety of shooting situations, Evolution of an Image shows the power of creative thinking, getting it right in the camera, and the careful use of image processing using Lightroom.
By including his outtakes- and the reasons that he considers them outtakes- Rick suggests the steps that every photographer should take in order to improve their images. Combining technical advice with tips on lighting, composition and using Lightroom, this book will motivate and encourage those looking to evolve as creative photographers and digital darkroom artists.
Key features include:
More than 200 before-and-after photographs
Fully illustrated sections on wildlife, seascape, landscape, scenic, action and people photography
Screen grabs showing Rick's Lightroom adjustments
Suggestions on working in Adobe Photoshop Lightroom as well as Adobe Photoshop
Special section on Rick's "Sammonisms," or quick tips on getting the best in-camera image
Advice on evolving as a photographer
Inspirational photographs from Provence, the Palouse, Kenya, Antarctica, Iceland, Alaska, Mongolia, Myanmar, Colorado and more
Remote Sensing Digital Image Analysis provides the non-specialist with an introduction to quantitative evaluation of satellite and aircraft derived remotely retrieved data. Since the first edition of the book there have been significant developments in the algorithms used for the processing and analysis of remote sensing imagery; nevertheless many of the fundamentals have substantially remained the same. This new edition presents material that has retained value since those early days, along with new techniques that can be incorporated into an operational framework for the analysis of remote sensing data.
Each chapter covers the pros and cons of digital remotely sensed data, without detailed mathematical treatment of computer based algorithms, but in a manner conductive to an understanding of their capabilities and limitations. Problems conclude each chapter.
Digital phase lock loops are critical components of many communication, signal processing and control systems. This exciting new book covers various types of digital phase lock loops. It presents a comprehensive coverage of a new class of digital phase lock loops called the time delay tanlock loop (TDTL). It also details a number of architectures that improve the performance of the TDTL through adaptive techniques that overcome the conflicting requirements of the locking rage and speed of acquisition. These requirements are of paramount importance in many applications including wireless communications, consumer electronics and others. Digital Phase Lock Loops then illustrates the process of converting the TDTL class of digital phase lock loops for implementation on an FPGA-based reconfigurable system. These devices are being utilized in software-defined radio, DSP-based designs and many other communication and electronic systems to implement complex high-speed algorithms. Their flexibility and reconfigurability facilitate rapid prototyping, on-the-fly upgradeability, and code reuse with minimum effort and complexity. The practical real-time results, of the various TDTL architectures, obtained from the reconfigurable implementations are compared with those obtained through simulations with MATLAB/Simulink. The material in this book will be valuable to researchers, graduate students, and practicing engineers.
Although the Israeli state subscribes to the principles of administrative fairness and equality for Jews and Arabs before the law, the reality looks very different. Focusing on Arab land loss inside Israel proper and the struggle over development resources, this study explores the interaction between Arab local authorities, their Jewish neighbors, and the agencies of the national government in regard to developing local and regional industrial areas. The author avoids reduction to simple models of binary domination, revealing instead a complex, multi-dimensional field of relations and ever-shifting lines of political maneuver and confrontation. He examines the prevailing concept of ethnic traditionalism and argues that the image of Arab traditionalism erects imaginary boundaries around the Arab localities, making government incursion disappear from view, while underpinning and rationalizing the exclusion of the Arab towns from development planning. Moreover, he shows how images of environmental protection mesh with and support such exclusion. The study includes a chronology of events, tables, maps, and photographs.
This revised paperback edition with a new epilogue brings accounts of Arab land loss and struggles for economic development up to date. The author also deals with the challenges of life and research in Israel and examines the possibilities of sharing the land as the homeland of both Jews and Palestinians.
