Book Description
Digital cameras, both in traditional form factors and as parts of cell phones, have become ubiquitous over the last decade. But for the most part, they remain black boxes to the end-user, and cannot be reprogrammed or modified. This has become an obstacle to researchers in the new field of computational photography, who want to use the growing computing power of digital cameras to create images no traditional camera could produce. This dissertation presents the Frankencamera platform, a digital camera system designed for computational photography. The Frankencamera is a fully open, fully programmable digital camera, which can be easily modified to test out new research ideas. The Frankencamera architecture allows for per-frame control of the capture process, and accurate synchronization of all the components that make up the camera. Based on this architecture, this dissertation details two hardware platforms: the F2, a flexible custom-built camera; and the Nokia N900, a commercial smartphone. Both platforms can be easily programmed at a high level using the FCam API, written to embody the Frankencamera architecture. Finally, this dissertation presents several sample applications for the Frankencamera platform. Several of these applications could not have been developed for any existing camera platform, and the ease and speed at which they were written show that the Frankencamera platform is a compelling tool for computational photography.

Book Description
Most emerging applications in imaging and machine learning must perform immense amounts of computation while holding to strict limits on energy and power. To meet these goals, architects are building increasingly specialized compute engines tailored for these specific tasks. The resulting computer systems are heterogeneous, containing multiple processing cores with wildly different execution models. Unfortunately, the cost of producing this specialized hardware—and the software to control it—is astronomical. Moreover, the task of porting algorithms to these heterogeneous machines typically requires that the algorithm be partitioned across the machine and rewritten for each specific architecture, which is time consuming and prone to error. Over the last several years, the authors have approached this problem using domain-specific languages (DSLs): high-level programming languages customized for specific domains, such as database manipulation, machine learning, or image processing. By giving up generality, these languages are able to provide high-level abstractions to the developer while producing high-performance output. The purpose of this book is to spur the adoption and the creation of domain-specific languages, especially for the task of creating hardware designs. In the first chapter, a short historical journey explains the forces driving computer architecture today. Chapter 2 describes the various methods for producing designs for accelerators, outlining the push for more abstraction and the tools that enable designers to work at a higher conceptual level. From there, Chapter 3 provides a brief introduction to image processing algorithms and hardware design patterns for implementing them. Chapters 4 and 5 describe and compare Darkroom and Halide, two domain-specific languages created for image processing that produce high-performance designs for both FPGAs and CPUs from the same source code, enabling rapid design cycles and quick porting of algorithms. The final section describes how the DSL approach also simplifies the problem of interfacing between application code and the accelerator by generating the driver stack in addition to the accelerator configuration. This book should serve as a useful introduction to domain-specialized computing for computer architecture students and as a primer on domain-specific languages and image processing hardware for those with more experience in the field.

Book Description
From Snapshots to Social Media describes the history and future of domestic photography as mediated by technological change. Domestic photography refers to the culture of ordinary people capturing, sharing and using photographs, and is in a particular state of flux today as photos go digital. The book argues that this digital era is the third major chapter in the 170 year history of the area; following the portrait and Kodak eras of the past. History shows that despite huge changes in photographic technology and the way it has been sold, people continue to use photographs to improve memory, support communication and reinforce identity. The future will involve a shift in the balance of these core activities and a replacement of the family album with various multimedia archives for individuals, families and communities. This raises a number of issues that should be taken into account when designing new technologies and business services in this area, including: the ownership and privacy of content, multimedia standards, home ICT infrastructure, and younger and older users of images. The book is a must for designers and engineers of imaging technology and social media who want a better understanding of the history of domestic photography in order to shape its future. It will also be of value to students and researchers in science and technology studies and visual culture, as a fascinating case study of the evolving use of photographs and photographic technology in Western society.
