Camera Networks by Matthew Turk,Gang Hua Pdf

As networks of video cameras are installed in many applications like security and surveillance, environmental monitoring, disaster response, and assisted living facilities, among others, image understanding in camera networks is becoming an important area of research and technology development. There are many challenges that need to be addressed in the process. Some of them are listed below: - Traditional computer vision challenges in tracking and recognition, robustness to pose, illumination, occlusion, clutter, recognition of objects, and activities; - Aggregating local information for wide area scene understanding, like obtaining stable, long-term tracks of objects; - Positioning of the cameras and dynamic control of pan-tilt-zoom (PTZ) cameras for optimal sensing; - Distributed processing and scene analysis algorithms; - Resource constraints imposed by different applications like security and surveillance, environmental monitoring, disaster response, assisted living facilities, etc. In this book, we focus on the basic research problems in camera networks, review the current state-of-the-art and present a detailed description of some of the recently developed methodologies. The major underlying theme in all the work presented is to take a network-centric view whereby the overall decisions are made at the network level. This is sometimes achieved by accumulating all the data at a central server, while at other times by exchanging decisions made by individual cameras based on their locally sensed data. Chapter One starts with an overview of the problems in camera networks and the major research directions. Some of the currently available experimental testbeds are also discussed here. One of the fundamental tasks in the analysis of dynamic scenes is to track objects. Since camera networks cover a large area, the systems need to be able to track over such wide areas where there could be both overlapping and non-overlapping fields of view of the cameras, as addressed in Chapter Two: Distributed processing is another challenge in camera networks and recent methods have shown how to do tracking, pose estimation and calibration in a distributed environment. Consensus algorithms that enable these tasks are described in Chapter Three. Chapter Four summarizes a few approaches on object and activity recognition in both distributed and centralized camera network environments. All these methods have focused primarily on the analysis side given that images are being obtained by the cameras. Efficient utilization of such networks often calls for active sensing, whereby the acquisition and analysis phases are closely linked. We discuss this issue in detail in Chapter Five and show how collaborative and opportunistic sensing in a camera network can be achieved. Finally, Chapter Six concludes the book by highlighting the major directions for future research.

The Best Camera Is The One That's With You by Chase Jarvis Pdf

A beacon of creativity with boundless energy, Chase Jarvis is well known as a visionary photographer, director, and social artist. In The Best Camera Is The One That’s With You, Chase reimagines, examines, and redefines the intersection of art and popular culture through images shot with his iPhone. The pictures in the book, all taken with Chase’s iPhone, make up a visual notebook—a photographic journal—from the past year of his life. The book is full of visually-rich iPhone photos and peppered with inspiring anecdotes. Two megapixels at a time, these images have been gathered and bound into a book that represents a stake in the ground. With it, Chase underscores the idea that an image can come from any camera, even a mobile phone. As Chase writes, “Inherently, we all know that an image isn’t measured by its resolution, dynamic range, or anything technical. It’s measured by the simple—sometimes profound, other times absurd or humorous or whimsical—effect that it can have upon us. If you can see it, it can move you.” This book is geared to inspire everyone, regardless of their level of photography knowledge, that you can capture moments and share them with our friends, families, loved ones, or the world at the press of a button. Readers of The Best Camera Is The One That’s With You will also enjoy the iPhone application Chase Jarvis created in conjunction with this book, appropriately named Best Camera. Best Camera has a unique set of filters and effects that can be applied at the touch of a button. Stack them. Mix them. Remix them. Best Camera also allows you to share directly to a host of social marketing sites via www.thebestcamera.com, a new online community that allows you to contribution to a living, breathing gallery of the best iPhone photography from around the globe. Together, the book, app, and website, represent a first-of-its-kind ecosystem dedicated to encouraging creativity through picture taking with the camera that you already have. The Best Camera Is The One That’s With You—shoot!
