The ultimate guide to predicting winners and losers in high technology Pip Coburn became famous for writing some of the liveliest reports on Wall Street. He quoted everyone from Machiavelli to HAL, Anaïs Nin to Yoda, Einstein to Gandhi. But along with the quirky writing, he consistently delivered sharp insights into technology trends and helped investors pick stocks with long-term potential. After years of studying countless winners and losers, Coburn has come up with a simple idea that explains why some technologies become huge hits (iPods, DVD players, Netflix), but others never reach more than a tiny audience (Segways, video phones, tablet PCs). He says that people are only willing to change when the pain of their current situation outweighs the perceived pain of trying something new. In other words, technology demands a change in habits, and that’s the leading cause of failure for countless cool inventions. Too many tech companies believe in "build it and they will come"— build something better and people will beat a path to your door. But, as Coburn shows, most potential users are afraid of new technologies, and they need a really great reason to change. The Change Function is an irreverent look at how this pattern plays out in countless sectors, from computers to cell phones to digital TV recorders. It will be an invaluable book for people who create and invest in new technologies.

ICIAR 2004, the International Conference on Image Analysis and Recognition, was the ?rst ICIAR conference, and was held in Porto, Portugal. ICIAR will be organized annually, and will alternate between Europe and North America. ICIAR 2005 will take place in Toronto, Ontario, Canada. The idea of o?ering these conferences came as a result of discussion between researchers in Portugal and Canada to encourage collaboration and exchange, mainly between these two countries, but also with the open participation of other countries, addressing recent advances in theory, methodology and applications. The response to the call for papers for ICIAR 2004 was very positive. From 316 full papers submitted, 210 were accepted (97 oral presentations, and 113 - sters). The review process was carried out by the Program Committee members and other reviewers; all are experts in various image analysis and recognition areas. Each paper was reviewed by at least two reviewing parties. The high q- lity of the papers in these proceedings is attributed ?rst to the authors, and second to the quality of the reviews provided by the experts. We would like to thank the authors for responding to our call, and we wholeheartedly thank the reviewers for their excellent work in such a short amount of time. We are espe- ally indebted to the Program Committee for their e?orts that allowed us to set up this publication. We were very pleased to be able to include in the conference, Prof. Murat KuntfromtheSwissFederalInstituteofTechnology,andProf. Mario ́ Figueiredo, oftheInstitutoSuperiorT ́ ecnico,inPortugal.

Creating an idealized image of a subject is a portrait photographer's job. However, the approach is not quite formulaic. From one subject to the next and one day to the next, there are different goals and scenarios—on Monday, you may be tasked with photographing your subjects under cloudy skies on a beach; on Tuesday, you may need want to downplay your client's wide hips in the studio; on Wednesday, you may want to create dramatic lighting for an actor's portfolio—on-stage. Every day, there is a unique challenge to meet, often under varying conditions. So, how do you make a magically good portrait during every shoot? In this book, Bill Israelson shows you how to tackle the problem of creating a great portrait of your every client. Beginning with a discussion on equipment essentials, breaking the discussion into two topics—gear for studio work and portable equipment for location work. Next, you'll learn simple posing strategies for making women, men, kids, and groups looks their best in any presentation. You'll learn how to position the body from head to toe to maximize assets and downplay common problem areas. Lighting is the backbone of every image. In the studio, you have complete control over every facet of the lighting—from its hardness or softness to its color temperature and direction. On location, the basic principles of good lighting still apply—but the quality and quantity of light is subject to change. Israelson shows you how to harness the available light and supplement it when needed to create saleable images every time. With straightforward, jargon-free text and a wide range of image examples, this book will help you quickly learn how to improve your portrait results to create client-pleasing portraits every time.

DOWNLOAD NOW »
A human observer is able to recognize the color of objects irrespective of the light used to illuminate them. This is called color constancy. A digital camera uses a sensor to measure the reflected light, meaning that the measured color at each pixel varies according to the color of the illuminant. Therefore, the resulting colors may not be the same as the colors that were perceived by the observer. Obtaining color constant descriptors from image pixels is not only important for digital photography, but also valuable for computer vision, color-based automatic object recognition, and color image processing in general. This book provides a comprehensive introduction to the field of color constancy, describing all the major color constancy algorithms, as well as presenting cutting edge research in the area of color image processing. Beginning with an in-depth look at the human visual system, Ebner goes on to: examine the theory of color image formation, color reproduction and different color spaces; discuss algorithms for color constancy under both uniform and non-uniform illuminants; describe methods for shadow removal and shadow attenuation in digital images; evaluate the various algorithms for object recognition and color constancy and compare this to data obtained from experimental psychology; set out the different algorithms as pseudo code in an appendix at the end of the book. Color Constancy is an ideal reference for practising engineers, computer scientists and researchers working in the area of digital color image processing. It may also be useful for biologists or scientists in general who are interested in computational theories of the visual brain and bio-inspired engineering systems.
