A native of Ankara, the young Cihat is looking for vacation lessons to improve his French and thereby the bad grades he makes at the Lycée. The perfection of the documentation received from the University of Lausanne will profoundly change the course of its existence. During his lessons, he meets young students from the École Polytechnique. With his baccalaureate in his pocket, he left his native country to do his studies and his doctorate in Lausanne. He then left to conquer the United States and worked at MIT. He can no longer renew his passport and can no longer reside in Boston. He returned to Switzerland to be naturalized and was appointed professor in the school where he studied. He travels around the world, he crosses the continents from Antarctica to Siberia, from Japan to Latin America, he travels the Silk Road and visits more than a third of the existing countries. All he remembers about himself, believing to be the good sides of each civilization and society, isolate him from those around him. Having become a citizen of the world, all alone, he wonders where he comes from and where he is going.

In recent years there has been an increasing interest in Second Generation Image and Video Coding Techniques. These techniques introduce new concepts from image analysis that greatly improve the performance of the coding schemes for very high compression. This interest has been further emphasized by the future MPEG 4 standard. Second generation image and video coding techniques are the ensemble of approaches proposing new and more efficient image representations than the conventional canonical form. As a consequence, the human visual system becomes a fundamental part of the encoding/decoding chain. More insight to distinguish between first and second generation can be gained if it is noticed that image and video coding is basically carried out in two steps. First, image data are converted into a sequence of messages and, second, code words are assigned to the messages. Methods of the first generation put the emphasis on the second step, whereas methods of the second generation put it on the first step and use available results for the second step. As a result of including the human visual system, second generation can be also seen as an approach of seeing the image composed by different entities called objects. This implies that the image or sequence of images have first to be analyzed and/or segmented in order to find the entities. It is in this context that we have selected in this book three main approaches as second generation video coding techniques: Segmentation-based schemes Model Based Schemes Fractal Based Schemes GBP/LISTGBP Video Coding: The Second Generation Approach is an important introduction to the new coding techniques for video. As such, all researchers, students and practitioners working in image processing will find this book of interest.
