 Free Download Variational Methods in Image Segmentation: with seven image processing experiments By Jean Michel Morel, Sergio Solimini (auth.) 1995 | 248 Pages | ISBN: 1468405691 | PDF | 7 MB This book contains both a synthesis and mathematical analysis of a wide set of algorithms and theories whose aim is the automatic segmen tation of digital images as well as the understanding of visual perception. A common formalism for these theories and algorithms is obtained in a variational form. Thank to this formalization, mathematical questions about the soundness of algorithms can be raised and answered. Perception theory has to deal with the complex interaction between regions and "edges" (or boundaries) in an image: in the variational seg mentation energies, "edge" terms compete with "region" terms in a way which is supposed to impose regularity on both regions and boundaries. This fact was an experimental guess in perception phenomenology and computer vision until it was proposed as a mathematical conjecture by Mumford and Shah. The third part of the book presents a unified presentation of the evi dences in favour of the conjecture. It is proved that the competition of one-dimensional and two-dimensional energy terms in a variational for mulation cannot create fractal-like behaviour for the edges. The proof of regularity for the edges of a segmentation constantly involves con cepts from geometric measure theory, which proves to be central in im age processing theory. The second part of the book provides a fast and self-contained presentation of the classical theory of rectifiable sets (the "edges") and unrectifiable sets ("fractals").

Free Download Christian de Pee, "Urban Life and Intellectual Crisis in Middle-Period China, 800-1100 " English | ISBN: 9463721665 | 2022 | 290 pages | PDF | 2 MB In the eleventh century, the cities of the Song Empire (960-1279) emerged into writing. Literati in prior centuries had looked away from crowded streets, but literati in the eleventh century found beauty in towering buildings and busy harbors. Their purpose in writing the city was ideological. On the written page, they tried to establish a distinction that eluded them in the avenues and to discern an immanent pattern in the movement of people, goods, and money. By the end of the eleventh century, however, they recognized that they had failed in their efforts. They had lost the Way in the city. Urban Life and Intellectual Crisis in Middle-Period China, 800-1100 reveals the central place of urban life in the history of the eleventh century. Important developments in literary innovation and monetary policy, in canonical exegesis and civil engineering, in financial reform and public health, converge in this book as they converged in the city.
 Free Download Adèle Esposito, "Urban Development in the Margins of a World Heritage Site: In the Shadows of Angkor " English | ISBN: 9462983682 | 2018 | 340 pages | PDF | 4 MB This volume addresses the relationship between the UNESCO World Heritage Site of Angkor (Cambodia), and the nearby town of Siem Reap. While previous work on heritage sites has mainly focused on protected areas, this book shifts the attention to the margins, where detrimental, tourism-driven urban development may take place. By delimiting a protected site, a non-heritage space is created in which spatial fragmentation, disruptive development processes, and unjust power plays can occur. In post-war Cambodia, liberalization and collective aspirations for progress have provided a strong incentive for modernization. Controversial interests compete in the arena of urban development, and real estate development prevails over planned growth. At the same time, Siem Reap's marginal position allows for some freedom in architectural and urban design. In the shadow of institutional control, this architectural space expresses alternative visions of the Khmer heritage and connects them with images of urban modernity.

Free Download Uninvited Valor: The Forsaken Soldiers of WWII: Based on the Epic True Story of the 442nd Regimental Combat Team by John C. Kiyonaga English | October 17, 2024 | ISBN: 1965253210 | 156 Pages | epub | 1,61 MB  Free Download Uniform Random Numbers: Theory and Practice By Shu Tezuka (auth.) 1995 | 209 Pages | ISBN: 1461359805 | PDF | 6 MB In earlier forewords to the books in this series on Discrete Event Dynamic Systems (DEDS), we have dwelt on the pervasive nature of DEDS in our human-made world. From manufacturing plants to computer/communication networks, from traffic systems to command-and-control, modern civilization cannot function without the smooth operation of such systems. Yet mathemat ical tools for the analysis and synthesis of DEDS are nascent when compared to the well developed machinery of the continuous variable dynamic systems char acterized by differential equations. The performance evaluation tool of choice for DEDS is discrete event simulation both on account of its generality and its explicit incorporation of randomness. As it is well known to students of simulation, the heart of the random event simulation is the uniform random number generator. Not so well known to the practitioners are the philosophical and mathematical bases of generating "random" number sequence from deterministic algorithms. This editor can still recall his own painful introduction to the issues during the early 80's when he attempted to do the first perturbation analysis (PA) experiments on a per sonal computer which, unbeknownst to him, had a random number generator with a period of only 32,768 numbers. It is no exaggeration to say that the development of PA was derailed for some time due to this ignorance of the fundamentals of random number generation. |
