A variety of physical and biomedical imaging techniques, such as digital holography, interferometric synthetic aperture radar InSAR , or magnetic resonance imaging MRI enable measurement of the phase of a physical quantity additionally to its amplitude. Phase unwrapping is the process of obtaining the underlying physical phase map from the wrapped phase. Tile-based phase unwrapping algorithms operate by first tessellating the phase map, then unwrapping individual tiles, and finally merging them to a continuous phase map. They can be implemented computationally efficiently and are robust to noise. However, they are prone to failure in the presence of phase residues or erroneous unwraps of single tiles. We tried to overcome these shortcomings by creating novel tile unwrapping and merging algorithms as well as creating a framework that allows to combine them in modular fashion. To increase the robustness of the tile unwrapping step, we implemented a model-based algorithm that makes efficient use of linear algebra to unwrap individual tiles.


This NP-hard problem is of considerable practical interest, largely due to its importance in interpreting data acquired with synthetic aperture radar SAR interferometry. Consequently, many heuristic algorithms have been proposed. We present an efficient multi-level graph algorithm for the approximate solution of an equivalent problem—minimal residue cut in the dual graph.

A resource like no other-the first comprehensive guide to phase unwrapping Phase unwrapping is a mathematical problem-solving technique increasingly used in synthetic aperture radar SAR interferometry, optical interferometry, adaptive optics, and medical imaging. In Two-Dimensional Phase Unwrapping, two internationally recognized experts sort through the multitude of ideas and algorithms cluttering current research, explain clearly how to solve phase unwrapping problems, and provide practicable algorithms that can be applied to problems encountered in diverse disciplines. Complete with case studies and examples as well as hundreds of images and figures illustrating the concepts, this book features: A thorough introduction to the theory of phase unwrapping Eight algorithms that constitute the state of the art in phase unwrapping Detailed description and analysis of each algorithm and its performance in a number of phase unwrapping problems C language software that provides a complete implementation of each algorithm Comparative analysis of the algorithms and techniques for evaluating results A discussion of future trends in phase unwrapping research Foreword by former NASA scientist Dr. John C. Curlander Two-Dimensional Phase Unwrapping skillfully integrates concepts, algorithms, software, and examples into a powerful benchmark against which new ideas and algorithms for phase unwrapping can be tested.

Прозвучал еще один выстрел. Он принял решение. Под визг покрышек, в снопе искр Беккер резко свернул вправо и съехал с дороги.

 - Беккер понял, что совершил какой-то промах. - Да, наше агентство предоставляет сопровождающих бизнесменам для обедов и ужинов. Вот почему мы внесены в телефонный справочник.

Повинуясь инстинкту, он резко нажал на тормоза, но мотоцикл не остановился на скользком от машинного масла полу. Веспу понесло. Рядом раздался оглушающий визг тормозов такси, его лысая резина заскользила по полу. Машина завертелась в облаке выхлопных газов совсем рядом с мотоциклом Беккера. Теперь обе машины, потеряв управление, неслись к стене ангара. Беккер отчаянно давил на тормоз, но покрышки потеряли всякое сцепление с полом.

 Тебе больше нечем заняться? - Сьюзан метнула на него недовольный взгляд. - Хочешь от меня избавиться? - надулся Хейл. - Если честно - да, - Не надо так, Сью, Ты меня оскорбляешь. Глаза Сьюзан сузились. Она терпеть не могла, когда он называл ее Сью. Вообще-то она ничего не имела против этого имени, но Хейл был единственным, кто его использовал, и это было ей неприятно.

We apologize for the inconvenience...

Дэвид, - сказал наконец Стратмор мрачным голосом, - обнаружение этого кольца - вопрос национальной безопасности. Я возлагаю эту задачу на. Не подведите .
