Crop monitoring for nutrients, water-stress, disease, insect attack and overall plant health is a vital aspect of successful agricultural operations. Traditionally this has been carried out by visual examination of crops on the ground or sometimes from the air. However these methods are limited by the ability of the human eye to discriminate between healthy foliage and foliage suffering various kinds of stress. Often a specific condition must be well-advanced before visual symptoms become noticeable even to experienced observers. Modern precision agriculture relies on site-specific management tactics to maximize yield and resources while reducing environmental impacts such as over-fertilization and the broad applications of pesticides. Pin-pointing areas requiring attention — be it water, weed or pathogen treatment, or nutrient adjustments — allows for spot application rather than whole-field treatment. The collection of key data at a sufficient level of accuracy depends on the availability of equipment that can be operated at a cost-effective level.

Hyperspectral imaging, as an emerging technology, acquires and analyzes a large amount of spectral and spatial information from a real scene in the form of three-dimensional images. The technology offers unprecedented capabilities, compared to conventional imaging and spectroscopy, for a wide range of applications from satellite remote sensing to biomedical imaging and to product quality and safety inspection. Image processing and analysis is thus at the core of the technology. Hyperspectral Imaging Technology in Food and Agriculture is focused on major recent advances in research and applications of hyperspectral imaging technology in food and agriculture. The book begins with the fundamentals of the technology, followed by a comprehensive coverage of food quality and safety evaluation in meats, fruits, vegetables, grains and other foods, as well as remote sensing for crop production. This book is written by international peers who have academic and professional credentials, with each chapter addressing a particular topic or specific application of the technology. The book provides the engineer and technologist working in the food and agricultural industry with critical, comprehensive and readily accessible information on hyperspectral imaging technology.

Based on the integration of computer vision and spectrscopy techniques, hyperspectral imaging is a novel technology for obtaining both spatial and spectral information on a product. Used for nearly 20 years in the aerospace and military industries, more recently hyperspectral imaging has emerged and matured into one of the most powerful and rapidly growing methods of non-destructive food quality analysis and control. Hyperspectral Imaging for Food Quality Analysis and Control provides the core information about how this proven science can be practically applied for food quality assessment, including information on the equipment available and selection of the most appropriate of those instruments. Additionally, real-world food-industry-based examples are included, giving the reader important insights into the actual application of the science in evaluating food products. Food engineers and technologists working in research, product and process development, and operations. Undergraduate and graduate food science students exploring food quality and control. Da-Wen Sun is internationally recognized for his leadership in food engineering research and education and is a highly respected journal editor.

chapter and author info

Over the past decade, hyperspectral imaging has been rapidly developing and widely used as an emerging scientific tool in nondestructive fruit and vegetable quality assessment. Hyperspectral imaging technique integrates both the imaging and spectroscopic techniques into one system, and it can acquire a set of monochromatic images at almost continuous hundreds of thousands of wavelengths. This chapter presents a detailed overview of the introduction, latest developments and applications of hyperspectral imaging in the nondestructive assessment of fruits and vegetables. Additionally, the principal components, basic theories, and corresponding processing and analytical methods are also reported in this chapter. Hyperspectral Imaging in Agriculture, Food and Environment. In recent years, consumer demand for fruits and vegetables tends to be diversified, and more attention has been paid to the external quality of apples. Consequently, the accurate, rapid, and objective assessment system in the processing stage is essential to ensure the quality of fruits and vegetables during processing operations.

It seems that you're in Germany. We have a dedicated site for Germany. Hyperspectral imaging or imaging spectroscopy is a novel technology for acquiring and analysing an image of a real scene by computers and other devices in order to obtain quantitative information for quality evaluation and process control. Image processing and analysis is the core technique in computer vision. With the continuous development in hardware and software for image processing and analysis, the application of hyperspectral imaging has been extended to the safety and quality evaluation of meat and produce. Especially in recent years, hyperspectral imaging has attracted much research and development attention, as a result rapid scientific and technological advances have increasingly taken place in food and agriculture, especially on safety and quality inspection, classification and evaluation of a wide range of food products, illustrating the great advantages of using the technology for objective, rapid, non-destructive and automated safety inspection as well as quality control.

 Сколько там этих сироток? - спросила. Соши развела руками. Она села за терминал Джаббы и перепечатала все группы, а закончив, подбежала к Сьюзан. Все посмотрели на экран.

Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ. Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты. Каждую весну, когда частные фирмы начинают охоту за талантливой молодежью, соблазняя ее неприлично высокими окладами и фондовыми опционами в придачу, АНБ внимательно наблюдает за этим, выделяет наиболее подходящих и удваивает предлагаемую сумму.

Коммандер. Северная Дакота - это Хейл. Но Стратмор смотрел на молодого сотрудника лаборатории систем безопасности. Коммандер спускался по лестнице, ни на мгновение не сводя с него глаз. Он быстро подошел к ним и остановился в нескольких сантиметрах от дрожащего Чатрукьяна.

Повисло молчание. Казалось, эта туша собирается что-то сказать, но не может подобрать слов. Его нижняя губа на мгновение оттопырилась, но заговорил он не. Слова, сорвавшиеся с его языка, были определенно произнесены на английском, но настолько искажены сильным немецким акцентом, что их смысл не сразу дошел до Беккера.

Что привело вас в Севилью. - Я торговец ювелирными изделиями. Жемчугами из Майорки.

 Какого чер… В распечатке был список последних тридцати шести файлов, введенных в ТРАНСТЕКСТ. За названием каждого файла следовали четыре цифры - код команды добро, данной программой Сквозь строй. Последний файл в списке таким кодом не сопровождался, вместо этого следовала запись: ФИЛЬТР ОТКЛЮЧЕН ВРУЧНУЮ. Господи Иисусе! - подумал Бринкерхофф.

Ничего более абсурдного Сьюзан слышать еще не доводилось. Цифровая крепость - не поддающийся взлому код, он погубит агентство. - Если бы я сумел слегка модифицировать этот код, - продолжал Стратмор, - до его выхода в свет… - Он посмотрел на нее с хитрой улыбкой. Сьюзан потребовалось всего мгновение.

Правой рукой, точно железной клешней, он обхватил ее за талию так сильно, что она вскрикнула от боли, а левой сдавил ей грудную клетку. Сьюзан едва дышала. Отчаянно вырываясь из его рук, Сьюзан локтем с силой ударила Хейла. Он отпустил ее и прижал ладони к лицу. Из носа у него пошла кровь.

Коммандер шел в Третий узел - к Сьюзан. К своему будущему. Шифровалка снова купалась в ярких огнях.
