Real-Time Progressive Hyperspectral Image Processing
Imaging spectroscopy, also known as hyperspectral imaging, has been transformed in less than 30 years from being a sparse research tool into a commodity product available to a broad user community. Currently, there is a need for standardized data processing techniques able to take into account the special properties of hyperspectral data. In this paper, we provide a seminal view on recent advances in techniques for hyperspectral image processing. Our main focus is on the design of techniques able to deal with the highdimensional nature of the data, and to integrate the spatial and spectral information. Performance of the discussed techniques is evaluated in different analysis scenarios. Combined, these parts provide an excellent snapshot of the state-of-the-art in those areas, and offer a thoughtful perspective on future potentials and emerging challenges in the design of robust hyperspectral imaging algorithms.

Use of this web site signifies your agreement to the terms and conditions. Despite the growing interest in hyperspectral imaging research, only a few efforts devoted to designing and implementing well-conformed parallel processing solutions currently exist in the open literature. With the recent explosion in the amount and dimensionality of hyperspectral imagery, parallel processing is expected to become a requirement in most remote sensing missions. In this paper, we take a necessary first step towards the quantitative comparison of parallel techniques and strategies for analyzing hyperspectral data sets. Our focus is on three types of algorithms: automatic target recognition, spectral mixture analysis and data compression.
It seems that you're in Germany. We have a dedicated site for Germany. The book covers the most crucial parts of real-time hyperspectral image processing: causality and real-time capability. Both of these can be used to design algorithms and also form an integral part of real time hyperpsectral image processing. This book focuses on progressive nature in algorithms on their real-time and causal processing implementation in two major applications, endmember finding and anomaly detection, both of which are fundamental tasks in hyperspectral imaging but generally not encountered in multispectral imaging. This book is written to particularly address PHSI in real time processing, while a book, Recursive Hyperspectral Sample and Band Processing: Algorithm Architecture and Implementation Springer can be considered as its companion book. Chang has published over referred journal articles, including more than 50 papers in the IEEE Transaction on Geoscience and Remote Sensing alone and four patents with several pending on hyperspectral image processing.

The use of hyperspectral cameras is well established in the field of plant phenotyping, especially as a part of high-throughput routines in greenhouses. Nevertheless, the workflows used differ depending on the applied camera, the plants being imaged, the experience of the users, and the measurement set-up. This review describes a general workflow for the assessment and processing of hyperspectral plant data at greenhouse and laboratory scale. Aiming at a detailed description of possible error sources, a comprehensive literature review of possibilities to overcome these errors and influences is provided. The processing of hyperspectral data of plants starting from the hardware sensor calibration, the software processing steps to overcome sensor inaccuracies, and the preparation for machine learning is shown and described in detail. Furthermore, plant traits extracted from spectral hypercubes are categorized to standardize the terms used when describing hyperspectral traits in plant phenotyping. A scientific data perspective is introduced covering information for canopy, single organs, plant development, and also combined traits coming from spectral and 3D measuring devices.
Basic Hyperspectral Analysis Tutorial This tutorial introduces you to visualization and interactive analysis tools for working with hyperspectral data. In this tutorial, you will:. Use this tutorial with ENVI 5. The names of some menu items and the appearance of plot windows will vary, depending on the version you use. You will also use some mineral spectral library files that are included with your ENVI installation.

Hyperspectral imaging , like other spectral imaging , collects and processes information from across the electromagnetic spectrum. There are push broom scanners and the related whisk broom scanners spatial scanning , which read images over time, band sequential scanners spectral scanning , which acquire images of an area at different wavelengths, and snapshot hyperspectral imaging , which uses a staring array to generate an image in an instant. Whereas the human eye sees color of visible light in mostly three bands long wavelengths - perceived as red, medium wavelengths - perceived as green, and short wavelengths - perceived as blue , spectral imaging divides the spectrum into many more bands. This technique of dividing images into bands can be extended beyond the visible. In hyperspectral imaging, the recorded spectra have fine wavelength resolution and cover a wide range of wavelengths.
Hyperspectral data processing; algorithm design and analysis. Chang, Chein-I. Specifically, it treats hyperspectral image processing and hyperspectral signal processing as separate subjects in two Recent advances in the sensors technology for imaging spectroscopy coupled with high computing power, raise the demand to develop the algorithms for processing and analysis of hyperspectral data for various applications.
В сознании Сьюзан промелькнуло все то, что она читала о приемах самозащиты. Она попыталась бороться, но тело ее не слушалось. Она точно окаменела. И закрыла. О Боже, пожалуйста.
Кто бы мог подумать. - Проваливай! - крикнула. - Вон. Беккер совсем забыл о кольце, об Агентстве национальной безопасности, обо всем остальном, проникшись жалостью к девушке. Наверное, родители отправили ее сюда по какой-то школьной образовательной программе, снабдив кредитной карточкой Виза, а все кончилось тем, что она посреди ночи вкалывает себе в туалете наркотик.
