Available in PDF, EPUB and Kindle. Book excerpt: Image sequence processing is becoming a tremendous tool to analyze spatio-temporal data in all areas of natural science. It is the key to studythe dynamics of of complex scientific phenomena. Methods from computer science and the field of application are merged establishing new interdisciplinary research areas. This monograph emerged from scientific applications and thus is an example for such an interdisciplinaryapproach. It is addressed both to computer scientists and to researchers from other fields who are applying methods of computer vision. The results presented are mostly from environmental physics (oceanography) but they will be illuminating and helpful for researchers applying similar methods in other areas.
Download or read book Spatio temporal Filtering for Images and Videos written by Dung Trung Vo and published by . This book was released on 2009 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital images and videos are compressed by removing their spatial, temporal and visual redundancies. Although the encoded signals are more compact and easier for storing or transmitting, the correlation between their pixels is distorted. This causes coding artifacts, which degrade the visual quality of the signals and cause annoyance to the viewers. Compressed images and video sequences should be enhanced prior to being sent to the displaying devices. Previous methods on quality enhancement focused on separately improving the quality of each frames. In this way, the temporal consistency between frames is not guaranteed. Furthermore, characteristics of temporal artifacts are not thoroughly studied and exploited for artifact removal. This dissertation investigates these characteristics and proposes novel methods to reduce both spatial and temporal artifacts. The dissertation covers three main topics in spatio-temporal filtering: quality enhancement, coding and data pruning. The dissertation starts with analyzing the usage of further information from surrounding frames beside the information in the current frames. First, a simple linear temporal filter is studied to investigate the quantization error between the filtered output and its original signal. Reduction of the quantization error verifies that using information from surrounding frames can enhance the quality of the current frame. Next, a non-linear fuzzy spatio-temporal filter is proposed to adapt to the characteristics of the coding artifacts. The dissertation also proposes a novel metric for evaluating the flickering artifacts. For applications on coding, these spatio-temporal filters are used in the encoding loop as the enhanced reference frame. They are then optimized to maximize their performance in artifact reduction. For special cases when filter coefficient for the pixel of interest is set to zero, the filter becomes an estimator or an interpolator. The dissertation extends the discussion for the case of implementing the optimal estimator in the encoding phase using multi reference frames. Finally, an edge-directed interpolator is studied and used in data pruning based compression, which can help reducing the bit-rate of the encoded bit-stream. This interpolator is applied to determine the most effective way in dropping the data before compression and to reconstruct the pruned signal back to its original form.

Book excerpt: Change Detection and Image Time Series Analysis 1 presents a wide range of unsupervised methods for temporal evolution analysis through the use of image time series associated with optical and/or synthetic aperture radar acquisition modalities. Chapter 1 introduces two unsupervised approaches to multiple-change detection in bi-temporal multivariate images, with Chapters 2 and 3 addressing change detection in image time series in the context of the statistical analysis of covariance matrices. Chapter 4 focuses on wavelets and convolutional-neural filters for feature extraction and entropy-based anomaly detection, and Chapter 5 deals with a number of metrics such as cross correlation ratios and the Hausdorff distance for variational analysis of the state of snow. Chapter 6 presents a fractional dynamic stochastic field model for spatio temporal forecasting and for monitoring fast-moving meteorological events such as cyclones.

Available in PDF, EPUB and Kindle. Book excerpt: In four chapters and an introduction, this book systematically helps readers understand the development of the Geographical Sciences both in China and in the world during the past 30 years. Through data analysis of methodologies including CiteSpace, TDA, qualitative analysis, questionnaires, data mining and mathematical statistics, the book explains the evolution of research topics and their driving factors in the Geographical Sciences and its four branches, namely Physical Geography, Human Geography, Geographical Information Science and Environmental Geography. It also identifies the role of the Geographical Sciences in the analysis of strategic issues such as global change and terrestrial ecosystems, terrestrial water cycle and water resources, land change, global cryosphere evolution and land surface processes on the Tibetan Plateau, economic globalization and local responses, regional sustainable development, remote sensing modelling and parameter inversion, spatial analysis and simulation, and tempo-spatial processes and modelling of environmental pollutants. It then discusses research development and inadequacy of Chinese Geographical Sciences in the above-mentioned topics, as well as in the fields including Geomorphology and Quaternary environmental change, Ecohydrology, ecosystem services, the urbanization process and mechanism, medical and health geography, international rivers and transboundary environment and resources, detection and attribution of changes in land surface sensitive components, and uncertainty of spatial information and spatial analysis. It shows that the NSFC has driven the development in all these topics and fields. In addition, the book summarises trends of the Geographical Sciences in China and the research level in major countries of the world through an overview of geographical education in colleges and universities, the analysis of publications, citations and author networks of SCI/SSCI and CSCD indexed articles, and the description of Sino-USA, Sino-UK and Sino-German cooperation. This book serves as an important reference to anyone interested in geographical sciences and related fields.
