Book Description
This report describes an approach for automatic feature detection from fusion of remote sensing imagery using a combination of neural network architecture and the Dempster-Shafer (DS) theory of evidence. Deterministic or idealized shapes are used to characterize surface signatures of oceanic and atmospheric fronts manifested in satellite remote sensing imagery. Raw satellite images are processed by a bank of radial basis function (RBF) neural networks trained on idealized shapes. The final classification results from the fusion of the outputs of the separate RBF. The fusion mechanism is based on DS evidential reasoning theory. The approach is initially tested for detecting different features on a single sensor and extended to classifying features observed by multiple sensors.

Book Description
Dempster-Shafer theory offers an alternative to traditional probabilistic theory for the mathematical representation of uncertainty. The significant innovation of this framework is that it allows for the allocation of a probability mass to sets or intervals. Dempster-Shafer theory does not require an assumption regarding the probability of the individual constituents of the set or interval. This is a potentially valuable tool for the evaluation of risk and reliability in engineering applications when it is not possible to obtain a precise measurement from experiments, or when knowledge is obtained from expert elicitation. An important aspect of this theory is the combination of evidence obtained from multiple sources and the modeling of conflict between them. This report surveys a number of possible combination rules for Dempster-Shafer structures and provides examples of the implementation of these rules for discrete and interval-valued data.

Book Description
Artificial neural networks (ANNs) and evolutionary computation methods have been successfully applied in remote sensing applications since they offer unique advantages for the analysis of remotely-sensed images. ANNs are effective in finding underlying relationships and structures within multidimensional datasets. Thanks to new sensors, we have images with more spectral bands at higher spatial resolutions, which clearly recall big data problems. For this purpose, evolutionary algorithms become the best solution for analysis. This book includes eleven high-quality papers, selected after a careful reviewing process, addressing current remote sensing problems. In the chapters of the book, superstructural optimization was suggested for the optimal design of feedforward neural networks, CNN networks were deployed for a nanosatellite payload to select images eligible for transmission to ground, a new weight feature value convolutional neural network (WFCNN) was applied for fine remote sensing image segmentation and extracting improved land-use information, mask regional-convolutional neural networks (Mask R-CNN) was employed for extracting valley fill faces, state-of-the-art convolutional neural network (CNN)-based object detection models were applied to automatically detect airplanes and ships in VHR satellite images, a coarse-to-fine detection strategy was employed to detect ships at different sizes, and a deep quadruplet network (DQN) was proposed for hyperspectral image classification.

Book Description
Machine and deep learning techniques for content extraction of satellite images utilize artificial intelligence and neural networks to analyze and extract information from satellite imagery. These techniques can be used for a variety of applications, such as image classification, object detection, optical character recognition (OCR), and semantic segmentation. Convolutional Neural Networks (CNNs) are commonly used for image classification and object detection tasks. These networks are designed to process and understand images by analyzing the spatial relationship between pixels. They are composed of multiple layers, with each layer analyzing a different level of detail in the image. CNNs are particularly effective at identifying patterns and features in satellite images, such as roads, buildings, and vegetation. Recurrent Neural Networks (RNNs) and Long Short-term Memory (LSTM) networks are particularly useful for tasks that require the analysis of sequential data, like time series data. They are particularly useful in land cover change detection, change detection and time series analysis of satellite images. Semantic segmentation is the process of classifying each pixel in an image to a particular class, and it can be achieved using Fully Convolutional Networks (FCN) and U-Net architecture. This technique is particularly useful for identifying different land cover classes in satellite images, such as urban, agricultural, and natural areas. Generative Adversarial Networks (GANs) are used for creating synthetic images or super resolution of images. These are particularly useful for creating synthetic data for training and testing deep learning models for satellite images. Transfer learning is a technique that allows a pre-trained model to be fine-tuned for a specific task. This can be used to improve the accuracy of image classification and object detection tasks by using a pre-trained model as a starting point. In summary, machine and deep learning techniques for content extraction of satellite images involve using neural networks and computer vision techniques to analyze and extract information from satellite imagery. These techniques can be used for a variety of applications, such as image classification, object detection, and semantic segmentation, and can improve the accuracy and efficiency of extracting information from satellite images. to process and understand images by analyzing the spatial relationship between pixels.
