چکیده
Floods, as one of the natural hazards, can affect environment, damage infrastructures, and threaten human lives. Due to climate change anthropogenic activities, floods occur in high frequency all over world. Therefore, mapping flood areas is prime importance disaster management. This research presents a novel framework for area based on heterogeneous remote sensing (RS) datasets. The proposed fuses synthetic aperture radar (SAR), optical, altimetry datasets areas, it applied three main steps: (1) preprocessing, (2) deep feature extraction multiscale residual kernel convolution neural network’s (CNN) parameter optimization by fusing datasets, (3) detection trained model. exploits two large-scale flooded Golestan Khuzestan provinces, Iran. results show that methodology has performance detection. visual numerical analyses verify effectiveness ability method detect with an overall accuracy (OA) higher than 98% both study areas. Finally, efficiency designed architecture was verified hybrid-CNN 3D-CNN methods.

متن کاملWeighted Convolutional Neural Network Ensemble
We introduce a new method to combine the output probabilities of convolutional neural networks which we call Weighted Convolutional Neural Network Ensemble. Each network has an associated weight that makes networks with better performance have a greater influence at the time to classify in relation to networks that performed worse. This new approach produces better results than the common metho...
متن کاملA Convolutional Neural Network based on Adaptive Pooling for Classification of Noisy Images
Convolutional neural network is one of the effective methods for classifying images that performs learning using convolutional, pooling and fully-connected layers. All kinds of noise disrupt the operation of this network. Noise images reduce classification accuracy and increase convolutional neural network training time. Noise is an unwanted signal that destroys the original signal. Noise chang...
متن کاملTree-CNN: A Deep Convolutional Neural Network for Lifelong Learning
In recent years, Convolutional Neural Networks (CNNs) have shown remarkable performance in many computer vision tasks such as object recognition and detection. However, complex training issues, such as “catastrophic forgetting” and hyper-parameter tuning, make incremental learning in CNNs a difficult challenge. In this paper, we propose a hierarchical deep neural network, with CNNs at multiple ...
