INDEX TERMS Hyperspectral unmixing, autoencoder, deep learning, neural network, spectral angle distance, endmember extraction. I. INTRODUCTION Hyperspectral imaging is a rapidly growing ˝eld of remote sensing that has contributed signi˝cantly to Earth observa-tions. In hyperspectral imaging, a special kind of sensor
Spectral unmixing is an important task in hyperspectral image processing for separating the mixed spectral data pertaining to various materials observed individual pixels. Recently, nonlinear spectral unmixing has received particular attention because a linear mixture is not appropriate under many conditions. However, existing nonlinear unmixing approaches are often based on specific ...
This paper proposes a nonnegative matrix factorization ( NMF) inspired sparse autoencoder (NMF-SAE) for hyperspectral unmixing that is not only physically interpretable and flexible but also has higher learning capacity with fewer parameters. Hyperspectral unmixing is an important tool to learn the material constitution and distribution of a scene. Model-based unmixing methods depend on well ...

In this paper, we propose a deep spectral convolution network to unmix hyperspectral data with pre-computed endmembers. Throughout the paper, we introduce three critical contributions for the unmixing problem. First, instead of a single layer fully-connected linear operation, a network that is composed of several spectral convolution layers ...
Hyperspectral Unmixing Using a Neural Network Autoencoder. In this paper, we present a deep learning based method for blind hyperspectral unmixing in the form of a neural network autoencoder. We show that the linear mixture model implicitly puts certain architectural constraints on the network, and it effectively performs blind hyperspectral ...
DAEN: Deep Autoencoder Networks for Hyperspectral Unmixing. Abstract: Spectral unmixing is a technique for remotely sensed image interpretation that expresses each (possibly mixed) pixel as a combination of pure spectral signatures (endmembers) and their fractional abundances. In this paper, we develop a new technique for unsupervised unmixing ...

A hyperspectral image (HSI) contains hundreds of spectral bands, which provide detailed spectral information, thus offering an inherent advantage in classification. The successful launch of the Gaofen-5 and ZY-1 02D hyperspectral satellites has promoted the need for large-scale geological applications, such as mineral and lithological mapping (LM).

Model-Based Deep Autoencoder Networks for Nonlinear Hyperspectral Unmixing. 04/17/2021 ∙ by Haoqing Li, et al. ∙ 0 ∙ share . Autoencoder (AEC) networks have recently emerged as a promising approach to perform unsupervised hyperspectral unmixing (HU) by associating the latent representations with the abundances, the decoder with the mixing model and the encoder with its inverse.
Beyond the alone autoencoder-like architecture, EGU-Net is a two-stream Siamese deep network, which learns an additional network from the pure or nearly-pure endmembers to correct the weights of another unmixing network by sharing network parameters and adding spectrally meaningful constraints (e.g., non-negativity and sum-to-one) towards a ...central coast car accident fatalityjdownloader 2 premium accounts reddit
