Ebook: MultiSensor and MultiTemporal Remote Sensing

This book elaborates fuzzy Machine Learning and Deep Learning models for single class mapping from multi-sensor, multi-temporal remote sensing images while handling mixed pixels and noise. It also covers the ways of pre-processing and spectral dimensionality reduction of temporal data. Further, it discusses the ‘individual sample as mean’ training approach to handle heterogeneity within a class. The appendix section of the book includes case studies such as mapping crop type, forest species, and stubble burnt paddy fields.

There are numerous Machine Learning models available for use in a variety of applications. Machine Learning classifers can fall into statistical categories such as c-Means, maximum-likelihood classifers, and decision-tree categories, such as random forest and Classifcation and Regression Tree (CART). Fuzzy c-Means (FCM), Possibilistic c-Means (PCM), Noise Clustering (NC), and Modifed Possibilistic c-Means (MPCM) are examples of fuzzy-logic algorithms. The Machine Learning model should be chosen in such a way that it can deal with mixed pixels, non-linearity between classes, and noisy pixels. Machine Learning models should be able to map a single class of interest, which has a wide range of applications, where only one class of interest needs to be mapped from remote-sensing data. Machine Learning models should also be able to deal with heterogeneity within classes, which is caused by the fact that training data for each class is not homogeneous. So, in this section, fuzzy classifers are discussed, which addresses the raised concerns. In this chapter, mathematical formulas and algorithms of the fuzzy-based algorithms have been explained. The description starts with Fuzzy c-Means (FCM), moves on to Possibilistic c-Means (PCM) and Noise Clustering, and then Modifed Possibilistic c-Means (MPCM) is described.
