An expert system approach for image classification according to expert knowledge about best sites for vegetation classes is described. Uncertainty management is solved by a certainty factor approach. The numerical and symbolic data fusion is viewed as an updating process. The fusion approach is then described. A neural classifier applied to image data is the first source. A set of fuzzy neural networks representing expert knowledge constitutes the second source. A conjunctive combination based on evidence theory is applied. Finally, a possibility theory-based pooling aggregation rule is presented. These three approaches are applied to a vegetation classification problem.

An experimental analysis of the use of different neural models for the supervised classification of multisensor remote-sensing data is presented. Three types of neural classifiers are considered: the Multilayer Perceptron, a kind of Structured Neural Network, proposed by the authors, that allows the interpretation of the network operation, and a Probabilistic Neural Network. Furthermore, the k-nearest neighbour statistical classifier is also considered in order to evaluate the validity of the aforementioned neural networks, as compared with that of classical statistical methods. The results provided by the above classifiers are compared.

The paper reviews the most recent proposals on the integration of fuzzy and neural networks techniques. First, it focuses on the strategies developed and employed for the fuzzification of neural network architectures. Then it applies an unsupervised fuzzy architecture to the analysis of remotely sensed data and compares the results with those obtained by means of a conventional neural model.

A hybrid approach to fuzzy land cover mapping

引用

PATTERN RECOGNITION LETTERS 1996年第13期17卷 1399-1410页

作者： Binaghi, E Brivio, PA Ghezzi, P Rampini, A Zilioli, E CNR TELERILEVAMENTO IRRSI-20131 MILANITALY

We propose here a fuzzy hybrid methodology for the classification, conceived as a cognitive process, of remote sensing images. The salient aspect of the approach is the combined use of different techniques: the linear mixture model, a supervised fuzzy statistical classifier and a fuzzy labeling technique, An application for the identification of rice crops in a Landsat Thematic Mapper image has been developed with the aim of experimentally evaluating the performance of the overall strategy in a real domain where fuzzy membership to classes are essential in class discrimination, The results have then been compared with those obtained by means of the Maximum Likelihood classifier.

Active fusion - A new method applied to remote sensing image interpretation

引用

PATTERN RECOGNITION LETTERS 1996年第13期17卷 1349-1359页

Today's computer vision applications often have to deal with multiple, uncertain and incomplete visual information. In this paper, we introduce a new method, termed ''active fusion'', which provides a common framework for active selection and combination of information from multiple sources in order to arrive at a reliable result at reasonable costs. The implementation of active fusion on the basis of probability theory, the Dempster-Shafer theory of evidence and fuzzy sets is discussed. In a sample experiment, active fusion using Bayesian networks is applied to agricultural field classification from multitemporal Landsat imagery. This experiment shows a significant reduction of the number of information sources required for a reliable decision.

proceedings of the 1999 IEEE international Geoscience and remote sensing Symposium (IGARSS'99) 'remote sensing of the Systems Earth - A Challenge for the 21st Century'

Single and repeat-pass SAR interferometry appears to be a new promising tool for a wide variety of applications. Recent studies have already shown that interferometric correlation, e.g. coherence and intensity images can be coupled to improve thematic land classification. The techniques used to combine and analyze such information are mainly based on thresholding schemes and classical maximum likelihood, although SAR data are not normally distributed. The main objective of this work is the validation of soft computing techniques for the analysis of ERS SAR intensity images combined with interferometric correlation images. A multi-modular neural system, composed by unsupervised and supervised architectures was applied to the analysis of one tandem ERS 1/2 pair, 27-28 August 1995, and one single ERS2 image, 24 July 1995.

In this paper, the remote sensing classification results of urban land of Trading district of Shanghai, China in the years of 1995 and 2001 were employed as expatiated case. The theory of sampling with the integration of remote sensing technique and spatial overlaying analysis for monitoring urban land change has been investigated. The dynamic urban land sampling framework (DULSF) is first investigated, in which three parts were built and implemented that: (1) a dynamic changed urban land regionalization (DCULR) in the case area based on the dynamic urban land change degree (ULCD);(2) a dynamic spatial information and sampling framework (DSISF) based on different urban land change rate;and (3) a dynamic changed urban land sampling units (DCULSU). And a crucial metric that dynamic urban land change degrees of sampling unit (DULCDSU) was proposed in the dynamic urban land sampling framework. A dynamic urban land change sampling (ULCS) scheme was then generated while the valid samples were determined, sample distribution strategy was disposed, and accuracy prior and post assessment was carried out. Finally, the dynamic urban land change sampling data is summarized for case area. Some conclusive remarks are revealed that: (1) the theory of dynamic spatial information and sampling framework in this paper is feasible to control the sampling operation, and (2) the proposed spatially sampling scheme is efficient based on the remote sensing and spatial overlaying analysis.

Spatio-temporal analysis is a process for city development with growing population and economy for better implementation of planning policies with advance technology. In this research work, three dates (1995, 2005 & 2016) satellite images were used to mapping and monitoring of Moscow region, Russia. This study focuses on the further classification of the study area into different categories on the basis of use and association by implementing a rule-based classification system on remotely sensed data. This research provides useful and up-to-date information to local land use planners, managers and policy-makers to step up towards sustainable development in Moscow region, Russia.

Automatic gray scale correction of video data

Automatic gray scale correction of video data

5th Int. workshop on Digital Image Processing and Computer Graphics (DIP-94)

作者： Chochia, P.A. Inst. for Information Transmission Problems Moscow Russia

Automatic gray scale correction of captured video data (both still and moving images) is one of the least researched questions in the image processing area, in spite of this the question is touched almost in every book concerned with image processing. Classically it is related to the image enhancement, and frequently is classified as histogram modification techniques. Traditionally used algorithms, based on analysis of the image histogram, are not able to decide the problem properly. The investigating difficulties are associated with the absence of a formal quantitative estimate of image quality - till now the most often used criteria are human visual perception and experience. Hence, the problem of finding out some measurable properties of real images, which might be the basis for automatic building of gray scale correction function (sometimes identified also as gamma-correction function), is still unsolved. In the paper we try to discern some common properties of real images that could help us to evaluate the gray scale image distortion, and, finally, to construct the appropriate correction function to enhance an image. Such a method might be sufficiently used for automatic image processing procedures, like enhancing of medical images, reproducing of pictures in the publishing industry, correcting of remote sensing images, preprocessing of captured data in the computer vision area, and for many other applications. The question of complexity of analysis procedure becomes important when an algorithm is realized in real-time (for example in video input devices, like video cameras).
