Studies on Classification of Remote Sensing Image Processing Based on Artificial Neural Network

With the development of the theory about Artificial Neural Network(ANN)system,the neural network technology is becoming increasingly an effective means of classification processing of remote sensing digital images and beginning to replace the Maximum Likelihood Classifier(MLC).This paper mainly discusses the method of BP Neural Network that have been very effectively applied to remote sensing digital image processing and presents the classification algorithm of BP Neural Network developed using Matlab.At last,its classification accuracy is compared to maximum likelihood classifier(Bayes).The results show that the classification method based on BP neural network is an effective approach.
