Research on High Resolution Remote Sensing Image Classification based on Decision Tree
Abstract Resolution remote sensing image has been greatly improved, the spectral characteristics of the image feature not only richer, but also more prominent internal structure, texture, edges and other surface features of information, high-resolution remote sensing satellite data in the field of remote sensing applications It will play an increasingly large role.
In this paper, the characteristics of high resolution satellite images to study high-resolution image classification method. Remote sensing image classification methods are currently used more maximum likelihood method, decision tree, neural network classification algorithm method, wherein the decision tree method because of its ease of calculation, flexible, intuitive, and can accurately express resolution rate of remote sensing image information, more and more attention of researchers. The thesis of the decision tree classification algorithm research, and the CART decision tree classification algorithm classifies QuickBird imagery and classification results with remote sensing image classification commonly used in the maximum likelihood method were compared and evaluated.
In this paper, there are pictures 7 pieces, a table 6,19 chapter references.
