The wall rock alteration should be reflected in the remote sensing images in the form of spectral information. By the special information they reflected on the spectrum, we can extract the alteration information by using remote sensing image processing methods, in order to get the purpose of finding the mine. Usually, the mineralized alteration in one area is not the result of only one alteration,...
The principle of Support Vector Machine based on spot is to choose an appropriate scale to split the image into a series of segmentation, according to certain strategy using spectral information. And this principle ensures the spectral features of the majority of patch pixel similar. This method gathers statistics of each pixel value in the spot and obtains the mean value of each band to replace the...
We use sequential projection pursuit method to analyze all kinds of projection index, and put forward the projection index and optimized search algorithm which is fit for hyperspectral image data. We develop sequence in VC++ environment, take dimensionality reduction and feature extraction experiment on two kinds of hyperspectral image data, and also do the accuracy evaluation. We can find from the...
