This study chose Quick Bird satellite image with high resolution and spatial information as the resource origin of image classification and used Support Vector Machine (SVM) to achieve the goal on classification. We present two of spatial information which are Principal Component Analysis (PCA) image using 2-D discrete wavelet transform (DWT), and image segmentation. The DWT is used to generate spatial...
This paper address the problem of change detection in very high resolution remote sensing images. To that end, we define a measure of the observed change based on the distribution of the coefficients issued from a wavelet transform, taking care to be rotation invariant. The dissimilarities are obtained through the Kullback-Liebler distance and a change features vector is defined from all the distances...
