An attempt has been made in this paper to classify multispectral images using customized particle swam optimization. To reduce the time consumption due to increase in dimensionality of multispectral imagery a preprocessing is done using feature extraction based on decision boundary. The customized particle swam optimization then works on the reduced(More)
—We present a new filtered-backprojection (FBP) type image reconstruction method for synthetic aperture radar (SAR) that exploits multi-path in the presence of a perfectly reflecting wall. The new method is designed to take advantage of multiple scattering and incorporates the multiple scattered waves in the image reconstruction process enhancing the(More)
