Landmine discrimination using wavelet decomposition and weighted density distribution functions
"Landmine detection using hand-held units is a difficult problem due to varying type and composition of metals in landmines. This research explores spatially distributed features to discriminate landmines from other harmless objects. The feature calculation involves the wavelet decompoosition of Metal Detector (MD) energy sequences to obtain the approximate and detailed coefficients, and correlation of these coefficients with Weighted Density Distribution (WDD) functions. The features calculated are evaluated on a standard back propagation neural network on real data sets with more than 1500 mine encounters of varying shape, size and metal content. The effectiveness of wavelet decomposition and WDD functions is investigated"--Abstract, leaf iii.
