- Description:
- In this work, we compare the continuous wavelet transform (CWT) energy density template matching to a standard technique, for the classification of targets in synthetic aperture radar (SAR) imagery. We also evaluate the robustness of the two template matching schemes against reduced signal-to-clutter ratios (SCR). The data we are using was obtained from the MSTAR (public) data base. The comparison is performed in two domains of the image, namely the linear and logarithm domains, where each domain has a particular characteristic that either enhances or suppresses certain target features against the background clutter. Our method specifically uses target features obtained by computing the energy densities of the image at various relevant scales and orientations for both the train and test set, where the classification of targets is accomplished by the determination of the maximum correlation of a test image to various templates generated with the train set. The robustness of the template matching techniques is determined by the probability of correct classification as the SCR is reduced.
