WebIt is shown that the minimax approach permits the design of a rich variety of matched filter and subspace detectors that vary in the degree of robustness and sensitivity. A minimax methodology for formulating adaptively robust and sensitive matched filter and subspace detectors is provided, where the signal and interference of structured noise are partially … WebMay 3, 2011 · Abstract. A matched filter is a linear filtering device developed for signal detection in a noisy environment. The matched filtering technique can be directly employed in image registration for the estimation of image translation. The transfer function of a classic matched filter is the Fourier conjugate of the reference image, divided by the ...
