This paper proposes an auto-focusing noise suppressor (AF-NS) for cellphone movies. For relatively small clicks compared to the target signal, it consists of magnitude suppression and complementary phase modification. The input signal is analyzed in the frequency domain to detect and preserve important spectral components including peaks and their vicinities. All other components are suppressed to the environmental signal level that is estimated during absence of the important components… CONTINUE READING
