From: Masking of Time-Frequency Patterns in Applications of Passive Underwater Target Detection
Cartoon of a pair of time-frequency cells (
and 
) placed in a time-frequency window (surrounded by the thick dotted line) is shown using two different gray shades. Panels (a) and (b) show relative location of TFCs used for dissimilarity estimation of BB and NB changes, respectively. The red filled circles in the middle of the TF cells correspond to the mean values of time (tc) and frequency fc of respective TF window.
