Sum the elements in Z_detect and divide by the total number of trials to obtain the empirical false-alarm rate. pfa = sum (Z_detect)/Ntrials. pfa = 0.0013. The empirical false-alarm rate is 0.0013, which corresponds closely to the desired false-alarm rate of 0.001.

WebOct 27, 2024 · Abstract: A key challenge of infrared small object segmentation (ISOS) is to balance miss detection (MD) and false alarm (FA). This usually needs ``opposite'' strategies to suppress the two terms, and has not been well resolved in the literature. In this paper, we propose a deep adversarial learning framework to improve this situation.
