Image sequences produced by, e.g., electro-optical sensors are being used increasingly for continuous quality monitoring and surveillance. This letter considers the important problem of multiframe change point detection of signals with unknown dynamics. We propose a new CUSUM-based (cumulative SUM) detector for detecting noise-obscured signals in a sequence… CONTINUE READING
