A note on lag detection of digital ghost component using mean cepstrum for partial image

摘要

In this paper, we deal with the lag detection of digital ghost component using mean cepstrum for partial image. First we describe the definition of power cepstrum. Secondly we show a procedure of producing a composite signal which consists of original and ghost components. Then we propose two basic methods of detecting the lag of ghost component from the composite signal. The computer simulation results for some test images show that the lag of ghost component can be effectively detected by our methods.
