摘要：

We investigate the potential of multiscale product as a measure for change detection in difference images. The rationale relies on exploiting the cross-scale correlation characteristics of signal and noise. We use Monte Carlo simulations to assess the detection and localization performances of the multiscale product for the detection of linear features of different widths. Comparisons are made with change detection based on single scale as well as other multiscale combination rules. Preliminary simulation results show that, overall, a good performance balance is obtained for change detection over the range of SNRs and line widths investigated.
