Spatial-temporal difference method for detecting small moving targets in visible image background clutter

The visible image background clutter is correlative in space and time domain. To detect small moving targets in complex visible image background clutter, the spatial-temporal difference method is presented. Based on the visible image sequences model, the characteristic and difference of targets, background and noise is analysis qualitatively. With these, the spatial-temporal difference method (STDM) for background suppression is presented and also it´s realization via assembly line and pipeline scheme is given. Many experiments prove the availability in practice
