A method of difference sensing. A first step involves producing a reference image using temporal averaging and spatial averaging. A second step involves producing a test image. A third step involves computationally comparing the reference image with the test image to arrive at a resulting difference image. The temporal averaging and spatial averaging effectively isolates in the difference image coherent changes imbeded in a complex and rapidly changing environment from transient changes inherent to the complex and rapidly changing environment.
