An example of how gray-level co-occurrence matrix (GLCM) trackability metric (TM) can be used to evaluate a concealing countermeasure is presented. In this example the effect of multispectral waterfog as a countermeasure for an armored vehicle is evaluated. The results are also compared to results from a correlation tracker. A careful analysis of GLCM TM results showed that multispectral waterfog is effective against a target tracker. This analysis includes a comparison to an actual tracker simulation, a contrast analysis, and an analysis of the uncertainty histograms used in the GLCM TM calculation.
