“…In Figs.1-2 the targets are two persons and the clutter of the TBS is due to the forest background. If a target in an image stands against a sufficiently cluttered background, then to calculate the local contrast one measures the brightness of the background b I as an average of the brightness values along the horizontal line segment of the length equal to the half-width of the target in the vicinity of the target on both its sides [8]. Such a way of measurement is equivalent to the observation of the target in the regime when the image is zoomed until the target is observed against a more or less uniform local background.…”

“…The images shown in Table 2, where targets are observed against a uniform background are illustrative examples of a case when the saliency of the target reduces to its visibility. Detailed characterization of the target visibility for these partial and fused images can be found in our previous paper [3]. For these reasons, we do not explore the studies on their conspicuity and saliency, instead, further in the text, we focus on the characterization of the images with a cluttered background, shown in Figs.…”

Our analysis of the available literature on quantitative quality indices characterizing the visibility, conspicuity, and saliency of the objects in an image reveals that the used approaches do not fit the military needs, in particular those required by the target sightseeing systems of armored vehicles. Their main drawback is that these indices are not target-oriented. The long elapsed time needed for their evaluation is another inconvenience, making them inapplicable for military purposes, which in most cases require a real-time response. Special target-oriented image quality indices are needed for military applications. In this paper, we propose the very such target-oriented normalized visibility, conspicuity, and saliency indices and corresponding methods for their measurements. Comparison of the times elapsed for the generation of saliency maps by the analyzed literature methods and the adequacy of the saliency scores produced by them with those for the saliency index, proposed in this paper, reveals that the computation with our approach is several orders of magnitude faster than for the prototype methods available in the literature while providing comparable adequacy of the measured target-oriented image quality indices.
