Abstract:

Based on the fact that the recognition of a target depends mainly on the structure feature for human vision, the structure of the edge background clutter metric is proposed, by describing the similarity between background and target by their difference in the distribution of the edge structure. Compared to the others, it is available for various scenes by statistically computing the properties of the target and background's structure to emphasize the importance of the structure and weaken the influence of scene illumination on target recognition. Experiment shows that its prediction correlates well with the detection probability of human visual systems.

Key words: target acquisition performance, target recognition, background clutter, structure feature, distribution of edge orientation
