In this paper,we propose a new method to evaluate infrared distortion camouflage effect. We adoptMoravec operator to extract the feature points of the images of target taken before and after it is camouflaged, and then we use the imp roved Hausdorff distance to measure the Hausdorff distance between the feature points sets. The greater the distance is, the better the camouflage effect is. The other necessary aspect evaluating the camouflage effect is to measure the similarity of the infrared radiation character between the camouflaged target and its adjacent background. The similaritymeasure is based on the fuzzyMinkowski distance, so we have to transform the images into fuzzy sets at first. The observation is that the smaller the distance between the infrared image of the camouflaged target and its adjacent background is, the greater the similarity is between them and the better the infrared camouflage effect is. In the two ways,we can evaluate the infrared distortion camouflage effect of the camouflaged target quickly.
