A novel algorithm of infrared image enhancement based on fuzzy sets theory is proposed in this paper. First, Pal and King's algorithm was analyzed and its drawbacks were summarized. Then, the local fuzzy entropy of image was calculated for determining the threshold. On this basis, the new membership function of fuzzy was defined and infrared image was enhanced effectively by fuzzy enhancement transformation,...
Non-universality and fuzziness of fractal would bring detection error when utilizing fractal feature to detect target in complex background. In this paper, a novel target detection algorithm based on fuzzy enhanced fractal feature is proposed. After the fractal feature named area measurement was estimated according to self-similarity of fractal, the new membership function of fuzzy sets based on the...
