摘　　要：将分形的概念应用于腐蚀形貌图像的特征提取,计算扫描得到的实海腐蚀试片图像的分形维数、广义维数、面积因子和空隙特征,并作为分析诊断系统的输入,用模糊模式识别理论建立了基于图像分形特征的腐蚀形貌图像诊断系统,可以由图像的分形特征值判断金属的表面腐蚀形貌。The theory of fractal geometry is used to analyze the corrosion morphology images, which were acquired by scanner. The fractal dimension, generalized dimension, area factor and laucinarity of metallic corrosion images of samples that exposed in seawater were calculated. Taking the obtained characters of metallic samples and their corrosion modality as the knowledge base, the diagnosing system identifying corrosion modality of metallic material in seawater was established according to the theory of fuzzy pattern recognition. The morphology of corrosion images can be identified by acquired fractal characters.
