【摘要】 目的根据足趾图像的模糊性和不同形状之间的过渡性,提出基于模糊理论的计算机足趾形状模糊识别方法。方法根据形状特征值的统计规律,分别从角度特征值、长度特征值两个不同的影响指标构造属于不同形状的隶属函数;然后以此隶属度作为单因数评判因子,采用综合评判和隶属度最大原则利用计算机对足趾图像形状进行自动识别。结果由于这种模糊识别方法更能客观、准确地反映出足趾的不同形状,所以使得计算机总体自动识别率达到91.5%。结论足趾形状的模糊自动识别方法在实际应用中是行之有效的。更多还原

【Abstract】 According to the fuzzy feature of toe image and transition character of different toe shape, a method of toe shape fuzzy recognition is proposed based on fuzzy theory. First of all, it constructs effectively the subjection functions of different toe shape as statistical rule of the eigenvalue of angle degree and length, and the value of subjection function is considered single judge factor. Then fuzzy comprehensive evaluation and the principle of maximum subjection degree are used to recognize toe shape. The results of experiments show it is a feasible method approaching to toe shape recognition.更多还原
