摘要
由于现代化社会中涉及大量多媒体信息的处理,使得人们对于信息分类系统的要求也逐步提高。为此提出了多媒体信息分类中的边缘模糊确定方法仿真。首先,提取多媒体信息中的增益特征,利用一阶和二阶导数曲线判断信息边缘点的有效性及变化关系,并使用高斯函数对得到的导数关系提取出边缘模糊算子,确定不同类型信息的边缘点,以信息特征中心为基准,根据信息阈差完成多媒体信息类型的最佳划分,使用隶属函数和模糊空间关系寻求分类最优解。最后,通过仿真与其它方法对比表明所提方法具有更高的精准性,多媒体信息分类结果最佳,且分类计算过程相较便捷,可被广泛推广应用。
Due to the processing of massive multimedia information in modern society,the requirements for information classification system are gradually improved.Therefore,the simulation of edge fuzzy determination method in multimedia information classification was proposed.Firstly,the gain features of multimedia information were extracted.The effectiveness and variation of information edge points were judged by the first-order derivative curve and second-order derivative curve.The Gaussian function was used to extract the edge fuzzy operator from the derivative relation,and then the edge points of different types of information were determined.Based on the information feature center,the optimal classification of multimedia information types was completed by the information threshold difference.The relation between membership function and fuzzy space was used to find the optimal solution.Finally,the simulation results show that the proposed method has higher accuracy.In addition,the multimedia information classification result is the best,and the calculation process is relatively convenient,so this method can be widely applied.
