摘    要:图像的边缘检测中,非优化梯度阈值选择的不当会造成某些边缘点的丢失;而模糊阈值方法,需占用大量存储空间来搜索参数的最优组合.针对以上问题,本文在模糊理论的基础上,并结合红外梯度图像的特点,提出了一种基于模糊联合误差的红外图像边缘检测方法.本文首先通过改进的Sobel算子构造出红外图像的梯度图,在对其进行模糊划分的基础上计算区域模糊度,最后通过对区域联合误差的比较,确定模糊区域中像素点的隶属,实现边缘提取.与传统的基于梯度的边缘检测算法及最大模糊熵算法进行了对比实验.结果表明,该方法用于红外图像边缘检测时,能够在更短的处理时间内,保留更多的边缘信息.

关 键 词:边缘检测  红外图像  模糊划分  模糊区域  联合误差

Abstract:In the field of the edge detection of infrared image,the inappropriate selection of no-optimized gradient threshold caused some losses of edge points;Fuzzy threshold algorithm is implemented to search the optimal combination of the fuzzy parameter,which occupies large memory size.Considering the difficulties of the above,a novel approach for edge detection basing upon fuzzy Association Error is presented in the paper.First,the gradient image is constructed by the improved Sobel operator,and then the area fu...
Keywords:edge detection  infrared image  fuzzy partition  association error  fuzzy area
