针对局部模糊区域检测与分割,提出一种基于再模糊和奇异值分解的局部模糊检测方法。首先,对待检图像进行高斯模糊和图像连续分块,对分块图像进行奇异值分解;其次,对奇异值向量进行指数函数拟合,得到待测和再模糊图像的奇异值曲线,分别... 针对局部模糊区域检测与分割,提出一种基于再模糊和奇异值分解的局部模糊检测方法。首先,对待检图像进行高斯模糊和图像连续分块,对分块图像进行奇异值分解;其次,对奇异值向量进行指数函数拟合,得到待测和再模糊图像的奇异值曲线,分别计算拟合曲线的积分并作差,将差值差异性作为描述模糊的特征值;最后,利用Canny边缘检测算法完成图像分割,并利用最大、最小滤波器和相关形态学处理对边缘内部区域进行填充。实验结果表明:该方法可以有效地完成局部模糊区域的检测和分割,同时对纹理平坦区域的识别同样有效。 展开更多

On the basis of defining the concept of rural public product supply, the weaknesses of the supply mechanism of rural public product are analyzed. The shortages of rural public product supply lead to the difficult ties in developing agriculture and rural economy; enriching farmers and narrowing the urban and rural income gap. Problems in rural public product supply are further analyzed. Firstly, the national finance used in agriculture is low. Secondly, farmers are not separated from decision system and the beneficiaries separate from the decision-makers. Thirdly, farmers are not fully treated as civilians. Fourthly, rural areas lack the selection and supervision mechanism of public product. The ideas and countermeasures on perfecting rural public product are put forward from the perspective of main beneficiaries. The supply of rural public product should take intensifying the self development capability of farmers as core; farmers should actively participate in the making the rural public product decision and fight for their right to say. Farmers should unit together through organizations to improve the organizational level. Farmers should actively participate in trainings on them and try to get the updated information from the local government. The village collective should protect the supply of rural public product. 展开更多
