    The fuzzy C-Means (FCM) clustering is widely used in image segmentation,but the random determination of initial clustering centers of the FCM clustering is likely to generate incorrect segmentation of an image.To avoid the such deficiency,a method of choosing initial clustering centers in the FCM clustering for image segmentation is proposed.The method determines the number for the image clustering by means of the number of the peaks in the two-dimensional histogram of an image comprised of gray values of pixels and mean values of their neighborhoods.Then the K-means clustering is used to obtain the initial clustering centers of the FCM clustering for the low-frequency subband image of the original image.The image segmentation experiments show that the proposed method is feasible.

    The methods in previous literatures were improved based on neoclassical economic theory,and the ratio of the actual total output to the total output under the optimal conditions of capital allocation was used to measure the situation of capital allocation between the industrial sectors of China.Using this method we estimated the capital allocation efficiency in China’s industrial sector.The capital allocation efficiency of China’s manufacturing industry shows a significant volatility,it is closely related to the change of the country’s industrialization process,its value remains at 47.6%~63.8%,and annual average is 55.8%.The current situation of capital allocation is unsatisfactory,and so it needs to be further optimized.
