Microaneurysm detection method based on Canny edge detection and appearance feature

糖尿病性视网膜病变进行早期筛查可以减少疾病的发展并且阻止随后的视力损害。微血管瘤是糖尿病性视网膜病变的早期临床症状，可以通过微血管瘤检测对糖尿病性视网膜病变进行早期筛查。针对眼底图像中视网膜血管、视盘、渗出物以及微血管瘤之间的相互关系，在红色通道和绿色通道加权图上定位出视盘，在绿色通道上采用基于简单统计的自适应双阈值Canny算子进行边缘检测，并进行封闭区域的填充。设定阈值消除大面积对象并移除视网膜血管、视盘和渗出物得到微血管瘤的候选区域，最后根据形状特征和颜色特征从候选区域中得到真正的视网膜微血管瘤。实验结果表明，该算法能够有效提取视网膜眼底图像中的微血管瘤，敏感性和阳性预测值分别达到92%和86%，优于现有一些典型的微血管瘤检测方法，能够精确地检测出微血管瘤，可用在糖尿病性视网膜病变早期筛查中。The early screening of the diabetic retinopathy can restrain the development of disease and prevent the subsequent vision impairment.The microaneurysm is the earliest clinical sign of the diabetic retinopathy,and its detection can perform the early screening for the diabetic retinopathy.Considering the interrelation among the retinal blood vessel,optic disc,exudates and microaneurysm in the eye ground image,the optic disc is located in the weighted images of the red channel and green channel.The adaptive dual?threshold Canny operator based on simple statistics is adopted in the green channel to perform the edge detection,and fill the enclosed region.The threshold is set to eliminate the large area objects,and remove the retinal blood vessel,optic disc and exudates to acquire the candidate area of the microaneurysm,in which the real retina microaneurysm is obtained according to the shape feature and color feature.The experimental results show that the method can extract the microaneurysm in the retina eye ground image,the sensitivity and positive predictive values can reach up to92%and86%re?spectively,the method is superior to some typical microaneurysm detection methods,can detect the microaneurysm accurately,and is useful for the early screening of the diabetic retinopathy.国家自然科学基金项目(60827002);福建省自然科学基金项目(2012J05116);福建省教育厅项目(JA13037

我国储蓄投资相关性的实证分析

本文利用我国1978——2004年期间的样本数据,对我国储蓄与投资的相关性进行了实证研究。VEC模型的结果显示我国居民储蓄、政府储蓄与投资之间存在长期正相关的均衡关系和显著的短期动态调整机制。同时,Granger因果检验说明了我国居民储蓄与投资之间可能存在双向Granger因果关系,而政府储蓄虽然对投资影响较大,但它与投资之间并不存在Granger因果关系。资本形成的真正来源最终还是要依赖于居民储蓄

引力模型在城镇体系规划中的应用——以厦门市同安区为例

引力模型在区域间经济社会关联度测定中有着广泛的应用。传统的引力模型多以宏观经济社会数据与微观社会现象数据相结合,从而得出区域间联动协作机理,随着城市大数据的普及,数据源的开放使引力模型有更多的优化方向。本文以区域产业大数据为基础,应用引力模型研究城镇体系结构特征,并结合经济社会发展现状与城乡空间发展潜力评估,对城镇体系规划进行科学性与合理性的优化,并以厦门市同安区为例,阐述应用引力模型进行城镇体系规划的过程。国家自然科学基金项目（41671141）福建省自然科学基金项目（2015J01226）厦门大学中央高校基本科研业务费资助项目（20720170046）厦门市科技局项目（3502Z20183005

"Financial Analysis by using SEM diagram in case of Sankyo Seiko Co., Ltd."

"ROE is widely used as financial analysis techniques. In case of downsizing companies such as Sankyo Seiko, the conventional financial analysis technique often gives misleading results, because lower sales results should give a negative impression to investors. On the other hand, factor analysis can assist a clear view on the correlation between factors, and finally arrow diagrams with degrees of fitness often visualize financial positions by using SEM.

Study on three proxy variables of China's GDP : From the perspective of multiple regression analysis

The aim of this study is to examine the usefulness of multiple regression analysis by conducting an analysis using Chinese GDP as an objective variable and the Li Keqiang index， namely， electricity usage by the industrial sector， railway freight quantity ， and growth of bank loans as explanatory variables. Firstly， we used correlation analysis to determine the correlation between our objective variable and explanatory variables. We found the explanatory variables electricity usage by the industrial sector and growth of bank loans to have a strong correlation with objective variable GDP. However， this correlation analysis found only weak correlation between railway freight quantity and GDP. From this study， we learned that if we add road freight quantity to railway freight quantity，using the resulting freight quantity as an explanatory variable，there was a strong correlation with GDP. We also found that when a revised version of the Li Keqiang index is used， there is a very strong correlation between these three explanatory variables and GDP. Additionally， we considered multicollinearity while conducting this study. The fact that these three new variables-specific economic activities-each showed strong correlation with China's GDP suggests that GDP statistics accurately reflect economic conditions. Therefore， Chinese GDP statistics are useful. We also believe that these three new variables are proxy variables for GDP
