An edge detection method based on a good point set genetic algorithm

In order to improve the convergence rate of genetic algorithms based on edge detection, a novel edge detection method based on a good point set genetic algorithm (GGA) was proposed. The proposed method designed the crossover operation with the theory of good point set in which the progeny inherits the common genes of the parents which represent its family so as to improve the convergence rate of the genetic algorithm. Furthermore, before the algorithm was used for edge detection, the feature space of the image grey level was transformed into the feature space of the fuzzy entropy. Dissimilarity enhancement processing next was applied to the image by using a fuzzy entropy theory to filter the non edge pixels so as to reduce the scale of the solution domain. This approach offered another efficient way to improve the convergence rate. Experimental results show the proposed algorithm performs very well in terms of convergence rate. The detected edge image is well localized, thin, and robustly resistant to noise.     

Segmentation algorithm for urinary sediment image combiningwavelet transform and 2D Maximum entropy threshold

In order to solve the problem that urine sediment visible components cannot be segmented effectively because of complex components, complicated defocusing in image and poor discrimination between object and background, a method based on combination algorithm wis designed to segment urine sediment. The wavelet transform wis used to erase the effect of defocusing. Then morphology wis utilized to get the subimages that include the particles. The segmentation method combining the wavelet transform based segmentation and the two dimensional entropy threshold based segmentation wis employed to segment urine sediment visible components. Experimental results show that the proposed method can segment urinary sediment images effectively and precisely.

用最大熵法进行沥青路面工程实例的结构可靠性分析

结合工程实例以蒙特卡罗分析法为基本出发点,首先通过计算机根据弯沉和弯拉应力的功能函数来生成1000个功能函数的一个随机抽样,然后用大熵法拟合沥青路面的弯沉功能函数的密度函数,求出两种失效模式的失效概率。同时,把整个路段看作是一个由弯沉失效和弯拉应力失效的两种失效模式串联组成的网络系统,对整个系统进行了可靠性评估。     

An Evaluating Method of Human Resource Value Based on Rough Set

As the development of knowledge economic , human resource has been the core of the world economic .So searching the reasonable evaluating and managing methods becomes one of the hot issues which have been concerned by people . Traditional evaluating methods of human resource are simple and direct , but they greatly depend on people's subjective judgement and experience . In order to overcome the default , this paper puts forward the method of synthetically evaluation on rough sets, which takes advantage of the rough sets theory, the concept of information entropy and relative analysis to filter the original indexes, then to standardize the importance degree of every index and get the weight of every index. Synthetically valuation model and corresponding arithmetic are summed up. Finally the sample illuminates the validity and feasibility of this method.

利用最大熵原理、模糊集合论和河流水质恢复能力评价标准,为河流水质恢复能力综合评价提出了一种新的方法—基于最大熵的模糊评价法（FAME）。FAME综合考虑河流水质恢复能力评价的随机性和模糊性,定义加权广义距离表征待评价水体样本与标准样本的差异;把多维评价样本指标综合为一维指标值。根据隶属度值的大小对水体样本集进行统一评价,从而解决了各单项评价指标评价结果不一致问题,提高了河流水质恢复能力综合评价问题各层次的分辨力。通过实例研究,并对比遗传投影寻踪方法,验证了本方法的合理性和有效性。

不同确权法在农村居民点复垦潜力评价中的应用——以重庆市永川区为例

有效与合理地进行农村居民点复垦潜力评价分级,是顺利开展农村居民点复垦的重要环节。为此,在构建农村居民点复垦潜力评价分级指标体系的基础上,采用信息熵法和AHP法对永川区农村居民点复垦潜力进行评价分级,并进行对比分析,寻找对农村居民点复垦潜力分值影响的差异。研究结果表明,两种方法对农村居民点复垦潜力分值影响的顺序差相差较小,并且在农村居民点复垦潜力评价分级结果的空间分布上也基本吻合。研究认为,在农村居民点复垦潜力评价分级中,应该综合考虑两种方法的优点和劣势,以便提高评价分级的准确性和合理性。     

灰色关联-熵模型在珠三角水资源承载力评估中的应用

水资源承载力是影响区域可持续发展的关键因素之一,科学的评估水资源承载力可为合理促进水资源开发利用提供参考依据。以信息熵和灰色关联理论为基础,建立了基于灰色关联-熵的水资源承载力评估模型,对珠三角区域水资源承载力空间差异性进行分析,评估结果表明,2017年珠江三角洲地区影响水资源承载力的主要指标为单位面积污水排放量、人均水资源量、万元工业增加值用水量等,在评估体系的5个子系统中,水资源数量、水资源质量和用水水平的指标总权重为74%,珠三角城市水资源承载力由低到高分别为:深圳<佛山<广州<东莞<中山<珠海<江门<惠州<肇庆。结合各地市水资源利用现状,提出了合理开发利用水资源的建议,同时为珠三角水资源承载力评估工作提供了更加合理的方法。
