The two regulations supporting each other, the < code > adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard; < rule > around the party discipline, disciplinary ruler requirements, listed as "negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the" bottom line ". Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process; the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; the fourth part on how to grasp the implementation of the two regulations of the party. < code > and < Regulations > revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines > and < Chinese Communist Party discipline and Punishment Regulations > column 1 by 2015 to strengthenparty laws and regulations focus. Two party regulations revision work lasted a Y ears, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation; follow the correct direction, grasp the limited goals, adhere to the party's leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the < code > and < rule >, reflects the party's 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulationsrepeat and Criminal law and other laws and regulations repeat; the fourth is to "clean" the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level leading cadres above. < rule > is in 1997 < Chinese Communist Party disciplinary cases (Trial) > based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to < the criterion of a clean and honest administration > and < rule > the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness.

(1) false debate the central policies and undermine the Party of centralized and unified the problem is made in accordance with the provisions of the party constitution. Constitution in general programme requirements adhere to democratic centralism is one of the requirements of the construction of the party must adhere to the four cardinal. Applicationof this principle is not only the party the basic organization principle and is also the mass line in party life, it requires that we must fully develop inner-party democracy, respect for the dominant position of Party members, safeguarding the Party member democratic rights, give full play to the enthusiasm and creativity of the party organizations at all levels and Party members, at the same time, also must implement the right concentration, ensure the party's mission < the chaos in unity and concerted action to ensure that the party's decision to get quickly and effectively implementing.

For example, after the investigation does not take the initiative to explain the situation, but to engage in offensive and defensive alliance, hiding the stolen money is against survey organization, is a violation of the behavior of political discipline. Article 24 of the original > < Regulations, although the provisions of the interference, hinder group review the behavior of the fabric can be severely or 13 Aggravated punishment, but did not put this kind of behavior alone as a discipline for qualitative amount of discipline. > < new regulations increase the Article 57, "anti organization review, one of the following acts, given a warning or serious warning; if the circumstances are relatively serious, giving removed from or placed on probation within the party post; if the circumstances are serious, give。

我们假设为SAR图像分割分配参数，并与水平集模型相结合。

分布属于G分布中的一种，处于数据建模的目的，它们已经成功的被用于振幅SAR图像中不同区域的建模。

这种统计数据模型是驱动能量泛函执行区域映射的基础，被引用到水平集传播数值方案中，将SAR 图像分为均匀、异构和极其异构区域。

此外，我们引入了一个基于随机距离和模型的评估过程，用于量化我们方法的鲁棒性和准确性。

实验结果表明，我们的算法对合成和真实SAR 数据都具有准确性。

+简介1、Induction（简介）合成孔径雷达系统是一种成像装置，采用相干照明比如激光和超声波，并会受到斑点噪声的影响。

在SAR图像处理过程中，返回的是斑点噪声和雷达切面建模在一起的结果。

这个积性模型（文献[1]）因包含大量的真实SAR数据，并且在获取过程中斑点噪声被建模为固有的一部分而被广泛应用。

因此，SAR图像应用区域边界和目标检测变得更加困难，可能需要斑点去除。

因此，斑点去除是必需的，有效的方法可以在文献[2][3][4][5][6][7][8][9][10]中找到。

对于SAR图像分割，水平集方法构成一类基于哈密顿-雅克比公式的重要算法。

水平集方法允许有效的分割标准公式，从文献[12]中讨论的传播函数项可以得到。

经典方法有着昂贵的计算成本，但现在的水平集的实现配置了有趣的低成本的替换。

计算机图像处理——图像的概念及整体课程体会学院：xxx班级：xxx姓名：xxx学号：xxxx2011/5/16我们本门课程共讲八章，通过十多周的学习，我学到了关于计算机图像处理的基本知识，对计算机图像处理有了更深一层次的理解。

以下是图像的基本概念及我学习本课程的体会。

图像的基本概念1.1图像数字化图像按表现方式不同分为连续图像和离散图像：连续图像——日常生活中见到的图像一般是连续形式的模拟图像，可由一个二维连续函数f （x ，y ）来描述。

其中：(x, y)是图像平面上任意一个二维坐标点， f (x, y)则是该点颜色的深浅。

离散图像—— 用一个数字阵列表示的图像。

阵列中每一个元素称为像素，像素是组成数字图像的基本元素。

数字图像处理的一个先决条件就是将连续图像经采样、量（离散）化，转换为数字图像。

所谓的图像数字化是指将模拟图像经过离散化之后，得到用数字表示的图像。

图像的数字化包括了空间离散化（即采样）明暗表示数据的离散化（即量化）由于图像是一种二维分布的信息，对它进行采样操作也是二维的。

采样示意图采样时的注意点是：采样间隔的选取。

采样间隔太小，则增大数据量；太大，则会发生信息的混叠，导致细节无法辨认。

分辨率 是指映射到图像平面上的单个像素的景物元素的尺寸。

单位：像素/英寸，像素/厘米(如：扫描仪的指标 300dpi)。

分辨率 或者是指要精确测量和再现一定尺寸的图像所必需的像素个数。

单位：像素×像素(如：数码相机指标30万像素 (640×480))。

量化是将各个像素所含的明暗信息离散化后，用数字来表示称为图像的量化；一般的量化值用整数来表示。

充分考虑到人眼的识别能力之后，目前非特殊用途的图像均为8比特(bit)量化，即用0~255描述“黑~白”。

采样行隔采样间隔量化可分为均匀量化和非均匀量化。

均匀量化是简单地在灰度范围内等间隔量化。

非均匀量化是对像素出现频度少的部分量化间隔取大，而对频度大的量化间隔取小。
