Description: 对于阵地的生存概率计算, 可以使用文献1 中的解析公式作粗略估算, 具体方法为, 把整个阵地看作一
个点目标, 即以阵地的中心作为攻击点。求解出某型弹对阵地的破坏半径, 代入解析式即可。但在实际情况
下, 相对于来袭武器的破坏半径, 把阵地看作点目标必然引起很大的误差。所以, 本文拟用层次分析法对阵地
这个系统进行可能受到攻击的目标分类, 按各分项指标的重要性得出系统的生存概率-Probability of survival for the position calculation, you can use the literature in a rough estimate for analytical formula, the specific method, the whole position as a point target, that is, to position the center point of the attack. Solving for the position of a certain type of bomb damage radius, can be incorporated into the analytical. However, in practice, as opposed to the destruction of the radius of incoming weapons, and position as a point target is bound to lead to significant error. Therefore, this article intended to be position-level analysis of this system may be targeted by the classification of the sub-indicators in accordance with the importance of the survival probability derived system

Description: 针对Harris角点检测算法对T型和斜T型角点存在定位不准确以及运算速度慢的问题,提出了一种改进算法.改进算法计算目标像素点的8邻域范围内与之灰度相似的点的数目,然后对目标像素点周围其他像素点按同样方法处理,并对得到的计算数据进行比较,分析出局部范围内的像素点的灰度值分布.根据比较结果,从中遴选出部分像素点作为下一步角点检测的计算对象,并计算其角点响应函数值,如果角点响应函数值大于设定的阈值,该点则会被确定为最终的角点.实验结果表明:改进算法的角点检测时间仅为原算法的14.3 ,并实现了对T、斜T型角点准确定位,提高了Harris角点检测算法的检测效率和精度.-Harris corner inspection

Description: 对于细胞图像序列中多目标的追踪是细胞运动研究中的难点，针对高密度细胞图像中细胞运动的复杂性，本文提出一个细胞分割和追踪的系统。在细胞分割部分，针对实验所用细胞图像序列的特点，本文分别采用了不同的分割方法。在基本的细胞分割后，由于得到的分割图像存在着一些粘连细胞，为了将之分离，采用了基于Freeman code法对细胞轮廓进行跟踪编码。根据编码所得的链码特征分析细胞的轮廓形态，找出粘连细胞图像中的凹角点，再将凹角点进行分组配对完成粘连细胞的分离。在追踪部分，针对细胞的运动特性，将细胞分为惰性细胞和非惰性细胞，分别采用区域重叠法和拓扑约束法进行追踪。针对高密度细胞追踪中由于细胞密集加上细胞分裂很容易导致错误追踪的问题，本文提出将面积项引入实现追踪的拓扑约束条件中，对原方法进行改进，有效的解决了这一问题，有助于提高追踪效率，特别是对于细胞密度比较大，且分裂频繁的细胞图像效果明显。另外，本文提出根据细胞数量设置产生图的距离门限，使算法的适用性更强 。-For cells in image sequences multi-objective tracking is cells, the difficulty in the studies of cellular density cell image motion complexity, this paper puts forward a cell division and tracking system.
