绣花问题是连续型的填充,在不同区域的缝制过程中,缝针不能提针,因此不能用一般的离散型区
域填充方法处理。本文运用几何计算和图论理论提出了一个绣花缝针轨迹自动生成算法:先对轮廓走向进行
定义,通过轮廓铅垂方向的局部极值点的分割线将图案从上向下进行分割,采用交点的特征值比较彻底的解
决了分割时的重点问题,将图案区域准确的划分成缝针能一次完成的若干个节点。在此基础上根据节点的邻
接关系建立节点的邻接“图”,通过图论中半哈密尔顿路径或深度遍历方法找到节点的遍历(缝制)序列和每
个节点的缝制方向,最后可对设定的起点、终点和缝针间隔的条件自动提供缝针的走向轨迹。(In the process of embroidering, needle can not hang up for changing to a different area. Therefore, Embroider
problem could be abstract as a continuous area-filling work. Considering disperse area-filling methods can not process this
problem well. Based on geometry computing and graph theory, an algorithm of finding path of embroidering needle are
proposed in this paper. First, outline orientations are defined, and finding all local extreme points of inner outline on their
gravitational orientation to build sectioning lines so as to divide the picture. By using intersection point character the
overlap point problem was solved perfectly. Therefore, the picture is divided into some nodes which can be finished alone.
Then, based on connections of these nodes, an adjacency graph of nodes was built. Using half-Hamilton path or depth-first
search method, both embroidering sequence and direction of these nodes could be got from the graph. Finally, from a
defined start-point, end-point)

混合高斯(Mixture of Gaussian, MOG) 背景建模算法和Codebook 背景建模算法被广泛应用于监控视频的运动目标检测问题, 但混合高斯的球体模型通常假设RGB 三个分量是独立的, Codebook 的圆柱体模型假设背景像素值在圆柱体内均匀分布且背景亮度值变化方向指向坐标原点, 这些假设使得模型对背景的描述能力下降. 本文提出了一种椭球体背景模型, 该模型克服了混合高斯球体模型和Codebook 圆柱体模型假设的局限性, 同时利用主成分分析(Principal components analysis, PCA) 方法来刻画椭球体背景模型, 提出了一种基于主成分分析的Codebook 背景建模算法. 实验表明, 本文算法不仅能够更准确地描述背景像素值在RGB 空间中的分布特征, 而且具有良好的鲁棒性.(The background modeling algorithm of mixture of Gaussian (MOG) and codebook is widely used in moving
object detection of surveillance video. However, the ball model of MOG usually assumes that the three components of
RGB are independent, while the cylinder model of codebook assumes that the value of background pixel is distributed
uniformly within the cylinder and the changing direction of brightness points to the origin of the coordinate system.
These assumptions reduce the descriptive capability for background modeling. Therefore, the paper proposes an ellipsoid-
based background model, which overcomes the MOG and codebook0s limitations. By using principal component analysis
to depict the ellipsoid background model, a novel PCA-based codebook background modeling algorithm is proposed.
Experiments show that this algorithm can not only give more accurate description of the distribution of background pixels
but also have a better robustness.)
