说明: 本文以k-means算法为背景,引入信息熵相关知识,从而实现全自动分割图像。然而在利用混合高斯模型对图像进行数据分析时,会发生一定的过拟合现象,导致我们得不到预期的聚类数目。本文设计合理的合并准则,令模型简化,有效地消除过拟合现象,使得最后得到的聚类数目与预期符合。,设计合理的准则改进了图像的全自动分割方法,使得分割结果更加优化(In this paper, k-means algorithm is used as the background, and information entropy related knowledge is introduced to realize full-automatic image segmentation. However, when the Gaussian mixture model is used to analyze the image data, there will be some over-fitting phenomenon, resulting in that we cannot get the expected number of clusters. In this paper, a reasonable merging criterion is designed to simplify the model and effectively eliminate the over-fitting phenomenon, so that the final clustering number is in line with the expectation. A reasonable criterion is designed to improve the automatic image segmentation method and make the segmentation result more optimized.)

Inpainting--on-Wavelet-
图像修复是图像处理的一个重要问题。这是一个困难的问题,同时填写在地区缺少图像信息的纹理和结构。以损坏的图像inpaint失踪的结构和纹理信息,基于小波分解的图像修补算法提出。首先损坏的图像分解成子图像和纹理结构,利用小波子图像转变。然后,地区结构中缺少的信息的子图像重建曲率驱动扩散(CDD),算法,而在同一区域的纹理子图像填写基于改进的纹理合成的典范 最后,恢复的图像,通过重组,结构和纹理恢复的结果。大量的实验表明,该算法可以快速,高效地恢复在同一时间的结构和纹理信息,视觉效果和峰值信噪比比(PSNR)比同类算法更好。(Image inpainting is an important problem image processing. It is a difficult problem to simultaneously fill-in the
texture and structure in regions of missing image information. In order to inpaint the damaged image with both
missing the structure and texture information, an image inpainting algorithm based on wavelet decomposition is
presented. First the damaged image is decomposed into structure sub-image and texture sub-image using the wavelet
transformation. Then, the sub-image with the region of missing information in the structure is reconstructed by
Curvature-Driven Diffusions (CDD) algorithm, while the same region in the texture sub-image is filled-in with the
improved texture synthesis based on exemplar Finally, the restored image is given by recombining the structure and
texture restored results. A large number of experiments show that the proposed algorithm can quickly and efficiently
restore the structure and texture information at the same time, and the visual eff)

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

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)
