Description: 1．细胞边缘检测
（1） 原理：
Soble算子边缘检测---Soble微分算子是一种奇数大小（3×3）的模板下的全方向微分算子。Soble滤波器进行处理的结果，在视觉上只能感觉到该微分算子所提取
出的细节轮廓相对明显一些。
Laplacian算子边缘检测---用Laplacian二阶微分算子所提取出的细节多，说明二阶算子早对图像细节有很强的敏感性。
-1. Cell Edge Detection (1) Principle: Soble edge detection operator--- Soble differential operator is an odd size (3 × 3) of the template under the omni-directional differential operator. Soble filter processing result, the visual impression that the only differential operator out the details mentioned in the outline of a number of relatively obvious. Laplacian operator Laplacian edge detection--- with second-order differential operator referred out more details on second-order operator as early as the image details have a strong sensitivity.

Description: Contourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L距离计算图像间的相似度。对800幅纹理图像进行检索,本文方法比传统小波方法的平均检索查准率高出约2％到10％不等。实验结果表明,该方法改进了导向纹理的描述-Transform Contourlet inseparable combination of the direction of filtering group, have not expressed by wavelet multi-directional properties, can effectively capture the edge of natural image contour information. This paper analyzes the image ontourlet coefficient statistical characteristics, and take advantage of the generalized Gaussian function of the sub-band coefficient modeling layer. Based on this model was applied to the self-VisTex texture image database, using moment matching estimation method, extract the model parameters set, K2L use of distance-based similarity between images. Of 800 texture image retrieval, wavelet method than the traditional method of the average retrieval precision by about 2 to 10 range. Experimental results show that the method improves the texture-oriented description of

Description: 双向亚像素运动估计算法，具体步骤如下：
(1) 进行整像素精度的双向运动估计；
(2) 以(1)得到的运动矢量所指向的像素点为中心，内插1/2像素点，再进行双向运动估计；
依此类推，直到得到所需的像素精度为止。
