Description: 在图像模板匹配问题中,基于像素灰度值的相关算法尽管已经十分普遍,并得到广泛的应用,但目前此类算法都还存在有时间复杂度高、对图像亮度与尺寸变化敏感等缺点.为了克服这些缺点,提出一种新的基于图像灰度值的编码表示方法.这种方法将图像分割为一定大小的方块(称为R-块),计算每个R-块图像的总灰度值,并根据它与相邻R-块灰度值的排序关系进行编码.然后通过各个R-块编码值的比较,实现图像与模板的匹配.新算法中各个R-块编码的计算十分简单 匹配过程只要对编码值进行相等比较,而且可以采用快速的比较算法.新算法对像素灰度的变化与噪声具有鲁棒性,其时间复杂度是O(M2log(N)).实验结果表明,新算法比现有的灰度相关算法的计算时间快了两个数量级.-err

Description: BM 算法是一个较优的模式匹配算法。一般,如果不考虑模式串的长度,一个具有时间复杂度O(n)的算法应该是最优的了,但是事实不是如此。BM算法可以实现更高效率的模式匹配。分析和实验说明,BM匹配算法对于那些字符集比较大,而模式串中出现的字符比较少的时候,工作效率最快。而且,考虑KMP匹配方式的优化,可以结合KMP匹配和BM匹配,进一步提高效率。
-BM algorithm is a better pattern matching algorithm. General, if we do not consider the length of pattern, a time complexity O (n) algorithm should be optimal, but the fact is not the case. BM algorithm can realize more efficient pattern matching. Analysis and experiments, BM-matching algorithm for those relatively large character set, and the mode string of characters appearing in less time, the efficiency of the fastest. Moreover, consider the KMP matching optimization, you can match the combination of KMP and BM match, and further improve efficiency.

Description: 基于边缘特征的图像配准算法源码
基于边缘特征的图像配准算法是将不同时间、不同的传感器(成像设备)或不同条件下(天候、照度、摄像位置和角度等)获取的同一场景的两幅或多幅图像根据其边缘特征进行匹配、叠加的处理,最终生成一幅全景图像的方法。该方法具有抗噪性强,匹配速度快,误匹配率低,适用于多种类型的图像等优点,主要可以运用于以下领域:
(1)军事研究领域,如飞行器辅助导航系绞、武器投射系统的末制导以及寻地等应用研究;
(2)医学图像分析,如数字剪影血管造影DSA血管造影术、肿瘤检测、白内障检测、CT、MRI、 PET、 SPECT图像结构信息融合;
(3)模式识别,如特征识别、波形分析、签名证实、目标物运动跟踪、序列图像分析等;
(4)计算机视觉,可用于目标定位、自动质量控制等;
(5)遥感数据分析,多电磁波段图像信息融合,如多谱段的等场景分类、定位和识别定义好的或已知特征的场景、自然资源监控、核生长监控、市区增长检测等。
本算法实现使用VC++6.0为开发环境,目前只支持灰度图像,感兴趣的朋友可以进一步扩展。-Image registration is a fundamental problem in image processing, which is a process to match two or more images of the same scene taken at different times, from different viewpoints, or by different sensors. Image registration is an important technique for a great variety of applications such as medical image analysis, computer vision, remote image data analysis, image information fusion, and the recovery of the 3–D characteristics of a scene.

Description: 在快匹配运动估计算法中,它的计算复杂度可以描述成:运算量=搜索点×块匹配准则.该表达式可以这样解释,在快匹配准则确定的情况下,如果一个匹配点的单位运算量确定了,这时动动估计的动算量就有直接取于搜索的点数,也就是取决于运动估计的搜索算法,实现了三步搜索法-Match the fast motion estimation algorithm, its computational complexity can be described as: Operational × volume = search block-matching criteria points. The expression can be interpreted in such a way, the fast matching criterion to determine the circumstances, if a match point of the unit operator determine the amount, and then moving moving moving estimate of the volume operator has direct access to the points in the search, that is, depends on the motion estimation search algorithm, to achieve a three-step search method
