[图形图像处理] BilateralFilter

c实现双边滤波。 双边滤波是一种非线性滤波器,它可以达到保持边缘、降噪平滑的效果。和其他滤波原理一样,双边滤波也是采用加权平均的方法,用周边像素亮度值的加权平均代表某个像素的强度,所用的加权平均基于高斯分布[1]。最重要的是,双边滤波的权重不仅考虑了像素的欧氏距离(如普通的高斯低通滤波,只考虑了位置对中心像素的影响),还考虑了像素范围域中的辐射差异(例如卷积核中像素与中心像素之间相似程度、颜色强度,深度距离等),在计算中心像素的时候同时考虑这两个权重。

[图形图像处理] k means

k均值聚类算法(k-means clustering algorithm)是一种迭代求解的聚类分析算法,其步骤是,预将数据分为K组,则随机选取K个对象作为初始的聚类中心,然后计算每个对象与各个种子聚类中心之间的距离,把每个对象分配给距离它最近的聚类中心。聚类中心以及分配给它们的对象就代表一个聚类。

[图形图像处理] kmeans

算法首先随机从数据集中选取 K个点作为初始聚类中心,然后计算各个样本到聚类中的距离,把样本归到离它最近的那个聚类中心所在的类。计算新形成的每一个聚类的数据对象的平均值来得到新的聚类中心,如果相邻两次的聚类中心没有任何变化,说明样本调整结束,聚类准则函数已经收敛。本算法的一个特点是在每次迭代中都要考察每个样本的分类是否正确。若不正确,就要调整,在全部样本调整完后,再修改聚类中心,进入下一次迭代。如果在一次迭代算法中,所有的样本被正确分类,则不会有调整,聚类中心也不会有任何变化,这标志着已经收敛,因此算法结束。
The algorithm first randomly selects K points from the data set as the initial cluster center, then calculates the distance from each sample to the cluster, and returns the sample to the class in which the nearest cluster center is located. The new clustering center is obtained by calculating the average value of the newly formed data objects. If there is no change in the two adjacent cluster centers, the clustering criterion function has been converged. One of the characteristics of this algorithm is to examine the correctness of each sample in each iteration. If it is not correct, we need to adjust it. After all the samples are adjusted, modify the cluster center and enter the next iteration. If all the samples are correctly classified in an iterative algorithm, there will be no adjustment and there will be no change in the cluster center, which signifies the convergence and the end of the algorithm.
