图像最近邻算法 使用5近邻 取最小的前五个作为待测例-NearestNeighbor

KNN分类，图像处理，(kNN，k-NearestNeighbor），数据挖掘(k-NearestNeighbor is a kind of algorithm of Data mining)

采用最近邻法对图像进行插值，进行n倍的缩放，有示例图片，有注释，可运行，欢迎交流。(Using the nearest neighbor method for image interpolation, n times zoom, there are examples of pictures, notes, can run, welcome exchanges.)
