Images passed to your application are not always of the same size as your
templates. To compare them you might need to up scale or down scale them to
the template size. It is preferred that when comparing you check the size of the
template to b

该代码实现了以2为因子的图像升采样和降采样功能。
降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。
升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。
降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和
