中值滤波算法改进之C语言实现

代码如下,通过两种方法计算中值:

＃i nclude <stdlib.h>

int middle(int array[],int n)
{
   int i,j;
   int large=0,little=0;
   for(i=0;i<n;i++)
   {
      if(i>0&&((array[i]>array[i-1]&&large<little)||(array[i]<array[i-1]&&little<large)||array[i]==array[i-1]))
             continue;
      large=little=0;
      for(j=0;j<n;j++)
         if(j!=i)
        {
           if(array[j]>=array[i])
              large++;
           if(array[j]<=array[i])
              little++;
         }
   if(abs(large-little)<=3)
         break;
