我正在尝试实现具有N级量化的非均匀量化器。 我已经完成了一些工作并且它有效，问题是当N（级别数）超过“4”时它会进入无限循环。
如果有人能指出任何提示，知道错误的位置，我会很感激。

Vector <Integer> rightData = new Vector <Integer>();
averages.add(lowerAverage);
averages.add(upperAverage);
//FIND ALL AVERAGES
while (averages.size()<n)
{
//I THINK THE PROBLEM HAPPENS HERE AS IT KEEP PRINTING "loop"
System.out.println("loop");
for (int i = 0; i < image.size(); i++)
{
if (Math.abs(image.get(i)-lowerAverage) <= Math.abs(image.get(i)-upperAverage))
