• improved hough transform - 引用次数：15

  An improved Hough transform is proposed in this paper to detect the index in automatic identific- ation of index-instrument. We use two-threshold value to reduce memory required, time in calculation of hough transform, and the chance of false lines matching.

  本文针对指针式仪表自动读取中的指针提取提出了一种改进的Hough变换算法,利用双阈值大大提高了Hough变换直线提取的运算速度,降低了占用内存,同时减少了直线误匹配的机会。
