数字影像中目标角点定位的无阈值算法

Corner Finder of Digital Image Without Threshold

在分析现有角点定位算子的基础上,针对现有大部分角点定位算子在角点定位过程中需要选择适当的阈值,而阈值的选择本身比较困难的这一关键问题,提出了一种基于移动小窗口内最大值的无阈值的角点定位算法的基本思想。并通过实验来证明算法的有效性。实验结果表明,这种算法在理想的情况下具有非常好的角点定位效果,而对于复杂的非均质图像来说也有较好的定位效果。

This paper analyzes some corner finder arithmetic operators, aims at most of the corner finders need a threshold in the proceeding of corner location, but it is difficult to set a proper threshold. So, for overcoming these shortcomings of some corner finder operators, this paper proposes a method based on the maximum pixel in the small window of image. The result of experiment shows the operator proposed in this paper is very effective in ideal condition. In addition, this operator is also effective for complicated image.
