| 摘 要： | 兴趣点是图像中重要的几何特征，兴趣点的准确检测对于图像处理具有重要意义。为了优化SUSAN算法，提高算法的有效性，对SUSAN兴趣点检测算法中阈值的确定提出了改进。在图像每个像素的SUSAN模板中首先计算阈值t的初值，在利用迭代法获得终值，使其在各种不同的对比度下仍能正确检测兴趣点。实验结果证明了该方法的有效性。

| Abstract: | Interesting point is an important geometrical feature of image.The exact interesting point detection is vital to image processing.To improve efficiency and optimize SUSAN arithmetic,an improved way of determining the threshold of SUSAN operator is proposed.The initial value of threshold was calculated in every single SUSAN template.The final value of threshold was obtained using iterative segment.This way made it possible to pick up the right interesting point in all kinds of gray contrast.The experimental ... |
