摘要
介绍了一种数字图像边缘识别的滑动拟合法,采用多项式函数对跨边缘的像素序列进行分段滑动拟合。将分段拟合法与不分段拟合进行比较,结果显示,即使采用低阶多项式分段拟合,效果仍然优于高阶多项式不分段拟合。滑动拟合法为边缘识别的研究提供了一种新的思路。
A moving fitting method for edge detection is proposed in this paper. Polynomial function is used for the curve fitting of the column of pixels near the edge. Compared with polynomial fitting method without sub-segment, even with low order polynomial, this method＇s effects of moving fitting are significantly better than that with high order polynomial fitting without subsegment.
