中文摘要：

提出了一种基于线扩散函数的运动目标高精度轮廓特征提取算法（LDFM）。对该算法提取轮廓边缘的精度和抑噪去伪方法进行了分析，并将其应用于飞机序列影像的轮廓提取中，取得了预期的实验结果。

英文摘要：

A highLaccurate outline detection algorithm based on line diffusion function model（LDFM algorithm） has been proposed in this paper. Then analysis of extraction accuracy and blunder eliminate and noise constrain have been done. Finally this algorithm has been used to extract aircraft outline from image sequences and satisfactory results has been obtained.
