Image segmentation is a process of separating the target contour after marking the objects of the background according to the prior knowledge.
图像分割就是根据目标和背景的先验知识对图像中的目标背景进行标记，然后将要识别的目标从背景中分离出来的一个过程。
The method can converge to target contour rapidly. Experiments show that it can track moving target fast and exactly, and it is robust to noise.
实验证明该方法运算速度快、能够快速地收敛到目标轮廓、准确地跟踪目标，并具有一定的抗噪能力。
These are compared with simulating plates of target contour, wind tunnel test data, high altitude test data. Good flow field quality is given for the typical engine.
将这些技术参数和图谱与模拟板的目标图谱数据、风洞吹风试验数据及高空台试验推算结果进行了综合分析与对比，较完整地表述了发动机进口的流场品质。
