However, the centroid tracking algorithm based on the image gray-mean segmentation fails when tracking small target images.

但是这种基于图像灰度均值分割的形心跟踪算法对于小目标图像都会跟踪失败。

As the main difficulty in small target image segmentation is analyzed by using routine method, a new method basing on two-time segmentation of the processed images is applied.

研究分析了常规分割算法在低对比度弱小目标图像分割中存在的主要困难，提出了对预处理和图像采取两级分割的方法。
