摘要
提出了一种适用于红外成像GIF引信图像序列处理的改进Otsu图像序列分割算法,该算法充分利用了弹道终端导引头红外图像序列的特点,通过压缩参与Otsu阈值运算的灰度范围和合理增大图像平面上的采样间隔,从而大大降低了图像分割算法的运算量,而分割质量基本保持不变,与原Otsu算法相比,改进的Otsu算法具有更好的实时性和有效性。
An improved Otsu image sequence segmentation algorithm that used for image sequence processing of GIF fuze was presented. The image sequence segmentation algorithm was designed based on the features of IR image sequence of seeker during terminal guidance,through decrease the range of gray scale and increase the sampling step in threshold design, the compute capacity was decreased and the quality of segmentation were alike. The experimental results show that the improved Otsu algorithm was more feasible than traditional Otsu algorithm.
