基于局部熵的目标检测与跟踪算法研究已有一些文章介绍，主要针对其应用、改进等方面。通过对点目标局部熵特点的深入研究，定量分析其在不同点目标对比度情况下的局部熵值变化，以及不同尺度子域对点目标作用，研究其中的相互关系，得出点目标的局部熵值定量分析算法。经不同灰度点目标与背景相同灰度差的情况下和具有相同对比度情况下点目标局部熵值的计算，验证了算法及分析的正确性。为点目标检测(如红外目标等)提供定量分析的基础。

The local entropy algorithms (LEA)for aerial target have been introduced in the past.which were focused on its applications and improvements.By the research and analysis about the features of the dot target based on the local entropy in detail and deeply,the relation-ships are studied quantitatively for the variations of the local entropy values for the dot target with the different contrast and the effects to the dot target from the different size of the neigh-bours.In this paper,it is calculated for the local entropy values at the different grey dot tar-gets with the same differences to their backgrounds and by the dot targets with the same con-trasts,which validates the algorithm and analysis.In the future,it provides the quantitative a-nalysis base for the aerial dot target,such as infrared targets.
